Figure 3

Four-way-Venn-diagram of the distribution of unique and shared gene families among Phytophthora species. Homologous proteins in P. cactorum, P. infestans, P. sojae and P. ramorum were clustered into gene families using TribeMCL. Numbers in individual sections indicate number of gene families (not genes). Overlapping regions denote groups with at least two proteins of all species that are part of the intersection. The first number under the organism name gives the total number of clusters that the respective organism contributes to; the second number describes the total number of each organism’s gene models/sequences that go into clusters. The difference of the second number to an organism’s total input proteins gives the number of singletons (protein sequences that do not cluster at all in this analysis).
