Figure 2.

Scatter plots of sequence similarity between S. pombe proteins and their homologs from S. cerevisiae, plants, and animals. Horizontal axis: −log₁₀[E value (S. pombe with S. cerevisiae)]. Vertical axis: log₁₀[E-value (S. pombe with S. cerevisiae)] − log₁₀ [E-value (S. pombe with nonfungal eukaryote)]. The thick, horizontal line indicates the 10 orders of magnitude threshold used to delineate the set of anomalous hits that were analyzed further for likely cases of gene loss and divergence. (A) Metazoa vs. S. cerevisiae. (B) Plants vs. S. cerevisiae
