Fig 1. Five-way-Venn-diagram of unique and shared gene families among oomycete species.

Homologous proteins in P. litchii, H. arabidopsidis, P. halstedii, P. infestans, and P. sojae were clustered into gene families using OrthoMCL. Numbers in each section refer to number of gene families (not genes). Overlapping regions denote groups with at least one protein of all species that are part of the intersection. The number under the organism name refer to the total number of clusters.
