  {"abstract":"The aim of mitosis is to produce two daughter nuclei, each containing a chromosome complement identical to that of the mother nucleus. This can be accomplished through a variety of strategies, with \"open\" and \"closed\" modes of mitosis positioned at the opposite ends of the spectrum and a range of intermediate patterns in between. In the \"closed\" mitosis, the nuclear envelope remains intact throughout the nuclear division. In the \"open\" division type, the envelope of the original nucleus breaks down early in mitosis and reassembles around the segregated daughter genomes. In any case, the nuclear membrane has to remodel to accommodate the mitotic spindle assembly, chromosome segregation and formation of the daughter nuclei. We have recently shown that within the fission yeast clade, the mitotic control of the nuclear surface area may determine the choice between the nuclear envelope breakdown and a fully \"closed\" division. Here we discuss our data and argue that comparative cell biology studies using two fission yeast species, Schizosaccharomyces pombe and Schizosaccharomyces japonicus, could provide unprecedented insights into physiology and evolution of mitosis.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Gu Y, Yam C, Oliferenko S","authors_abbrev":"Gu Y et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Review or comment","citation":"Nucleus 2012 May;3(3):220-5","cv_annotations":{},"doi":"10.4161/nucl.19514","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2012","pubmed_entrez_date":"2012-05-11","pubmed_publication_date":"May 2012","terms_by_termid":{},"title":"Divergence of mitotic strategies in fission yeasts.","uniquename":"PMID:22572960"}

  {"abstract":"Membrane function is fundamental to life. Each species explores membrane lipid diversity within a genetically predefined range of possibilities. How membrane lipid composition in turn defines the functional space available for evolution of membrane-centered processes remains largely unknown. We address this fundamental question using related fission yeasts Schizosaccharomyces pombe and Schizosaccharomyces japonicus. We show that, unlike S. pombe that generates membranes where both glycerophospholipid acyl tails are predominantly 16-18 carbons long, S. japonicus synthesizes unusual \"asymmetrical\" glycerophospholipids where the tails differ in length by 6-8 carbons. This results in stiffer bilayers with distinct lipid packing properties. Retroengineered S. pombe synthesizing the S.-japonicus-type phospholipids exhibits unfolded protein response and downregulates secretion. Importantly, our protein sequence comparisons and domain swap experiments support the hypothesis that transmembrane helices co-evolve with membranes, suggesting that, on the evolutionary scale, changes in membrane lipid composition may necessitate extensive adaptation of the membrane-associated proteome.","alleles_by_uniquename":{"SJAG_01458:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01458","name":"acb1delta","uniquename":"SJAG_01458:allele-1"}},"annotation_curators":[{"annotation_count":4,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana Oliferenko","orcid":"0000-0002-8138-6851"}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2021-07-09","authors":"Makarova M, Peter M, Balogh G, Glatz A, MacRae JI, Lopez Mora N, Booth P, Makeyev E, Vigh L, Oliferenko S","authors_abbrev":"Makarova M et al.","canto_added_date":"2021-05-10 02:37:19","canto_annotation_status":"APPROVED","canto_approved_date":"2021-07-09 13:38:09","canto_curator_name":"Snezhana Oliferenko","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2021-07-09 13:38:09","canto_session_key":"801e82954edbb6c1","canto_session_submitted_date":"2021-07-09 13:38:00","canto_triage_status":"Curatable","citation":"Curr Biol 2020 02 03;30(3):367-380.e8","cv_annotations":{"cellular_component":[{"annotations":[114135],"is_not":false,"summary":null,"term":"GO:0005801"},{"annotations":[114137],"is_not":false,"summary":null,"term":"GO:0005829"}],"single_locus_phenotype":[{"annotations":[114136],"is_not":false,"summary":null,"term":"FYPO:0000719"}]},"doi":"10.1016/j.cub.2019.11.043","gene_count":4,"genes_by_uniquename":{"SJAG_00816":null,"SJAG_01458":null,"SJAG_04107":null,"SJAG_04972":null},"genotypes_by_uniquename":{"acb1delta":{"display_name":"acb1delta","display_uniquename":"acb1delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01458:allele-1","expression":"Null"}]}]}},"ltp_gene_count":4,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[{"evidence":"Co-purification","gene_uniquename":"SJAG_04972","interactor_uniquename":"SJAG_04107","reference_uniquename":"PMID:31956022","throughput":"low"}],"publication_year":"2020","pubmed_entrez_date":"2020-01-21","pubmed_publication_date":"03 02 2020","terms_by_termid":{"FYECO:0000126":null,"FYPO:0000719":null,"GO:0005801":null,"GO:0005829":null},"title":"Delineating the Rules for Structural Adaptation of Membrane-Associated Proteins to Evolutionary Changes in Membrane Lipidome.","uniquename":"PMID:31956022"}

  {"abstract":"The present work demonstrates that yeasts belonging to the Schizosaccharomyces genus release a high quantity of polysaccharides of cell wall origin starting from the onset of the alcoholic fermentation. By the end of the alcoholic fermentation, all of the Schizosaccharomyces yeast strains released a quantity of polysaccharides approximately 3-7 times higher than that released by a commercial Saccharomyces cerevisiae yeast strain under the same fermentative conditions of synthetic juice. A higher content of polysaccharide was found in media fermented by Schizosaccharomyces japonicus with respect to that of Schizosaccharomyces pombe. Some of the strains evaluated were also able to produce high levels of pyruvic acid, which has been shown to be an important compound for color stability of wine. The presence of strains with different malic acid consumption patterns along with high polysaccharide release would enable production of naturally modified wines with enhanced mouth feel and reduced acidity. The chemical analysis of the released polysaccharides demonstrated divergence between the two yeast species S. pombe and S. japonicus. A different mannose/galactose ratio and a different percentage of proteins was observed on the polysaccharides released by S. pombe as compared to S. japonicus. Analysis of the proteins released in the media revealed the presence of a glycoprotein with a molecular size around 32-33 kDa only for the species S. japonicus. Mass spectrometry analysis of carbohydrate moieties showed similar proportions among the N-glycan chains released in the media by both yeast species but differences between the two species were also observed. These observations suggest a possible role of rapid MALDI-TOF screening of N-glycans compositional fingerprint as a taxonomic tool for this genus. Polysaccharides release in the media, in particular galactomannoproteins in significant amounts, could make these yeasts particularly interesting also for the industrial production of exogenous polysaccharide preparations.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Domizio P, Liu Y, Bisson LF, Barile D","authors_abbrev":"Domizio P et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"Food Microbiol 2017 Feb;61:136-149","cv_annotations":{},"doi":"10.1016/j.fm.2016.08.010","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2017","pubmed_entrez_date":"2016-10-05","pubmed_publication_date":"Feb 2017","terms_by_termid":{},"title":"Cell wall polysaccharides released during the alcoholic fermentation by Schizosaccharomyces pombe and S. japonicus: quantification and characterization.","uniquename":"PMID:27697163"}

  {"abstract":"DNA damage response includes DNA repair, nucleotide metabolism and even a control of cell fates including differentiation, cell death pathway or some combination of these. The responses to DNA damage differ from species to species. Here we aim to delineate the checkpoint pathway in the dimorphic fission yeast Schizosaccharomyces japonicus, where DNA damage can trigger a differentiation pathway that is a switch from a bidirectional yeast growth mode to an apical hyphal growth mode, and the switching is regulated via a checkpoint kinase, Chk1. This Chk1-dependent switch to hyphal growth is activated with even low doses of agents that damage DNA; therefore, we reasoned that this switch may depend on other genes orthologous to the components of the classical Sz. pombe Chk1-dependent DNA checkpoint pathway. As an initial test of this hypothesis, we assessed the effects of mutations in Sz. japonicus orthologs of Sz. pombe checkpoint genes on this switch from bidirectional to hyphal growth. The same set of DNA checkpoint genes was confirmed in Sz. japonicus. We tested the effect of each DNA checkpoint mutants on hyphal differentiation by DNA damage. We found that the Sz. japonicus hyphal differentiation pathway was dependent on Sz. japonicus orthologs of Sz. pombe checkpoint genes-(SP)rad3, (SP)rad26, (SP)rad9, (SP)rad1, (SP)rad24, (SP)rad25, (SP)crb2, and (SP)chk1-that function in the DNA damage checkpoint pathway, but was not dependent on orthologs of two Sz. pombe genes-(SP)cds1 or (SP)mrc1-that function in the DNA replication checkpoint pathway. These findings indicated that although the role of each component of the DNA damage checkpoint and DNA replication checkpoint is mostly same between the two fission yeasts, the DNA damage checkpoint was the only pathway that governed DNA damage-dependent hyphal growth. We also examined whether DNA damage checkpoint signaling engaged in functional crosstalk with other hyphal differentiation pathways because hyphal differentiation can also be triggered by nutritional stress. Here, we discovered genetic interactions that indicated that the cAMP pathway engaged in crosstalk with Chk1-dependent signaling.","alleles_by_uniquename":{"SJAG_00364:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00364","name":"rad3delta","uniquename":"SJAG_00364:allele-1"},"SJAG_00429:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00429","name":"rad26delta","uniquename":"SJAG_00429:allele-1"},"SJAG_01205:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01205","name":"crb2delta","uniquename":"SJAG_01205:allele-1"},"SJAG_01605:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01605","name":"rad9delta","uniquename":"SJAG_01605:allele-1"},"SJAG_01680:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01680","name":"chk1delta","uniquename":"SJAG_01680:allele-1"},"SJAG_01680:allele-2":{"allele_type":"amino_acid_mutation","description":"P470L","gene_uniquename":"SJAG_01680","name":"chk1-P470L","synonyms":[{"name":"chk1-

  {"abstract":"The structure and localization of the microtubule organization centres (MTOCs) of the fission yeast Schizosaccharomyces japonicus var. japonicus were examined by fluorescence microscopy and electron microscopy. Spindle pole bodies (SPBs), which are the fungal equivalent of centrosomes, of Sz. japonicus were visualized by immunofluorescent staining using a monoclonal anti-gamma-tubulin antibody. The behaviour of the SPBs during the cell cycle mostly coincided with previous reports on the most widely used fission yeast Schizosaccharomyces pombe. We cloned the gamma-tubulin gene from Sz. japonicus by PCR using redundant sets of primers corresponding to conserved regions of known gamma-tubulins. The predicted amino acid sequence of Sz. japonicus gamma-tubulin was most similar to the Sz. pombe gamma-tubulin. Under the electron microscope, the SPBs of Sz. japonicus were detected as electron-dense multilayered structures located just outside the nuclear envelope. The SPBs of Sz. japonicus were composed of three electron-dense layers and were surrounded by fuzzy material. Each layer showed structural changes according to the progression of the cell cycle. In mitotic cells, the SPBs were located on the fenestrae of the nuclear envelopes through which the mitotic spindle microtubules ran into the nucleoplasm. Our results show that Sz. japonicus is a very potent and attractive organism for the investigation of the microtubule nucleation system and morphogenesis in yeasts.

  {"abstract":"Schizosaccharomyces japonicus is a fission yeast for which new genetic tools have recently been developed. Here, we report novel plasmid vectors with high transformation efficiency and an electroporation method for Sz. japonicus. We isolated 44 replicating segments from 12 166 transformants of Sz. japonicus genomic fragments and found a chromosomal fragment, RS1, as a new replicating sequence that conferred high transformation activity to Sz. japonicus cells. This sequence was cloned into a pUC19 vector with ura4(+) of Sz. pombe (pSJU11) or the kan gene on the kanMX6 module (pSJK11) as selection markers. These plasmids transformed Sz. japonicus cells in the early-log phase by electroporation at a frequency of 123 cfu/µg for pSJK11 and 301 cfu/µg for pSJU11, which were higher than previously reported autonomously replicating sequences. Although a portion of plasmids remained in host cells by integration into the chromosome via RS1 segment, the plasmids could be recovered from transformants. The plasmid copy number was estimated to be 1.88 copies per cell by Southern blot analysis using a Sz. pombe ura4(+) probe. The plasmid containing ade6(+) suppressed the auxotrophic growth of the ade6-domE mutant, indicating that the plasmid would be useful for suppressor screening and complementation assays in Sz. japonicus. Furthermore, pSJU11 transformed Sz. pombe cells with the same frequency as the pREP2 plasmid.

In these organisms, tetrahymanol, formed through oxygen-independent cyclization of squalene by a squalene-tetrahymanol cyclase, acts as a sterol surrogate. This study confirms an early report [C. J. E. A. Bulder,  Antonie Van Leeuwenhoek , 37, 353-358 (1971)] that  Schizosaccharomyces japonicus  is exceptional among yeasts in growing anaerobically on synthetic media lacking sterols and unsaturated fatty acids. Mass spectrometry of lipid fractions of anaerobically grown  Sch. japonicus  showed the presence of hopanoids, a class of cyclic triterpenoids not previously detected in yeasts, including hop-22(29)-ene, hop-17(21)-ene, hop-21(22)-ene, and hopan-22-ol. A putative gene in  Sch. japonicus  showed high similarity to bacterial squalene-hopene cyclase (SHC) genes and in particular to those of  Acetobacter  species. No orthologs of the putative  Sch. japonicus  SHC were found in other yeast species. Expression of the  Sch. japonicus  SHC gene ( Sjshc1 ) in  Saccharomyces cerevisiae  enabled hopanoid synthesis and stimulated anaerobic growth in sterol-free media, thus indicating that one or more of the hopanoids produced by SjShc1 could at least partially replace sterols. Use of hopanoids as sterol surrogates represents a previously unknown adaptation of eukaryotic cells to anaerobic growth. The fast anaerobic growth of  Sch. japonicus  in sterol-free media is an interesting trait for developing robust fungal cell factories for application in anaerobic industrial processes.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Bouwknegt J, Wiersma SJ, Ortiz-Merino RA, Doornenbal ESR, Buitenhuis P, Giera M, Müller C, Pronk JT","authors_abbrev":"Bouwknegt J et al.","canto_added_date":"2023-05-04 00:40:04","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"Proc Natl Acad Sci U S A 2021 Aug 10;118(32)","cv_annotations":{},"doi":"10.1073/pnas.2105225118","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2021","pubmed_entrez_date":"2021-08-06","pubmed_publication_date":"10 Aug 2021","terms_by_termid":{},"title":"A squalene-hopene cyclase in  Schizosaccharomyces japonicus  represents a eukaryotic adaptation to sterol-limited anaerobic environments.","uniquename":"PMID:34353908"}

To overcome these problems, the aim of this study was to develop technical modifications which allow production of homogenous mycelial biomass without extra stimuli agents and improve quality of the RNA extracted from the fungal hyphae. Our alternative culture medium was suitable for production both yeast-phase cells and hyphae of the Schizosaccharomyces japonicus and other dimorphic species, such as the Candida albicans, Saccharomyces cerevisiae, and Jaminaea angkorensis. To improve quality of the mycelial RNA, we developed an isolation procedure of the hyphal tip, which eliminated the unnecessary vacuoles-containing parts of the hyphae. To increase RNA quantity, we used glass beads in the RNA extraction protocol to achieve stronger breaking of the mycelial walls.

Using single-molecule deep sequencing to construct amplification-free high-resolution replication profiles, we located origins and identified sequence motifs that predict origin function. We then mapped nucleosome occupancy by deep sequencing of mononucleosomal DNA from the corresponding species, finding that origins tend to occupy nucleosome-depleted regions.\nThe sequences that specify origins are evolutionarily plastic, with low complexity nucleosome-excluding sequences functioning in S. pombe and S. octosporus, and binding sites for trans-acting nucleosome-excluding proteins functioning in S. japonicus. Furthermore, chromosome-scale variation in replication timing is conserved independently of origin location and via a mechanism distinct from known heterochromatic effects on origin function. These results are consistent with a model in which origins are simply the nucleosome-depleted regions of the genome with the highest affinity for the origin recognition complex.

  {"abstract":"We previously demonstrated that we could hijack the fungal pheromone signaling pathway to provide a living yeast biosensor where peptide biomarkers were recognized by G-protein-coupled receptors and engineered to transcribe a readout. Here, we demonstrated that the protease could be reintroduced to the biosensor to provide a simple mechanism for distinguishing single-amino-acid changes in peptide ligands that, otherwise, would likely be difficult to detect using binding-based assays. We characterized the dose-response curves for five fungal pheromone G-protein-coupled receptors, peptides, and proteases -Saccharomyces cerevisiae ,  Candida albicans ,  Schizosaccharomyces pombe ,  Schizosaccharomyces octosporus , and  Schizosaccharomyces japonicus . Alanine scanning was carried out for the most selective of these- S. cerevisiae  and  C. albicans -with and without the protease. Two peptide variants were discovered, which showed diminished cleavage by the protease (CaPep2A and CaPep2A13A). Those peptides were then distinguished by utilizing the biosensor strains with and without the protease, which selectively cleaved and altered the apparent concentration of peptide required for half-maximal activation for 2 peptides-CaPep and CaPep13A, respectively-by more than one order of magnitude. These results support the hypothesis that the living yeast biosensor with a sequence-specific protease can translate single-amino-acid changes into more than one order of magnitude apparent shift in the concentration of peptide required for half-maximal activation. With further engineering by computational modeling and directed evolution, the biosensor could likely distinguish a wide variety of peptide sequences beyond the alanine scanning carried out here. In the future, we envision incorporating proteases into our living yeast biosensor for use as a point of care diagnostic, a scalable communication language, and other applications.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Crnković T, Bokor BJ, Lockwood ME, Cornish VW","authors_abbrev":"Crnković T et al.","canto_added_date":"2023-10-19 00:40:03","canto_curator_role":"JaponicusDB","canto_triage_status":"Method or reagent","citation":"Biodes Res 2023;5:0003","cv_annotations":{},"doi":"10.34133/bdr.0003","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2023","pubmed_entrez_date":"2023-10-18","pubmed_publication_date":"2023","terms_by_termid":{},"title":"Peptide Variant Detection by a Living Yeast Biosensor via an Epitope-Selective Protease.","uniquename":"PMID:37849458"}

Therefore, studying the biosynthesis of CoQ10 is important not only for increasing metabolic knowledge, but also for improving biotechnological production. Herein, we show that Schizosaccharomyces pombe utilizes p-aminobenzoate (PABA) in addition to p-hydroxybenzoate (PHB) as a precursor for CoQ10 synthesis. We explored compounds that affect the synthesis of CoQ10 and found benzoic acid (Bz) at >5 μg/mL inhibited CoQ biosynthesis without accumulation of apparent CoQ intermediates. This inhibition was counteracted by incubation with a 10-fold lower amount of PABA or PHB. Overexpression of PHB-polyprenyl transferase encoded by ppt1 (coq2) also overcame the inhibition of CoQ biosynthesis by Bz. Inhibition by Bz was efficient in S. pombe and Schizosaccharomyces japonicus, but less so in Saccharomyces cerevisiae, Aureobasidium pullulans, and Escherichia coli. Bz also inhibited a S. pombe ppt1 (coq2) deletion strain expressing human COQ2, and this strain also utilized PABA as a precursor of CoQ10.

The fluorescence images obtained with S. japonicus were markedly superior to those previously reported for S. pombe and revealed new details of cytoskeletal organization in this important genus. As in S. pombe, F-actin in S. japonicus was present as a concentration of 'dots' at the growing poles of interphase cells and as a filamentous equatorial ring directing the deposition of the cytokinetic septum. The transition between these two states occurred at late anaphase, in contrast to the situation in S. pombe where the appearance of the equatorial actin ring is tightly coupled to the early events of mitosis. During the course of cytokinesis in S. japonicus the actin ring constricted and broadened, suggesting that it is contractile. Microtubule organization in S. japonicus also revealed interesting differences from S. pombe. Whereas in S. pombe cytoplasmic microtubules are reinitiated from a pair of microtubule organizing centres (MTOCs) at the cell equator, in S. japonicus they arise by extensive microtubule growth from the spindle poles. Western blots of cell extracts enriched for tubulin by DEAE-Sephadex chromatography showed that, like S. pombe, S. japonicus contains two alpha-tubulins and a single beta-tubulin. Whilst the alpha 1- and beta-tubulins from the two species comigrated on one-dimensional polyacrylamide gels, the alpha 2 species were electrophoretically distinct.

  {"abstract":"A key question in developmental biology addresses the mechanism of asymmetric cell division. Asymmetry is crucial for generating cellular diversity required for development in multicellular organisms. As one of the potential mechanisms, chromosomally borne epigenetic difference between sister cells that changes mating/cell type has been demonstrated only in the Schizosaccharomyces pombe fission yeast. For technical reasons, it is nearly impossible to determine the existence of such a mechanism operating during embryonic development of multicellular organisms. Our work addresses whether such an epigenetic mechanism causes asymmetric cell division in the recently sequenced fission yeast, S. japonicus (with 36% GC content), which is highly diverged from the well-studied S. pombe species (with 44% GC content). We find that the genomic location and DNA sequences of the mating-type loci of S. japonicus differ vastly from those of the S. pombe species. Remarkably however, similar to S. pombe, the S. japonicus cells switch cell/mating type after undergoing two consecutive cycles of asymmetric cell divisions: only one among four \"granddaughter\" cells switches. The DNA-strand-specific epigenetic imprint at the mating-type locus1 initiates the recombination event, which is required for cellular differentiation. Therefore the S. pombe and S. japonicus mating systems provide the first two examples in which the intrinsic chirality of double helical structure of DNA forms the primary determinant of asymmetric cell division. Our results show that this unique strand-specific imprinting/segregation epigenetic mechanism for asymmetric cell division is evolutionary conserved. Motivated by these findings, we speculate that DNA-strand-specific epigenetic mechanisms might have evolved to dictate asymmetric cell division in diploid, higher eukaryotes as well.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Yu C, Bonaduce MJ, Klar AJ","authors_abbrev":"Yu C et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"Genetics 2013 Jan;193(1):85-94","cv_annotations":{},"doi":"10.1534/genetics.112.146233","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2013","pubmed_entrez_date":"2012-11-15","pubmed_publication_date":"Jan 2013","terms_by_termid":{},"title":"Defining the epigenetic mechanism of asymmetric cell division of Schizosaccharomyces japonicus yeast.","uniquename":"PMID:23150598"}

  {"abstract":"The fission yeast Schizosaccharomyces pombe shows bipolar growth and is a convenient model for studying cell polarity and polar growth. This paper shows that the related Schiz. japonicus var. japonicus can switch to unipolar growth and can exist in both yeast and mycelial phases. On solid media, the yeast phase is unstable and prone to switch to the mycelial form, which shows unipolar growth by tip elongation. The hyphae can colonize the body of the substrate (true mycelium) or just its surface (pseudo-mycelium). The yeast-to-mycelium transition and the growth of the mycelium are regulated by a nutritional gradient and are associated with extensive vacuolation. The mycelium can convert into arthroconidia or return to the yeast phase in response to environmental changes. These environmentally controlled morphological transitions make Schiz. japonicus var. japonicus an attractive model for the investigation of cell polarity and morphogenesis.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2021-10-07","authors":"Sipiczki M, Takeo K, Yamaguchi M, Yoshida S, Miklos I","authors_abbrev":"Sipiczki M et al.","canto_added_date":"2021-09-30 08:50:02","canto_annotation_status":"APPROVED","canto_approved_date":"2021-10-07 12:30:26","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2021-10-07 12:30:26","canto_session_key":"fced61f1377cd206","canto_session_submitted_date":"2021-09-30 08:52:46","canto_triage_status":"Curatable","citation":"Microbiology (Reading) 1998 May;144 ( Pt 5):1319-1330","cv_annotations":{},"doi":"10.1099/00221287-144-5-1319","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"1998","pubmed_entrez_date":"1998-06-05","pubmed_publication_date":"May 1998","terms_by_termid":{},"title":"Environmentally controlled dimorphic cycle in a fission yeast.","uniquename":"PMID:9611807"}

  {"abstract":"The fission yeast Schizosaccharomyces japonicus var. japonicus belong to the genus Schizosaccharomyces, together with Schizosaccharomyces pombe, which has been well studied as a model organism. In contrast, Sz. japonicus is poorly characterized and genetic tools were yet to be developed. We here report the isolation of the heterothallic haploids NIG2017, NIG2025 and NIG2028, which were derivatives of a Sz. japonicus homothallic strain (NIG2008). Based on the genomic sequence of Sz. japonicus, released by the Broad Institute, we found that Sz. japonicus also possesses orthologues of the mating-type genes of Sz. pombe; two mat-M (-) and two mat-P (+) genes. As expected, heterothallic strains were defective in one of the Sz. japonicus mat genes (mat(sj)). We confirmed that NIG2017 and NIG2025 strains only expressed mRNA from the mat(sj)-P genes, while homothallic strains expressed both mat(sj)-M and mat(sj)-P. Although the NIG2028 strain expressed both gene products, mat(sj)-P was found mutated, which may have conferred the heterothallic phenotype of the mutant. Thus, we concluded that these were stable heterothallic strains. We designated NIG2017 and NIG2025 as h(+) and NIG 2028 as h(-), respectively. We also found additional h(-) strains (NIG5872 and NIG5873) that arose from the cross between NIG2017 and NIG2028 derivatives. In addition to that, we have constructed a ura4(sj)-deleted strain and an ade6(sj)-mutated strain. We used these heterothallic strains and the auxotroph strains to perform spore dissection analysis to determine the genetic distances between several loci, and found that the mating type loci and ade6(sj) locus were linked to centromeres.","alleles_by_uniquename":{"SJAG_01081:allele-1":{"allele_type":"nonsense_mutation","description":"S427>stop","gene_uniquename":"SJAG_01081","name":"ade6-domE","uniquename":"SJAG_01081:allele-1"},"SJAG_03164:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03164","name":"ura4delta","uniquename":"SJAG_03164:allele-1"}},"annotation_curators":[{"annotation_count":2,"community_curator":true,"file_name":null,"file_type":null,"name":"Sho Okamoto","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-11-23","authors":"Furuya K, Niki H","authors_abbrev":"Furuya K et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2022-11-23 13:08:27","canto_curator_name":"Sho Okamoto","canto_curator_role":"community","canto_first_approved_date":"2022-11-23 13:08:26","canto_session_key":"386d294cfcac2a63","canto_session_submitted_date":"2022-11-23 13:07:46","canto_triage_status":"Curatable","citation":"Yeast 2009 Apr;26(4):221-33","cv_annotations":{"single_locus_phenotype":[{"annotations":[114466],"is_not":false,"summary":null,"term":"FYPO:0000747"},{"annotations":[114467],"is_not":false,"summary":null,"term":"FYPO:0001012"}]},"doi":"10.1002/yea.1662","gene_count":2,"genes_by_uniquename":{"SJAG_01081":null,"SJAG_03164":null},"genotypes_by_uniquename":{"ade6-domE-S427>stop-nonsense_mutation-expression-not_assayed_or_wild_type":{"display_name":"ade6-domE(S427>stop)","display_uniquename":"ade6-domE-S427>stop-nonsense_mutation-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01081:allele-1","expression":"Not assayed or wild type"}]}]},"ura4delta":{"display_name":"ura4delta","display_uniquename":"ura4delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_03164:allele-1","expression":"Null"}]}]}},"ltp_gene_count":2,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2009","pubmed_entrez_date":"2009-03-31","pubmed_publication_date":"Apr 2009","terms_by_termid":{"FYPO:0000747":null,"FYPO:0001012":null},"title":"Isolation of heterothallic haploid and auxotrophic mutants of Schizosaccharomyces japonicus.","uniquename":"PMID:19330769"}

  {"abstract":"Many fungal species are dimorphic, exhibiting both unicellular yeast-like and filamentous forms. Schizosaccharomyces japonicus, a member of the fission yeast clade, is one such dimorphic fungus. Here, we first identify fruit extracts as natural, stress-free, starvation-independent inducers of filamentation, which we use to describe the properties of the dimorphic switch. During the yeast-to-hypha transition, the cell evolves from a bipolar to a unipolar system with 10-fold accelerated polarized growth but constant width, vacuoles segregated to the nongrowing half of the cell, and hyper-lengthening of the cell. We demonstrate unusual features of S. japonicus hyphae: these cells lack a Spitzenkörper, a vesicle distribution center at the hyphal tip, but display more rapid cytoskeleton-based transport than the yeast form, with actin cables being essential for the transition. S. japonicus hyphae also remain mononuclear and undergo complete cell divisions, which are highly asymmetric: one daughter cell inherits the vacuole, the other the growing tip. We show that these elongated cells scale their nuclear size, spindle length, and elongation rates, but display altered division size controls. This establishes S. japonicus as a unique system that switches between symmetric and asymmetric modes of growth and division.","alleles_by_uniquename":{"SJAG_02392:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02392","name":"pom1delta","uniquename":"SJAG_02392:allele-1"},"SJAG_02695:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02695","name":"tip1delta","uniquename":"SJAG_02695:allele-1"},"SJAG_04703:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04703","name":"for3delta","uniquename":"SJAG_04703:allele-1"}},"annotation_curators":[{"annotation_count":21,"community_curator":true,"file_name":null,"file_type":null,"name":"Sophie Martin","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2021-06-16","authors":"Kinnaer C, Dudin O, Martin SG","authors_abbrev":"Kinnaer C et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2021-06-16 18:49:31","canto_curator_name":"Sophie Martin","canto_curator_role":"community","canto_first_approved_date":"2021-06-16 18:49:31","canto_session_key":"bf05a60cb09b4cdb","canto_session_submitted_date":"2021-06-04 10:25:08","canto_triage_status":"Curatable","citation":"Mol Biol Cell 2019 04 01;30(8):975-991","cv_annotations":{"cellular_component":[{"annotations":[114486],"is_not":false,"summary":null,"term":"GO:0051286"},{"annotations":[114468,114470,114472,114474,114476,114478],"is_not":false,"summary":null,"term":"GO:0035838"},{"annotations":[114487],"is_not":false,"summary":null,"term":"GO:0085039"},{"annotations":[114469,114471,114473,114475,114477,114479],"is_not":false,"summary":null,"term":"GO:0001411"},{"annotations":[114480],"is_not":false,"summary":null,"term":"GO:0035371"},{"annotations":[114481],"is_not":false,"summary":null,"term":"GO:0030133"}],"single_locus_phenotype":[{"annotations":[114483],"is_not":false,"summary":null,"term":"FYPO:0003315"},{"annotations":[114484],"is_not":false,"summary":null,"term":"FYPO:0001355"},{"annotations":[114488],"is_not":false,"summary":null,"term":"FYPO:0007801"},{"annotations":[114485],"is_not":false,"summary":null,"term":"FYPO:0004293"},{"annotations":[114482],"is_not":false,"summary":null,"term":"FYPO:0001956"}]},"doi":"10.1091/mbc.E18-12-0774","gene_count":9,"genes_by_uniquename":{"SJAG_01196":null,"SJAG_02392":null,"SJAG_02695":null,"SJAG_03011":null,"SJAG_03625":null,"SJAG_03915":null,"SJAG_04624":null,"SJAG_04703":null,"SJAG_04960":null},"genotypes_by_uniquename":{"for3delta":{"display_name":"for3delta","display_uniquename":"for3delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_04703:allele-1","expression":"Null"}]}]},"pom1delta":{"display_name":"pom1delta","display_uniquename":"pom1delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_02392:allele-1","expression":"Null"}]}]},"tip1delta":{"display_name":"tip1delta","display_uniquename":"tip1delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_02695:allele-1","expression":"Null"}]}]}},"ltp_gene_count":9,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2019","pubmed_entrez_date":"2019-02-07","pubmed_publication_date":"01 04 2019","terms_by_termid":{"FYPO:0001355":null,"FYPO:0001956":null,"FYPO:0003315":null,"FYPO:0004293":null,"FYPO:0007801":null,"GO:0001411":null,"GO:0030133":null,"GO:0035371":null,"GO:0035838":null,"GO:0051286":null,"GO:0085039":null},"title":"Yeast-to-hypha transition of Schizosaccharomyces japonicus in response to environmental stimuli.","uniquename":"PMID:30726171"}

  {"abstract":"RNA interference (RNAi) is a conserved mechanism of small RNA-mediated genome regulation commonly involved in suppression of transposable elements (TEs) through both post-transcriptional silencing, and transcriptional repression via heterochromatin assembly. The fission yeast Schizosaccharomyces pombe has been extensively utilised as a model for studying RNAi pathways. However, this species is somewhat atypical in that TEs are not major targets of RNAi, and instead small RNAs correspond primarily to non-coding pericentromeric repeat sequences, reflecting a specialised role for the pathway in promoting heterochromatin assembly in these regions. In contrast, in the related fission yeast Schizosaccharomyces japonicus, sequenced small RNAs correspond primarily to TEs. This suggests there may be fundamental differences in the operation of RNAi pathways in these two related species. To investigate these differences, we probed RNAi function in S. japonicus. Unexpectedly, and in contrast to S. pombe, we found that RNAi is essential in this species. Moreover, viability of RNAi mutants can be rescued by mutations implicated in enhancing RNAi-independent heterochromatin propagation. These rescued strains retain heterochromatic marks on TE sequences, but exhibit derepression of TEs at the post-transcriptional level. Our findings indicate that S. japonicus retains the ancestral role of RNAi in facilitating suppression of TEs via both post-transcriptional silencing and heterochromatin assembly, with specifically the heterochromatin pathway being essential for viability, likely due to a function in genome maintenance. The specialised role of RNAi in heterochromatin assembly in S. pombe appears to be a derived state that emerged after the divergence of S. japonicus.","alleles_by_uniquename":{"SJAG_02409:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02409","name":"stc1delta","uniquename":"SJAG_02409:allele-1"},"SJAG_02594:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02594","name":"arb1delta","uniquename":"SJAG_02594:allele-1"},"SJAG_02621:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02621","name":"ago1delta","uniquename":"SJAG_02621:allele-1"},"SJAG_02668:allele-1":{"allele_type":"amino_acid_mutation","description":"R77W","gene_uniquename":"SJAG_02668","name":"mpe1-R77W","uniquename":"SJAG_02668:allele-1"},"SJAG_03118:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03118","name":"leo1delta","uniquename":"SJAG_03118:allele-1"},"SJAG_03118:allele-2":{"allele_type":"nonsense_mutation","description":"aa61->stop","gene_uniquename":"SJAG_03118","name":"frameshift","uniquename":"SJAG_03118:allele-2"},"SJAG_03356:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03356","name":"rdp1delta","uniquename":"SJAG_03356:allele-1"},"SJAG_03689:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03689","name":"dcr1delta","uniquename":"SJAG_03689:allele-1"},"SJAG_03916:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03916","name":"chp1delta","uniquename":"SJAG_03916:allele-1"},"SJAG_04061:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04061","name":"arb2delta","uniquename":"SJAG_04061:allele-1"},"SJAG_04574:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04574","name":"clr4delta","uniquename":"SJAG_04574:allele-1"}},"annotation_curators":[{"annotation_count":31,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana

  {"abstract":"In the fission yeast Schizosaccharomyces pombe (Sp), Mid1/Dmf1 plays an important role in positioning the division site by inducing formation of the contractile ring (CR). Mid1, emanating from the nucleus located in the cell center, forms a dozen of nodes in the middle cell cortex ahead of mitosis, and actin filaments and myosin II accumulated at each node interact and assemble the CR in metaphase. Curiously, in another fission yeast S. japonicus (Sj), CR formation begins after nuclear segregation in late anaphase. Here, we investigated the role of S. japonicus Mid1 during mitosis to compare the molecular mechanisms that determine the cell division site in Schizosaccharomyces. Similar to Sp Mid1, Sj Mid1 often accumulated in the nucleus of interphase cells. Moreover, Sj Mid1 localized to cortical dots with myosin II in the future division site and formed a medial ring in mitotic cells. However, S. japonicus cells without Mid1 function still carried out symmetrical binary division.

  {"abstract":"Eukaryotes remodel the nucleus during mitosis using a variety of mechanisms that differ in the timing and the extent of nuclear envelope (NE) breakdown. Here, we probe the principles enabling this functional diversity by exploiting the natural divergence in NE management strategies between the related fission yeasts Schizosaccharomyces pombe and Schizosaccharomyces japonicus [1-3]. We show that inactivation of Ned1, the phosphatidic acid phosphatase of the lipin family, by CDK phosphorylation is both necessary and sufficient to promote NE expansion required for \"closed\" mitosis in S. pombe. In contrast, Ned1 is not regulated during division in S. japonicus, thus limiting membrane availability and necessitating NE breakage. Interspecies gene swaps result in phenotypically normal divisions with the S. japonicus lipin acquiring an S. pombe-like mitotic phosphorylation pattern. Our results provide experimental evidence for the mitotic regulation of phosphatidic acid flux and suggest that the regulatory networks governing lipin activity diverged in evolution to give rise to strikingly dissimilar mitotic programs.

  {"abstract":"Most eukaryotes respire oxygen, using it to generate biomass and energy. However, a few organisms have lost the capacity to respire. Understanding how they manage biomass and energy production may illuminate the critical points at which respiration feeds into central carbon metabolism and explain possible routes to its optimization. Here, we use two related fission yeasts, Schizosaccharomyces pombe and Schizosaccharomyces japonicus, as a comparative model system. We show that although S. japonicus does not respire oxygen, unlike S. pombe, it is capable of efficient NADH oxidation, amino acid synthesis, and ATP generation. We probe possible optimization strategies through the use of stable isotope tracing metabolomics, mass isotopologue distribution analysis, genetics, and physiological experiments. S. japonicus appears to have optimized cytosolic NADH oxidation via glycerol-3-phosphate synthesis. It runs a fully bifurcated TCA pathway, sustaining amino acid production. Finally, we propose that it has optimized glycolysis to maintain high ATP/ADP ratio, in part by using the pentose phosphate pathway as a glycolytic shunt, reducing allosteric inhibition of glycolysis and supporting biomass generation. By comparing two related organisms with vastly different metabolic strategies, our work highlights the versatility and plasticity of central carbon metabolism in eukaryotes, illuminating critical adaptations supporting the preferential use of glycolysis over oxidative phosphorylation.","alleles_by_uniquename":{"SJAG_00409:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00409","name":"gpd1delta","uniquename":"SJAG_00409:allele-1"},"SJAG_00601:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00601","name":"rip1delta","uniquename":"SJAG_00601:allele-1"},"SJAG_01355:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01355","name":"cox6delta","uniquename":"SJAG_01355:allele-1"},"SJAG_01753:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01753","name":"mdh1delta","uniquename":"SJAG_01753:allele-1"},"SJAG_02796:allele-1":{"allele_type":"amino_acid_mutation","description":"A343T","gene_uniquename":"SJAG_02796","name":"pyk1-A343T","uniquename":"SJAG_02796:allele-1"},"SJAG_03920:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03920","name":"sdh3delta","uniquename":"SJAG_03920:allele-1"},"SJAG_04843:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04843","name":"fum1delta","uniquename":"SJAG_04843:allele-1"}},"annotation_curators":[{"annotation_count":20,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana

  {"abstract":"Meiotic prophase in Schizosaccharomyces pombe is characterized by striking nuclear movements and the formation of linear elements along chromosomes instead of tripartite synaptonemal complexes. We analysed the organization of nuclei and microtubules in cells of fission yeasts undergoing sexual differentiation. S. japonicus var. versatilis and S. pombe cells were studied in parallel, taking advantage of the better cytology in S. versatilis. During conjugation, microtubules were directed towards the mating projection. These microtubules seem to lead the haploid nuclei together in the zygote by interaction with the spindle pole bodies at the nuclear periphery. After karyogamy, arrays of microtubules emanating from the spindle pole body of the diploid nucleus extended to both cell poles. The same differentiated microtubule configuration was elaborated upon induction of azygotic meiosis in S. pombe. The cyclic movements of the elongated nuclei between the cell poles is reflected by a dynamic and coordinated shortening and lengthening of the two microtubule arrays. When the nucleus was at a cell end, one array was short while the other bridged the whole cell length. Experiments with inhibitors showed that microtubules are required for karyogamy and for the elongated shape and movement of nuclei during meiotic prophase. In both fission yeasts the SPBs and nucleoli are at the leading ends of the moving nuclei. Astral and cytoplasmic microtubules were also prominent during meiotic divisions and sporulation. We further show that in S. versatilis the linear elements formed during meiotic prophase are similar to those in S. pombe. Tripartite synaptonemal complexes were never detected. Taken together, these findings suggest that S. pombe and S. versatilis share basic characteristics in the organization of microtubules and the structure and behaviour of nuclei during their meiotic cell cycle. The prominent differentiations of microtubules and nuclei may be involved in the pairing, recombination, and segregation of meiotic chromosomes.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Svoboda A, Bähler J, Kohli J","authors_abbrev":"Svoboda A et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"Chromosoma 1995 Nov;104(3):203-14","cv_annotations":{},"gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"1995","pubmed_entrez_date":"1995-11-01","pubmed_publication_date":"Nov 1995","terms_by_termid":{},"title":"Microtubule-driven nuclear movements and linear elements as meiosis-specific characteristics of the fission yeasts Schizosaccharomyces versatilis and Schizosaccharomyces pombe.","uniquename":"PMID:8529460"}

How chromatin tethering to the INM is controlled in interphase and how this process contributes to subsequent mitotic nuclear envelope (NE) remodeling remains unclear. We have probed these fundamental questions using the fission yeast Schizosaccharomyces japonicus, which breaks and reforms the NE during mitosis. We show that attachments between heterochromatin and the transmembrane Lem2-Nur1 complex at the INM are remodeled in interphase by the ESCRT-III/Vps4 machinery. Failure of ESCRT-III/Vps4 to release Lem2-Nur1 from heterochromatin leads to persistent association of chromosomes with the INM throughout mitosis. At mitotic exit, such trapping of Lem2-Nur1 on heterochromatin prevents it from re-establishing nucleocytoplasmic compartmentalization. Our work identifies the Lem2-Nur1 complex as a substrate for the nuclear ESCRT machinery and explains how the dynamic tethering of chromosomes to the INM is linked to the establishment of nuclear compartmentalization.","alleles_by_uniquename":{"SJAG_01050:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01050","name":"nur1delta","uniquename":"SJAG_01050:allele-1"},"SJAG_01242:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01242","name":"vps32delta","uniquename":"SJAG_01242:allele-1"},"SJAG_01330:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01330","name":"mad2delta","uniquename":"SJAG_01330:allele-1"},"SJAG_01745:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01745","name":"lem2delta","uniquename":"SJAG_01745:allele-1"},"SJAG_03250:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03250","name":"sst4delta","uniquename":"SJAG_03250:allele-1"},"SJAG_03783:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03783","name":"vps24delta","uniquename":"SJAG_03783:allele-1"},"SJAG_03892:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03892","name":"vps4delta","uniquename":"SJAG_03892:allele-1"},"SJAG_03892:allele-2":{"allele_type":"amino_acid_mutation","description":"E233Q","gene_uniquename":"SJAG_03892","name":"Vps4-EQ","uniquename":"SJAG_03892:allele-2"},"SJAG_03892:allele-3":{"allele_type":"amino_acid_mutation","description":"I307T

  {"abstract":"The nuclear envelope (NE) undergoes dynamic remodeling to maintain NE integrity, a process involving the inner nuclear membrane protein LEM2 recruiting CHMP7/Cmp7 and then ESCRT-III. However, prior work has hinted at CHMP7/ESCRT-independent mechanisms. To identify such mechanisms, we studied NE assembly in Schizosaccharomyces japonicus, a fission yeast that undergoes partial mitotic NE breakdown and reassembly. S. japonicus cells lacking Cmp7 have compromised NE sealing after mitosis but are viable. A genetic screen identified mutations that promote NE integrity in cmp7Δ cells. Unexpectedly, loss of Lem2 or its interacting partner Nur1 suppressed cmp7Δ defects. In the absence of Cmp7, Lem2 formed aggregates that appear to interfere with ESCRT-independent NE sealing. A gain-of-function mutation implicated a membrane and ESCRT-III regulator, Alx1, in this alternate pathway. Additional results suggest a potentially general role for unsaturated fatty acids in NE integrity. These findings establish the existence of mechanisms for NE sealing independent of the canonical ESCRT pathway.","alleles_by_uniquename":{"SJAG_01242:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01242","name":"vps32delta","uniquename":"SJAG_01242:allele-1"},"SJAG_01745:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01745","name":"lem2delta","uniquename":"SJAG_01745:allele-1"},"SJAG_03891:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03891","name":"alx1delta","uniquename":"SJAG_03891:allele-1"},"SJAG_05207:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_05207","name":"cmp7delta","uniquename":"SJAG_05207:allele-1"}},"annotation_curators":[{"annotation_count":21,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana

  {"abstract":"Many fungi respond to light and regulate fungal development and behavior. A blue light-activated complex has been identified in Neurospora crassa as the product of the wc-1 and wc-2 genes. Orthologs of WC-1 and WC-2 have hitherto been found only in filamentous fungi and not in yeast, with the exception of the basidiomycete pathogenic yeast Cryptococcus. Here, we report that the fission yeast Schizosaccharomyces japonicus responds to blue light depending on Wcs1 and Wcs2, orthologs of components of the WC complex. Surprisingly, those of ascomycete S. japonicus are more closely related to those of the basidiomycete. S. japonicus reversibly changes from yeast to hyphae in response to environmental stresses. After incubation at 30°C, a colony of yeast was formed, and then hyphal cells extended from the periphery of the colony. When light cycles were applied, distinct dark- and bright-colored hyphal cell stripes were formed because the growing hyphal cells had synchronously activated cytokinesis. In addition, temperature cycles of 30°C for 12 h and 35°C for 12 h or of 25°C for 12 h and 30°C for 12 h during incubation in the dark induced a response in the hyphal cells similar to that of light.

  {"abstract":"During open mitosis in higher eukaryotic cells, the nuclear envelope completely breaks down and then mitotic chromosomes are exposed in the cytoplasm. By contrast, mitosis in lower eukaryotes, including fungi, proceeds with the nucleus enclosed in an intact nuclear envelope. The mechanism of mitosis has been studied extensively in yeast, a closed mitosis organism. Here, we describe a form of mitosis in which the nuclear envelope is torn by elongation of the nucleus in the fission yeast Schizosaccharomyces japonicus. The mitotic nucleus of Sz. japonicus adopted a fusiform shape in anaphase, and its following extension caused separation. Finally, a tear in the nuclear envelope occurred in late anaphase. At the same time, a polarized-biased localization of nuclear pores was seen in the fusiform-shaped nuclear envelope, suggesting a compromise in the mechanical integrity of the lipid membrane. It has been known that nuclear membrane remains intact in some metazoan mitosis. We found that a similar tear of the nuclear envelope was also observed in late mitosis of the Caenorhabditis elegans embryo. These findings provide insight into the diversity of mitosis and the biological significance of breakdown of the nuclear envelope.","alleles_by_uniquename":{},"annotation_curators":[{"annotation_count":2,"community_curator":true,"file_name":null,"file_type":null,"name":"Sho Okamoto","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-11-21","authors":"Aoki K, Hayashi H, Furuya K, Sato M, Takagi T, Osumi M, Kimura A, Niki H","authors_abbrev":"Aoki K et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2022-11-21 17:28:56","canto_curator_name":"Sho Okamoto","canto_curator_role":"community","canto_first_approved_date":"2022-11-21 17:28:56","canto_session_key":"6063f08db89b54c7","canto_session_submitted_date":"2022-11-21 17:28:46","canto_triage_status":"Curatable","citation":"Genes Cells 2011 Sep;16(9):911-26","cv_annotations":{"cellular_component":[{"annotations":[114344],"is_not":false,"summary":null,"term":"GO:0070762"},{"annotations":[114345],"is_not":false,"summary":null,"term":"GO:0005816"}]},"doi":"10.1111/j.1365-2443.2011.01540.x","gene_count":1,"genes_by_uniquename":{"SJAG_03200":null},"genotypes_by_uniquename":{},"ltp_gene_count":1,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2011","pubmed_entrez_date":"2011-07-08","pubmed_publication_date":"Sep 2011","terms_by_termid":{"GO:0005816":null,"GO:0070762":null},"title":"Breakage of the nuclear envelope by an extending mitotic nucleus occurs during anaphase in Schizosaccharomyces japonicus.","uniquename":"PMID:21733045"}

The ability of alkaloids to display primary fluorescence, allowed us to record their dynamics and localization in cells. Cytotoxic, anti-microtubular, and anti-actin effects in living cells were studied. In the yeasts, neither microtubules nor cell growth was seriously affected even at the alkaloid concentration of 100 microg/ml. The HeLa cells, however, responded to the toxic effect of alkaloids at concentrations ranging from 1 to 50 microg/ml. IC50 values for individual alkaloids were: sanguinarine IC50 = 0.8 microg/ml, sanguilutine IC50 = 8.3 microg/ml, chelerythrine IC50 = 6.2 microg/ml, chelilutine IC50 = 5.2 microg/ml, coptisine IC50 = 2.6 microg/ml and berberine IC50 > 10.0 microg/ml. In living cells, sanguinarine produced a decrease in microtubule numbers, particularly at the cell periphery, at a concentration of 0.1 microg/ml. The other alkaloids showed a similar effect but at higher concentrations (5-50 microg/ml). The strongest effects of sanguinarine were explained as a consequence of its easy penetration through the cell membrane owing to nonpolar pseudobase formation and to a high degree of molecular planarity.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Slaninová I, Táborská E, Bochoráková H, Slanina J","authors_abbrev":"Slaninová I et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"Cell Biol Toxicol 2001;17(1):51-63","cv_annotations":{},"gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2001","pubmed_entrez_date":"2001-08-16","pubmed_publication_date":"2001","terms_by_termid":{},"title":"Interaction of benzo[c]phenanthridine and protoberberine alkaloids with animal and yeast cells.","uniquename":"PMID:11504450"}

  {"abstract":"Fission yeast cells grow by extension at the ends (poles) and divide by transverse fission. It has previously been reported that Schizosaccharomyces japonicus var. japonicus can switch to unipolar, filamentous growth. Here it is shown that the yeast-to-mycelium transition is a gradual process involving a changeover to unipolar growth associated with asymmetric divisions, the development of large polarly located vacuoles, the modifications of the actin and microtubular cytoskeleton and the repression of cell separation after division. High concentrations of glucose in the medium or supplementation of the medium with caffeine or cAMP support the bipolar yeast phase, inhibit the transition to the mycelial phase and induce the conversion of hyphae to yeasts. These effects suggest that cAMP may be involved in the regulation of dimorphism. Temperatures below 18 degrees C or over 35 degrees C are restrictive for the mycelial phase and provoke a return to yeast phase.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2021-10-07","authors":"Sipiczki M, Takeo K, Grallert A","authors_abbrev":"Sipiczki M et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2021-10-07 12:31:51","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2021-10-07 12:31:51","canto_session_key":"5ac54d09f220d215","canto_session_submitted_date":"2021-09-30 09:01:47","canto_triage_status":"Curatable","citation":"Microbiology (Reading) 1998 Dec;144 ( Pt 12):3475-3485","cv_annotations":{},"doi":"10.1099/00221287-144-12-3475","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"1998","pubmed_entrez_date":"1999-01-12","pubmed_publication_date":"Dec 1998","terms_by_termid":{},"title":"Growth polarity transitions in a dimorphic fission yeast.","uniquename":"PMID:9884240"}

In this regard, various yeast species are used as models in lipid metabolic research or for industrial lipid production. Lipid droplets are highly dynamic storage bodies and their cellular content represents a convenient readout of the lipid metabolic state. Fluorescence microscopy is a method of choice for quantitative analysis of cellular lipid droplets, as it relies on widely available equipment and allows analysis of individual lipid droplets. Furthermore, microscopic image analysis can be automated, greatly increasing overall analysis throughput. Here, we describe an experimental and analytical workflow for automated detection and quantitative description of individual lipid droplets in three different model yeast species: the fission yeasts Schizosaccharomyces pombe and Schizosaccharomyces japonicus, and the budding yeast Saccharomyces cerevisiae. Lipid droplets are visualized with BODIPY 493/503, and cell-impermeable fluorescent dextran is added to the culture media to help identify cell boundaries. Cells are subjected to 3D epifluorescence microscopy in green and blue channels and the resulting z-stack images are processed automatically by a MATLAB pipeline. The procedure outputs rich quantitative data on cellular lipid droplet content and individual lipid droplet characteristics in a tabular format suitable for downstream analyses in major spreadsheet or statistical packages.

  {"abstract":"Mitogen activated protein kinase (MAPK) signaling pathways execute essential functions in eukaryotic organisms by transducing extracellular stimuli into adaptive cellular responses. In the fission yeast model  Schizosaccharomyces pombe  the cell integrity pathway (CIP) and its core effector, MAPK Pmk1, play a key role during regulation of cell integrity, cytokinesis, and ionic homeostasis.  Schizosaccharomyces japonicus , another fission yeast species, shows remarkable differences with respect to  S. pombe , including a robust yeast to hyphae dimorphism in response to environmental changes. We show that the CIP MAPK module architecture and its upstream regulators, PKC orthologs Pck1 and Pck2, are conserved in both fission yeast species. However, some of  S. pombe 's CIP-related functions, such as cytokinetic control and response to glucose availability, are regulated differently in  S. japonicus.  Moreover, Pck1 and Pck2 antagonistically regulate  S. japonicus  hyphal differentiation through fine-tuning of Pmk1 activity. Chimeric MAPK-swapping experiments revealed that  S. japonicus  Pmk1 is fully functional in  S. pombe , whereas  S. pombe  Pmk1 shows a limited ability to execute CIP functions and promote  S. japonicus  mycelial development. Our findings also suggest that a modified N-lobe domain secondary structure within  S. japonicus  Pmk1 has a major influence on the CIP signaling features of this evolutionarily diverged fission

  {"abstract":"The post-cytokinetic separation of cells in cell-walled organisms involves enzymic processes that degrade a specific layer of the division septum and the region of the mother cell wall that edges the septum. In the fission yeast Schizosaccharomyces pombe, the 1,3-α-glucanase Agn1p, originally identified as a mutanase-like glycoside hydrolase family 71 (GH71) enzyme, dissolves the mother cell wall around the septum edge. Our search in the genomes of completely sequenced fungi identified GH71 hydrolases in Basidiomycota, Taphrinomycotina and Pezizomycotina, but not in Saccharomycotina. The most likely Agn1p orthologues in Pezizomycotina species are not mutanases having mutanase-binding domains, but experimentally non-characterized hypothetical proteins that have no carbohydrate-binding domains. The analysis of the GH71 domains corroborated the phylogenetic relationships of the Schizosaccharomyces species determined by previous studies, but suggested a closer relationship to the Basidiomycota proteins than to the Ascomycota proteins. In the Schizosaccharomyces genus, the Agn1p proteins are structurally conserved: their GH71 domains are flanked by N-terminal secretion signals and C-terminal sequences containing the conserved block YNFNA(Y)/HTG. The inactivation of the agn1(Sj) gene in Schizosaccharomyces japonicus, the only true dimorphic member of the genus, caused a severe cell-separation defect in its yeast phase, but had no effect on the hyphal growth and yeast-to-mycelium transition. It did not affect the mycelium-to-yeast transition either, only delaying the separation of the yeast cells arising from the fragmenting hyphae. The heterologous expression of agn1(Sj) partially rescued the separation defect of the agn1Δ cells of Schizosaccharomyces pombe. The results presented indicate that the fission yeast Agn1p 1,3-α-glucanases of Schizosaccharomyces japonicus and Schizosaccharomyces pombe share conserved functions in the yeast phase.

  {"abstract":"The phylogenesis of fungi is controversial due to their simple morphology and poor fossilization. Traditional classification supported by morphological studies and physiological traits placed the fission yeasts in one group with ascomycetous yeasts. The rRNA sequence comparisons, however, revealed an enormous evolutionary gap between Saccharomyces and Schizosaccharomyces. As shown in this review, the protein sequences also show a large gap which is almost as large as that separating Schizosaccharomyces from higher animals. Since the two yeasts share features (both cytological and molecular) in common which are also characteristic of ascomycetous fungi, their separation must have taken place later than the sequence differences may suggest. Possible reasons for the paradox are discussed. The sequence data also suggest a slower evolutionary rate in the Schizosaccharomyces lineage than in the Saccharomyces branch. In the fission yeast lineage two ramifications can be supposed.

  {"abstract":"Tropomyosins are structurally conserved α-helical coiled-coil proteins that bind along the length of filamentous actin (F-actin) in fungi and animals. Tropomyosins play essential roles in the stability of actin filaments and in regulating myosin II contractility. Despite the crucial role of tropomyosin in actin cytoskeletal regulation, in vivo investigations of tropomyosin are limited, mainly due to the suboptimal live-cell imaging tools currently available. Here, we report on an mNeonGreen (mNG)-tagged tropomyosin, with native promoter and linker length configuration, that clearly reports tropomyosin dynamics in Schizosaccharomyces pombe (Cdc8), Schizosaccharomyces japonicus (Cdc8) and Saccharomyces cerevisiae (Tpm1 and Tpm2). We also describe a fluorescent probe to visualize mammalian tropomyosin (TPM2 isoform). Finally, we generated a camelid nanobody against S. pombe Cdc8, which mimics the localization of mNG-Cdc8 in vivo. Using these tools, we report the presence of tropomyosin in previously unappreciated patch-like structures in fission and budding yeasts, show flow of tropomyosin (F-actin) cables to the cytokinetic actomyosin ring and identify rearrangements of the actin cytoskeleton during mating. These powerful tools and strategies will aid better analyses of tropomyosin and F-actin cables in vivo.","alleles_by_uniquename":{},"annotation_curators":[{"annotation_count":3,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana Oliferenko","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-11-25","authors":"Hatano T, Lim TC, Billault-Chaumartin I, Dhar A, Gu Y, Massam-Wu T, Scott W, Adishesha S, Chapa-Y-Lazo B, Springall L, Sivashanmugam L, Mishima M, Martin SG, Oliferenko S, Palani S, Balasubramanian MK","authors_abbrev":"Hatano T et al.","canto_added_date":"2022-11-25 12:03:53","canto_annotation_status":"APPROVED","canto_approved_date":"2022-11-25 12:11:22","canto_curator_name":"Snezhana Oliferenko","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2022-11-25 12:11:22","canto_session_key":"d572e8fc7f8a7a38","canto_session_submitted_date":"2022-11-25 12:11:07","canto_triage_status":"Curatable","citation":"J Cell Sci 2022 Sep 15;135(18)","cv_annotations":{"cellular_component":[{"annotations":[114360],"is_not":false,"summary":null,"term":"GO:0070648"},{"annotations":[114362],"is_not":false,"summary":null,"term":"GO:1990819"},{"annotations":[114361],"is_not":false,"summary":null,"term":"GO:0110085"}]},"doi":"10.1242/jcs.260288","gene_count":1,"genes_by_uniquename":{"SJAG_04887":null},"genotypes_by_uniquename":{},"ltp_gene_count":1,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2022","pubmed_entrez_date":"2022-09-23","pubmed_publication_date":"15 Sep 2022","terms_by_termid":{"GO:0070648":null,"GO:0110085":null,"GO:1990819":null},"title":"mNG-tagged fusion proteins and nanobodies to visualize tropomyosins in yeast and mammalian cells.","uniquename":"PMID:36148799"}

Understanding what determines the cellular amount of neutral lipids and their packaging into lipid droplets is of fundamental and applied interest. Using two species of fission yeast, we show that cycling cells deficient in the function of the ER-resident CDP-DG synthase Cds1 exhibit markedly increased triacylglycerol content and assemble large lipid droplets closely associated with the ER membranes. We demonstrate that these unusual structures recruit the triacylglycerol synthesis machinery and grow by expansion rather than by fusion. Our results suggest that interfering with the CDP-DG route of phosphatidic acid utilization rewires cellular metabolism to adopt a triacylglycerol-rich lifestyle reliant on the Kennedy pathway.

  {"abstract":"The cells of Schizosaccharomyces japonicus var. versatilis responded to the presence of cytochalasin D (CD), an inhibitor of actin polymerization, by the disappearance of contractile actin rings (ARs) that had already formed and by inhibition of new ring formation. Actin cables disappeared. Actin patches remained preserved and became co-localized with regions of actual cell wall formation (at cell poles and at the site of septum development). Removal of the AR arrested formation of the primary septum and led to the production of aberrant septum protrusions in that region. Nuclear division was accomplished in the presence of CD but new ARs were not produced. The wall (septum) material was deposited in the form of a wide band at the inner surface of the lateral cell wall in the cell centre. This layer showed a thin fibrillar structure. The removal of CD resulted in rapid formation of new ARs in the equatorial region of the cells. This implies that the signal for AR localization was not abolished either by CD effects or by removal of an AR already formed. Some of the newly developed ARs showed atypical localization and orientation. In addition, redundant, subcortically situated actin bundles were produced. The removal of CD was quickly followed by the development of primary septa co-localized with ARs. Wall protrusions occurred co-localized with the redundant actin bundles. If these were completed in a circle, redundant septa developed. The AR is a mechanism which, in time and space, triggers cytokinesis by building a septum sequentially dependent on the AR.

  {"abstract":"The fission yeasts (Schizosaccharomyces) representing a highly divergent phylogenetic branch of Fungi evolved from filamentous ancestors by gradual transition from mycelial growth to yeast morphology. For the transition, a mechanism had been developed that separates the sister cells after the completion of cytokinesis. Numerous components of the separation mechanism have been characterised in Schizosaccharomycespombe, including the zinc-finger transcription factor Ace2p and the fork-head transcription factor Sep1p. Here we show that both regulators have regions conserved within the genus. The most conserved parts contain the DNA-binding domains whose amino-acid sequences perfectly reflect the phylogenetic positions of the species. The less conserved parts of the proteins contain sequence blocks specific for the whole genus or only for the species propagating predominantly or exclusively as yeasts. Inactivation of either gene in the dimorphic species Schizosaccharomycesjaponicus abolished cell separation in the yeast phase conferring hypha-like morphology but did not change the growth pattern to unipolar and did not cause extensive polar vacuolation characteristic of the true mycelium. Neither mutation affected the mycelial phase, but both mutations hampered the hyphal fragmentation at the mycelium-to-yeast transition. Ace2p(Sj) acts downstream of Sep1p(Sj) and regulates the orthologues of the Ace2p-dependent S.pombe genes agn1(+) (1,3-alpha-glucanase) and eng1(+) (1,3-beta-glucanase) but does not regulate the orthologue of cfh4(+) (chitin synthase regulatory factor). These results and the complementation of the cell separation defects of the ace2(-) and sep1(-) mutations of S.pombe by heterologously expressed ace2(Sj) and sep1(Sj) indicate that the cell separation mechanism is conserved in the Schizosaccharomyces genus.","alleles_by_uniquename":{"SJAG_02252:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_02252","name":"ace2delta","uniquename":"SJAG_02252:allele-1"},"SJAG_03143:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03143","name":"sep1delta","uniquename":"SJAG_03143:allele-1"}},"annotation_curators":[{"annotation_count":7,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana Oliferenko","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-12-09","authors":"Balazs A, Batta G, Miklos I, Acs-Szabo L, Vazquez de Aldana CR, Sipiczki M","authors_abbrev":"Balazs A et al.","canto_added_date":"2022-12-09 17:19:01","canto_annotation_status":"APPROVED","canto_approved_date":"2022-12-09 17:39:12","canto_curator_name":"Snezhana Oliferenko","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2022-12-09 17:39:12","canto_session_key":"f106e12e6366fbad","canto_session_submitted_date":"2022-12-09 17:38:34","canto_triage_status":"Curatable","citation":"Fungal Genet Biol 2012 Mar;49(3):235-49","cv_annotations":{"single_locus_phenotype":[{"annotations":[114459,114460],"is_not":false,"summary":null,"term":"FYPO:0006557"}]},"doi":"10.1016/j.fgb.2012.01.003","gene_count":2,"genes_by_uniquename":{"SJAG_02252":null,"SJAG_03143":null},"genotypes_by_uniquename":{"ace2delta":{"display_name":"ace2delta","display_uniquename":"ace2delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_02252:allele-1","expression":"Null"}]}]},"sep1delta":{"display_name":"sep1delta","display_uniquename":"sep1delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_03143:allele-1","expression":"Null"}]}]}},"ltp_gene_count":2,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2012","pubmed_entrez_date":"2012-02-04","pubmed_publication_date":"Mar 2012","terms_by_termid":{"FYECO:0000137":null,"FYPO:0006557":null,"FYPO_EXT:0000001":null,"FYPO_EXT:0000002":null},"title":"Conserved regulators of the cell separation process in Schizosaccharomyces.","uniquename":"PMID:22300943"}

So far little is known about the natural and artificial habitats of species in this genus. Finding out where S. pombe and other fission yeast species occur and how they live in their habitats can promote better understanding of their biology. Here we investigate in which substrates S. pombe, S. octosporus, S. osmophilus and S. japonicus are present. To this end about 2100 samples consisting of soil, tree sap fluxes, fresh fruit, dried fruit, honey, cacao beans, molasses and other substrates were analyzed. Effective isolation methods that allow efficient isolation of the above mentioned species were developed. Based on the frequency of isolating different fission yeast species in various substrates and on extensive literature survey, conclusions are drawn on their ecology. The results suggest that the primary habitat of S. pombe and S. octosporus is honeybee honey. Both species were also frequently detected on certain dried fruit like raisins, mango or pineapple to which they could be brought by the honey bees during ripening or during drying. While S. pombe was regularly isolated from grape mash and from fermented raw cacao beans S. octosporus was never isolated from fresh fruit. The main habitat of S. osmophilus seems to be solitary bee beebread. It was rarely isolated from raisins. S. japonicus was mainly found in forest substrates although it occurs on fruit and in fruit fermentations, too.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Brysch-Herzberg M, Jia GS, Seidel M, Assali I, Du LL","authors_abbrev":"Brysch-Herzberg M et al.","canto_added_date":"2023-05-04 00:40:04","canto_curator_role":"JaponicusDB","canto_triage_status":"Phylogeny and evolutionary studies","citation":"Antonie Van Leeuwenhoek 2022 May;115(5):661-695","cv_annotations":{},"doi":"10.1007/s10482-022-01720-0","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2022","pubmed_entrez_date":"2022-04-01","pubmed_publication_date":"May 2022","terms_by_termid":{},"title":"Insights into the ecology of Schizosaccharomyces species in natural and artificial habitats.","uniquename":"PMID:35359202"}

  {"abstract":"After mitosis, nuclear reorganization occurs together with decondensation of mitotic chromosomes and reformation of the nuclear envelope, thereby restoring the Ran-GTP gradient between the nucleus and cytoplasm. The Ran-GTP gradient is dependent on Pim1/RCC1. Interestingly, a defect in Pim1/RCC1 in  Schizosaccharomyces pombe  causes postmitotic condensation of chromatin, namely hypercondensation, suggesting a relationship between the Ran-GTP gradient and chromosome decondensation. However, how Ran-GTP interacts with chromosome decondensation is unresolved. To examine this interaction, we used  Schizosaccharomyces japonicus , which is known to undergo partial breakdown of the nuclear membrane during mitosis. We found that Pim1/RCC1 was localized on nuclear pores, but this localization failed in a temperature-sensitive mutant of Pim1/RCC1. The mutant cells exhibited hypercondensed chromatin after mitosis due to prolonged association of condensin on the chromosomes. Conceivably, a condensin-dephosphorylation defect might cause hypercondensed chromatin, since chromosomal localization of condensin is dependent on phosphorylation by cyclin-dependent kinase (CDK). Indeed, CDK-phospho-mimic mutation of condensin alone caused untimely condensin localization, resulting in hypercondensed chromatin. Together, these results suggest that dephosphorylation of CDK sites of condensin might require the Ran-GTP gradient produced by nuclear pore-localized Pim1/RCC1.","alleles_by_uniquename":{"SJAG_00871:allele-1":{"allele_type":"amino_acid_mutation","description":"cut3-T19E","gene_uniquename":"SJAG_00871","name":"cut3-T19E","uniquename":"SJAG_00871:allele-1"},"SJAG_04284:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04284","name":"nup61delta","uniquename":"SJAG_04284:allele-1"},"SJAG_04464:allele-1":{"allele_type":"amino_acid_mutation","description":"R152C","gene_uniquename":"SJAG_04464","name":"pim1-R152C","synonyms":[{"name":"Inferred CDK-phospho-mimic mutation","reference":"PMID:28954740","type":"exact"}],"uniquename":"SJAG_04464:allele-1"}},"annotation_curators":[{"annotation_count":12,"community_curator":true,"file_name":null,"file_type":null,"name":"Sho Okamoto","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-11-23","authors":"Aoki K, Niki H","authors_abbrev":"Aoki K et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2022-11-23 15:00:26","canto_curator_name":"Sho Okamoto","canto_curator_role":"community","canto_first_approved_date":"2022-11-23 15:00:26","canto_session_key":"7c26b8235c98c3eb","canto_session_submitted_date":"2022-11-23 15:00:18","canto_triage_status":"Curatable","citation":"Biol Open 2017 Nov 15;6(11):1614-1628","cv_annotations":{"biological_process":[{"annotations":[114334],"is_not":false,"summary":null,"term":"GO:0101024"},{"annotations":[114339],"is_not":false,"summary":null,"term":"GO:0006998"}],"cellular_component":[{"annotations":[114338],"is_not":false,"summary":null,"term":"GO:0120321"}],"multi_locus_phenotype":[{"annotations":[114341],"is_not":false,"summary":null,"term":"FYPO:0000619"},{"annotations":[114340],"is_not":false,"summary":null,"term":"FYPO:0001489"}],"single_locus_phenotype":[{"annotations":[114342],"is_not":false,"summary":null,"term":"FYPO:0000619"},{"annotations":[114336],"is_not":false,"summary":null,"term":"FYPO:0003738"},{"annotations":[114343],"is_not":false,"summary":null,"term":"FYPO:0000815"},{"annotations":[114335],"is_not":false,"summary":null,"term":"FYPO:0000082"},{"annotations":[114337],"is_not":false,"summary":null,"term":"FYPO:0003976"},{"annotations":[114333],"is_not":false,"summary":null,"term":"FYPO:0001387"}]},"doi":"10.1242/bio.027193","gene_count":4,"genes_by_uniquename":{"SJAG_00471":null,"SJAG_00871":null,"SJAG_04284":null,"SJAG_04464":null},"genotypes_by_uniquename":{"cut3-T19E-cut3-T19E-amino_acid_mutation-expression-not_assayed_or_wild_type__pim1-R152C-R152C-amino_acid_mutation-expression-not_assayed_or_wild_type":{"display_name":"cut3-T19E(aa) pim1-R152C(aa)","display_uniquename":"cut3-T19E-cut3-T19E-amino_acid_mutation-expression-not_assayed_or_wild_type__pim1-R152C-R152C-amino_acid_mutation-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_00871:allele-1","expression":"Not assayed or wild type"}]},{"expressed_alleles":[{"allele_uniquename":"SJAG_04464:allele-1","expression":"Not assayed or wild type"}]}]},"nup61delta":{"display_name":"nup61delta","display_uniquename":"nup61delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_04284:allele-1","expression":"Null"}]}]},"pim1-R152C-R152C-amino_acid_mutation-expression-not_assayed_or_wild_type":{"display_name":"pim1-R152C(aa)","display_uniquename":"pim1-R152C-R152C-amino_acid_mutation-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_04464:allele-1","expression":"Not assayed or wild type"}]}]}},"ltp_gene_count":4,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[{"evidence":"Affinity Capture-Western","gene_uniquename":"SJAG_04464","interactor_uniquename":"SJAG_00471","reference_uniquename":"PMID:28954740","throughput":"low"}],"publication_year":"2017","pubmed_entrez_date":"2017-09-29","pubmed_publication_date":"15 Nov 2017","references_by_uniquename":{"PMID:28954740":null},"terms_by_termid":{"FYECO:0000004":null,"FYECO:0000005":null,"FYECO:0000137":null,"FYPO:0000082":null,"FYPO:0000619":null,"FYPO:0000815":null,"FYPO:0001387":null,"FYPO:0001489":null,"FYPO:0003738":null,"FYPO:0003976":null,"FYPO_EXT:0000001":null,"GO:0006998":null,"GO:0101024":null,"GO:0120321":null},"title":"Release of condensin from mitotic chromosomes requires the Ran-GTP gradient in the reorganized nucleus.","uniquename":"PMID:28954740"}

Although a great deal of molecular information is available from Schizosaccharomyces pombe, a model eukaryote, very little is available from other members of this group. In order to better characterize mitochondrial genome evolution in this fungal lineage, the mitochondrial DNA (mtDNA) of two additional fission yeasts, Schizosaccharomyces octosporus and Schizosaccharomyces japonicus var. japonicus, was sequenced.

The size variation of these mtDNAs is due largely to non-coding regions. The gene content in the latter two mtDNAs is almost identical to that of the completely sequenced S.pombe mtDNA, which encodes 25 tRNA species, the large and small mitochondrial ribosomal RNAs (rnl and rns), the RNA component of mitochondrial RNaseP (rnpB), mitochondrial small subunit ribosomal protein 3 (rps3), cytochrome oxidase subunits 1, 2 and 3 (cox1, cox2 and cox3) and ATP-synthase subunits 6, 8 and 9 (atp6, atp8 and atp9).

The mtDNA of S.octosporus contains five double hairpin elements, the first report of these elements in an ascomycete. This study provides further evidence in favor of the mobility of these elements, and supports their role in mitochondrial genome rearrangement.

The mutations complemented the phenotypes in a mutually dependent manner. Diploid zygotes, in which the two mutations were introduced simultaneously into the same cells, were isolated by selecting for adenine independence. Such diploid cells are apparently larger in size than haploid cells, yet have a similar nuclear/cytoplasmic ratio, and thus the nuclear size control that has been reported in Sz. pombe is also present in Sz. japonicus.","alleles_by_uniquename":{"SJAG_01081:allele-1":{"allele_type":"nonsense_mutation","description":"S427>stop","gene_uniquename":"SJAG_01081","name":"ade6-domE","uniquename":"SJAG_01081:allele-1"},"SJAG_01081:allele-2":{"allele_type":"amino_acid_mutation","description":"Q262A","gene_uniquename":"SJAG_01081","name":"ade6-domK","uniquename":"SJAG_01081:allele-2"},"SJAG_01081:allele-3":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01081","name":"ade6delta","uniquename":"SJAG_01081:allele-3"}},"annotation_curators":[{"annotation_count":3,"community_curator":true,"file_name":null,"file_type":null,"name":"Sho Okamoto","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2022-11-23","authors":"Furuya K, Niki H","authors_abbrev":"Furuya K et al.","canto_added_date":"2021-05-10 08:46:37","canto_annotation_status":"APPROVED","canto_approved_date":"2022-11-23 13:21:47","canto_curator_name":"Sho Okamoto","canto_curator_role":"community","canto_first_approved_date":"2022-11-23 13:21:47","canto_session_key":"7c1c894d4ee8d8d3","canto_session_submitted_date":"2022-11-23 13:21:40","canto_triage_status":"Curatable","citation":"Yeast 2011 Oct;28(10):747-54","cv_annotations":{"single_locus_phenotype":[{"annotations":[114316,114317,114318],"is_not":false,"summary":null,"term":"FYPO:0000747"}]},"doi":"10.1002/yea.1898","gene_count":1,"genes_by_uniquename":{"SJAG_01081":null},"genotypes_by_uniquename":{"ade6-domE-S427>stop-nonsense_mutation-expression-not_assayed_or_wild_type":{"display_name":"ade6-domE(S427>stop)","display_uniquename":"ade6-domE-S427>stop-nonsense_mutation-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01081:allele-1","expression":"Not assayed or wild type"}]}]},"ade6-domK-Q262A-amino_acid_mutation-expression-not_assayed_or_wild_type":{"display_name":"ade6-domK(Q262A aa)","display_uniquename":"ade6-domK-Q262A-amino_acid_mutation-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01081:allele-2","expression":"Not assayed or wild type"}]}]},"ade6delta":{"display_name":"ade6delta","display_uniquename":"ade6delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01081:allele-3","expression":"Null"}]}]}},"ltp_gene_count":1,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2011","pubmed_entrez_date":"2011-09-10","pubmed_publication_date":"Oct 2011","terms_by_termid":{"FYPO:0000747":null},"title":"Construction of diploid zygotes by interallelic complementation of ade6 in Schizosaccharomyces japonicus.","uniquename":"PMID:21905090"}

  {"abstract":"Cells of a specific cell type may divide within a certain size range. Yet, functionally optimal cellular organization is typically maintained across different cell sizes, a phenomenon known as scaling. The mechanisms underlying scaling and its physiological significance remain elusive. Here we approach this problem by interfering with scaling in the rod-shaped fission yeast Schizosaccharomyces japonicus that relies on cellular geometry cues to position the division site. We show that S. japonicus uses the Cdc42 polarity module to adjust its geometry to changes in the cell size. When scaling is prevented resulting in abnormal cellular length-to-width aspect ratio, cells exhibit severe division site placement defects. We further show that despite the generally accepted view, a similar scaling phenomenon can occur in the sister species, Schizosaccharomyces pombe. Our results demonstrate that scaling is required for normal cell function and delineate possible rules for cellular geometry maintenance in populations of proliferating cells.","alleles_by_uniquename":{"SJAG_00028:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00028","name":"rga6delta","uniquename":"SJAG_00028:allele-1"},"SJAG_00514:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_00514","name":"scd1delta","uniquename":"SJAG_00514:allele-1"},"SJAG_03048:allele-1":{"allele_type":"amino_acid_mutation","description":"G146D","gene_uniquename":"SJAG_03048","name":"cdc2-1w","uniquename":"SJAG_03048:allele-1"},"SJAG_03581:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03581","name":"gef1delta","uniquename":"SJAG_03581:allele-1"},"SJAG_04280:allele-1":{"allele_type":"amino_acid_mutation","description":"T582G","gene_uniquename":"SJAG_04280","name":"wee1-as8","uniquename":"SJAG_04280:allele-1"},"SJAG_04280:allele-2":{"allele_type":"amino_acid_mutation","description":"G788E","gene_uniquename":"SJAG_04280","name":"wee1-G788E","uniquename":"SJAG_04280:allele-2"},"SJAG_04522:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_04522","name":"rga4delta","uniquename":"SJAG_04522:allele-1"}},"annotation_curators":[{"annotation_count":3,"community_curator":false,"file_name":null,"file_type":null,"name":"Val

  {"abstract":"Gene targeting is a commonly used method to reveal the function of genes. Although it is an attractive tool for molecular studies, it can frequently be a challenge because its efficiency can be low and it requires the screening of a large number of transformants. Generally, these problems originate from the elevated level of ectopic integration caused by non-homologous DNA end joining (NHEJ). To eliminate this problem, NHEJ-related genes are frequently deleted or disrupted. Although these manipulations can improve gene targeting, the phenotype of the mutant strains raised the question of whether mutations have side effects. The aim of this study was to disrupt the  lig4  gene in the dimorphic fission yeast,  S. japonicus , and investigate the phenotypic changes of the mutant strain. The mutant cells have shown various phenotypic changes, such as increased sporulation on complete medium, decreased hyphal growth, faster chronological aging, and higher sensitivity to heat shock, UV light, and caffeine. In addition, higher flocculation capacity has been observed, especially at lower sugar concentrations. These changes were supported by transcriptional profiling. Many genes belonging to metabolic and transport processes, cell division, or signaling had altered mRNA levels compared to the control strain. Although the disruption improved the gene targeting, we assume that the  lig4  inactivation can cause unexpected physiological side effects, and we have to be very careful with the manipulations of the NHEJ-related genes. To reveal the exact mechanisms behind these changes, further investigations are required.","alleles_by_uniquename":{"SJAG_02527:allele-1":{"allele_type":"disruption","description":"RNA sequencing revealed that only the 5' end of the disrupted allele showed low RNA expression and coverage","gene_uniquename":"SJAG_02527","name":"lig4::KanMX6","uniquename":"SJAG_02527:allele-1"}},"annotation_curators":[{"annotation_count":7,"community_curator":true,"file_name":null,"file_type":null,"name":"Ida Miklos","orcid":null}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2023-08-08","authors":"Acs-Szabo L, Papp LA, Takacs S, Miklos I","authors_abbrev":"Acs-Szabo L et al.","canto_added_date":"2023-05-27 00:40:04","canto_annotation_status":"APPROVED","canto_approved_date":"2023-08-08 20:07:33","canto_curator_name":"Ida Miklos","canto_curator_role":"community","canto_first_approved_date":"2023-08-08 20:07:33","canto_session_key":"c74bdd0a67b132f8","canto_session_submitted_date":"2023-08-08 20:07:15","canto_triage_status":"Curatable","citation":"J Fungi (Basel) 2023 May 10;9(5)","cv_annotations":{"single_locus_phenotype":[{"annotations":[114112],"is_not":false,"summary":null,"term":"FYPO:0007776"},{"annotations":[114114],"is_not":false,"summary":null,"term":"FYPO:0009111"},{"annotations":[114111],"is_not":false,"summary":null,"term":"FYPO:0000588"},{"annotations":[114117],"is_not":false,"summary":null,"term":"FYPO:0005705"},{"annotations":[114115],"is_not":false,"summary":null,"term":"FYPO:0005231"},{"annotations":[114113],"is_not":false,"summary":null,"term":"FYPO:0000097"},{"annotations":[114116],"is_not":false,"summary":null,"term":"FYPO:0001408"}]},"doi":"10.3390/jof9050550","gene_count":1,"genes_by_uniquename":{"SJAG_02527":null},"genotypes_by_uniquename":{"lig4::KanMX6-RNA_sequencing_revealed_that_only_the_5'_end_of_the_disrupted_allele_showed_low_RNA_expression_and_coverage-disruption-expression-knockdown":{"display_name":"lig4::KanMX6(RNA sequencing revealed that only the 5' end of the disrupted allele showed low RNA expression and coverage)[Knockdown]","display_uniquename":"lig4::KanMX6-RNA_sequencing_revealed_that_only_the_5'_end_of_the_disrupted_allele_showed_low_RNA_expression_and_coverage-disruption-expression-knockdown","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_02527:allele-1","expression":"Knockdown"}]}]}},"ltp_gene_count":1,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2023","pubmed_entrez_date":"2023-05-26","pubmed_publication_date":"10 May 2023","terms_by_termid":{"FYECO:0000005":null,"FYECO:0000081":null,"FYECO:0000117":null,"FYECO:0000126":null,"FYECO:0000137":null,"FYECO:0000315":null,"FYPO:0000097":null,"FYPO:0000588":null,"FYPO:0001408":null,"FYPO:0005231":null,"FYPO:0005705":null,"FYPO:0007776":null,"FYPO:0009111":null},"title":"Disruption of the  Schizosaccharomyces japonicus lig4  Disturbs Several Cellular Processes and Leads to a Pleiotropic Phenotype.","uniquename":"PMID:37233261"}

  {"abstract":"During cellular proliferation, the mother nucleus divides into two daughters, each carrying a full complement of chromosomes and capable of driving the next cell cycle. Mitotic chromosome segregation must be coordinated with remodeling of other nuclear components, including the nuclear envelope (NE) and the non-membrane-bound nucleolus. Here, we show that in the fission yeast Schizosaccharomyces japonicus, which breaks and reforms the NE during mitosis, the evolutionary conserved LEM-domain protein Man1 promotes equal partitioning of the nuclear membrane, nucleolar remodeling, and efficient inheritance of the nuclear pore complexes (NPCs) by the daughter nuclei. Analyses of man1 mutants and results obtained using an artificial chromatin-nuclear pore tether suggest that Man1 may exert its function by linking the NPCs to segregating chromatin. By integrating the partitioning of the nuclear membrane and nucleolar material with chromosome segregation, cells build two nearly identical copies of the original nucleus.","alleles_by_uniquename":{"SJAG_01834:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_01834","name":"pom152delta","uniquename":"SJAG_01834:allele-1"},"SJAG_03449:allele-1":{"allele_type":"deletion","description":"deletion","gene_uniquename":"SJAG_03449","name":"man1delta","uniquename":"SJAG_03449:allele-1"},"SJAG_03449:allele-2":{"allele_type":"partial_amino_acid_deletion","description":"man1DHEH","gene_uniquename":"SJAG_03449","name":"Man1DHEH","uniquename":"SJAG_03449:allele-2"},"SJAG_03449:allele-3":{"allele_type":"amino_acid_insertion_and_deletion","description":"man1-1-488","gene_uniquename":"SJAG_03449","name":"man1-1-488","uniquename":"SJAG_03449:allele-3"}},"annotation_curators":[{"annotation_count":17,"community_curator":false,"file_name":null,"file_type":null,"name":"Snezhana Oliferenko","orcid":"0000-0002-8138-6851"},{"annotation_count":2,"community_curator":false,"file_name":null,"file_type":null,"name":"Val Wood","orcid":"0000-0001-6330-7526"}],"annotation_details":{},"annotation_file_curators":[],"approved_date":"2021-07-27","authors":"Yam C, Gu Y, Oliferenko S","authors_abbrev":"Yam C et al.","canto_added_date":"2021-05-10 02:38:18","canto_annotation_status":"APPROVED","canto_approved_date":"2021-09-01 07:25:17","canto_curator_name":"Snezhana Oliferenko","canto_curator_role":"JaponicusDB","canto_first_approved_date":"2021-07-27 11:54:17","canto_session_key":"0f2dda384385121f","canto_session_submitted_date":"2021-07-27 11:54:10","canto_triage_status":"Curatable","citation":"Curr Biol 2013 Nov 18;23(22):2303-2310","cv_annotations":{"biological_process":[{"annotations":[114206],"is_not":false,"summary":null,"term":"GO:0101024"}],"cellular_component":[{"annotations":[114191],"is_not":false,"summary":null,"term":"GO:0000781"},{"annotations":[114190],"is_not":false,"summary":null,"term":"GO:0140573"},{"annotations":[114193],"is_not":false,"summary":null,"term":"GO:0005643"},{"annotations":[114192],"is_not":false,"summary":null,"term":"GO:0030875"}],"molecular_function":[{"annotations":[114207],"is_not":false,"summary":null,"term":"GO:0062239"}],"single_locus_phenotype":[{"annotations":[114194,114199,114201],"is_not":false,"summary":null,"term":"FYPO:0003779"},{"annotations":[114203,114204,114205],"is_not":false,"summary":null,"term":"FYPO:0000671"},{"annotations":[114196,114197,114198,114200],"is_not":false,"summary":null,"term":"FYPO:0004890"},{"annotations":[114195],"is_not":false,"summary":null,"term":"FYPO:0001234"},{"annotations":[114202],"is_not":false,"summary":null,"term":"FYPO:0004683"}]},"doi":"10.1016/j.cub.2013.09.057","gene_count":5,"genes_by_uniquename":{"SJAG_00302":null,"SJAG_01777":null,"SJAG_01834":null,"SJAG_03449":null,"SJAG_03603":null},"genotypes_by_uniquename":{"Man1DHEH-man1DHEH-partial_amino_acid_deletion-expression-not_assayed_or_wild_type":{"display_name":"Man1DHEH(man1DHEH)","display_uniquename":"Man1DHEH-man1DHEH-partial_amino_acid_deletion-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_03449:allele-2","expression":"Not assayed or wild type"}]}]},"man1-1-488-man1-1-488-amino_acid_insertion_and_deletion-expression-not_assayed_or_wild_type":{"display_name":"man1-1-488(aa)","display_uniquename":"man1-1-488-man1-1-488-amino_acid_insertion_and_deletion-expression-not_assayed_or_wild_type","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_03449:allele-3","expression":"Not assayed or wild type"}]}]},"man1delta":{"display_name":"man1delta","display_uniquename":"man1delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_03449:allele-1","expression":"Null"}]}]},"pom152delta":{"display_name":"pom152delta","display_uniquename":"pom152delta","loci":[{"expressed_alleles":[{"allele_uniquename":"SJAG_01834:allele-1","expression":"Null"}]}]}},"ltp_gene_count":5,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2013","pubmed_entrez_date":"2013-11-05","pubmed_publication_date":"18 Nov 2013","terms_by_termid":{"FYECO:0000005":null,"FYECO:0000162":null,"FYPO:0000671":null,"FYPO:0001234":null,"FYPO:0003779":null,"FYPO:0004683":null,"FYPO:0004890":null,"FYPO_EXT:0000001":null,"FYPO_EXT:0000002":null,"FYPO_EXT:0000003":null,"GO:0000781":null,"GO:0005643":null,"GO:0030875":null,"GO:0062239":null,"GO:0101024":null,"GO:0140573":null},"title":"Partitioning and remodeling of the Schizosaccharomyces japonicus mitotic nucleus require chromosome tethers.","uniquename":"PMID:24184107"}

  {"abstract":"Both budding yeast Saccharomyces cerevisiae and fission yeast Schizosaccahromyces pombe have been very popular organisms used for biological research with eukaryotes for many decades. Judging from the fission yeast Schizosaccharomyces japonicus DNA sequence determined 2 years ago, this species is evolutionarily very much unrelated to the commonly used yeasts for research. Indicating evolutionary divergence, the S. japonicus makes 8-spored asci and mitosis occurs with a partial breakdown of nuclear membrane whereas the other yeasts make 4-spored asci and cells divide without nuclear breakdown. The commonly used yeast species exhibit a generation time between 1.5 and 2.0 hr, and their genetic cross takes a period of more than 7 working d. As described here, a generation time of only 63 min and meiotic analysis completed in just 2.5 d, the S. japonicus fission yeast is predicted to become a choice organism for future research on the biology of eukaryotes.

  {"abstract":"Fission yeasts form a small but heterogeneous group of ascomycetes and it is still unclear whether they should be subdivided into three genera (Schizosaccharomyces, Octosporomyces, Hasegawaea) or remain a single genus (Schizosaccharomyces). In order to decide whether a new genus Hasegawaea should be established for the species Schizosaccharomyces japonicus and Schizosaccharomyces versatilis, we have characterized the entire rDNA cluster in Schizosaccharomyces japonicus var. versatilis and compared it with the homologous region from Schizosaccharomyces pombe and with complete rRNA gene sequences from other yeast genera. From a phage genomic library a recombinant lambda phage containing the entire rDNA repeat unit was isolated. In this paper we report the primary sequence of the 18s, 5.8s and 25s rRNA coding regions. The S. japonicus var. versatilis rRNA genes are 1823 (18s), 158 (5.8s) and 3422 (25s) nucleotides long. The two sequences of the larger rRNA genes exhibit 95.7% (18s) and 93% (25s) similarity with the homologous genes from S. pombe. The differences between the rRNA genes of S. japonicus and S. pombe, however, are much smaller than the intrageneric differences within the rDNA sequences of other yeast genera. Therefore, subdivision of fission yeasts into the genera Schizosaccharomyces and Hasegawaea does not to seem to be justified.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Naehring J, Kiefer S, Wolf K","authors_abbrev":"Naehring J et al.","canto_added_date":"2021-05-10 08:46:37","canto_curator_role":"JaponicusDB","canto_triage_status":"Sequence feature or region","citation":"Curr Genet 1995 Sep;28(4):353-9","cv_annotations":{},"gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"1995","pubmed_entrez_date":"1995-09-01","pubmed_publication_date":"Sep 1995","terms_by_termid":{},"title":"Nucleotide sequence of the Schizosaccharomyces japonicus var. versatilis ribosomal RNA gene cluster and its phylogenetic implications.","uniquename":"PMID:8590481"}

  {"abstract":"Making wine via spontaneous fermentation without sulfur dioxide and commercial yeast (spontaneous winemaking) is increasing in recent year, but there is scant research regarding microbial communities present in Japan during spontaneous winemaking using culture-independent molecular methods. We analyzed fungal communities and populations during laboratory-scale spontaneous winemaking using sterilized labware to avoid winery-resident microbes. In the spontaneous fermentation of four grape varieties (Pinot Noir, Riesling, Koshu, and Koshusanjaku) grown in the same Japanese vineyard, our analysis of yeast and other fungal species by next-generation sequencing based on the ITS1 region demonstrated that Saccharomyces cerevisiae was eventually dominant in seven of 12 fermentation batches (three replications for each grape variety), whereas non-Saccharomyces species (e.g., Schizosaccharomyces japonicus, Lachancea dasiensis, and Hanseniaspora valbyensis) became dominant in four batches at the end of fermentation. In another batch, lactic acid bacteria (LAB) became dominant and the fermentation remained incomplete. Diverse microbes were involved in the spontaneous fermentation (particularly in Koshusanjaku), indicating that residual sugar remained and lactic and acetic acid largely increased. Compared to the control wine made with SO 2  and commercial yeast, the concentration of lactic acid was 47-fold higher in the must dominated by L. dasiensis, and the concentrations of acetic acid and lactic acid were 10-fold and 20-fold higher in the must dominated by LAB, respectively. Even when indigenous S. cerevisiae became dominant, the finished wines obtained high sensory-analysis scores for complexity but low scores for varietal typicality, indicating the risk of fermentation with unselected wild yeast on the grapes grown in Japan.","alleles_by_uniquename":{},"annotation_curators":[],"annotation_details":{},"annotation_file_curators":[],"authors":"Shimizu H, Kamada A, Koyama K, Iwashita K, Goto-Yamamoto N","authors_abbrev":"Shimizu H et al.","canto_added_date":"2023-05-04 00:40:03","canto_curator_role":"JaponicusDB","canto_triage_status":"Cell composition or WT feature","citation":"J Biosci Bioeng 2023 Apr 21;","cv_annotations":{},"doi":"10.1016/j.jbiosc.2023.03.013","gene_count":0,"genes_by_uniquename":{},"genotypes_by_uniquename":{},"ltp_gene_count":0,"ortholog_annotations":[],"paralog_annotations":[],"physical_interactions":[],"publication_year":"2023","pubmed_entrez_date":"2023-04-23","pubmed_publication_date":"21 Apr 2023","terms_by_termid":{},"title":"Yeast diversity during the spontaneous fermentation of wine with only the microbiota on grapes cultivated in Japan.","uniquename":"PMID:37088673"}
