The distribution of phenotypic annotations. (a) Frequency of genes associated with a number of different RNAi phenotypes (0–6) per cell type. Phenotypes refer to those identified by seven major annotation categories. From 0 up to 6 phenotypes per gene were observed; '0' indicates those genes without detectable phenotypes in the one cell type (but were detected in the other). The set included all 160 genes identified by an RNAi phenotype in each of either S2R+ (gray) or Kc167 (black) cell types. (b) The percentage of genes associated with a certain combined phenotypic annotation in both cell types screened. The percentage is the number of genes identified with 0 to 6 phenotypic annotations in Kc167 cells (normalized to 100%) that were also associated with 0 to 6 phenotypic annotations in S2R+ cells (colored fractions of columns; see the key).
