Based on retention of paralogs resulting from ancient polyploidization in three rosids and three asterids. Retained genes identified in homeologous syntenic blocks detected by SynMap [17, 18]. “Increase in fractionation resistance” ranges from 1 (singleton in all three species) to 4 (three paralogs retained in all species). “Normalized proportions” measures how many of the gene paralogy groups with a given fractionation resistance are annotated by a specific Gene Ontology (GO) term. E.g., in the rosids, 80% of the paralogy groups with fractionation resistance 1 are annotated with the GO term “Cellular Process”. From [14], Figure 3
