Figure 9
Frequency distribution and taxonomic coverage of putatively orthologous protein sets of different sizes. Panel (a) shows the number of orthologous sets based on the number of proteins they contain. Only the retained sets of size ≥ 4, which can generate unrooted phylogenetic trees that are informative, are shown. Panels (b)-(e) show the number of taxonomic groups covered by sets at the taxonomic ranks of phylum, order, genus and species.
