Divergence and dN/dS analysis. a Estimation of the divergence times of selected fungal plant pathogens. The ultrametric tree was inferred from 439 single-copy orthologs (predicted coding sequences). Divergence times were estimated using r8s and calibrated on the 452 million years divergence between Ascomycetes and Basidiomycetes. B: Blumeria; M: Melampsora; P: Puccinia; T: Tilletia; U: Ustilago; and Z: Zymoseptoria. Z. tritici traditionally called Mycosphaerella graminicola. b Comparison of 4486 pairs of Pst (93–210) and Psh (93TX-2) single-copy homologs. The X axis represents the ratio of nonsynonymous to synonymous substitutions (dN/dS) for all gene pairs, and the Y axis represents the number of gene pairs in each dN/dS range. The orange bars represent the 478 gene pairs of Pst (93–210) and Psh (93TX-2) single-copy homologs encoding secreted protein (SP) genes, and the green bars represent the 4008 non-SP-coding gene pairs. For better visibility, the numbers for non-SP genes were divided by 10
