Qualitative Data

  • Each annotation must consist of these 4 bits of data:
    • Expression type RNA or protein level
    • Relation during(BP) or in_presence_of(ChEBI)
    • Level present, absent, unchanged, increased, decreased, constant
      • present during vegetative growth (if no unstressed control, the present during stress also ok)
      • unchanged/decreased/increased in stress
      • constant during cell cycle
    • Evidence ECO:xxxxxxx

  • The expression type may, if it is known, be further subdivided into:
    • RNA level -> transcription or RNA degradation
    • protein level -> translation or protein degradation
  • Unstressed conditions include during "vegetative growth of single-celled organism" (=whole cell extract) or "mitotic/meiotic cell cycle" (= they looked at different phases))
  • Unstressed conditions include growth on YE and MM unless there is a known difference between the two

  • will be converted to annotation_extension=during(GO:0072690)

A property value that captures whether the expression is determined at the level of a single cell or a population. Related but not identical to evidence (some kinds of evidence allow inferences about expression in an individual cell, whereas other evidence types only support population-level inferences). Property name is "qual_gene_ex_cell_distribution"; value can be "population wide" or "single cell".
