Figure 4
Gene ontology (GO) categories exhibiting enrichment (p<0.05, uncorrected) for orthologs with significantly elevated d N /d S along the clade C and D lineages, respectively. If multiple hierarchical categories were all enriched and included the exact same subset of orthologs, only the most specific of these categories is shown. Numbers indicate the number of orthologs with significantly elevated dN/dS in each category. The arrows connect categories that contain a subset of the orthologs found within other enriched categories. These connections do not necessarily represent GO hierarchical relationships.
