Figure 3
A maximum-likelihood phylogenomic tree generated by a set of 2,073 core genes found across all 20 oomycete genomes (total concatenated multiple sequence alignment length of 2,455,151). Descriptions of all 2,073 core genes are shown in Supplementary Table S1. The tree categorizes all Pythium species, except Pythium vexans (currently reclassified as Phytopythium vexans; indicated by asterisk), into clades A and B. The reliability of the trees tested by bootstrap analysis to support each branch is indicated.
