Gene family evolution. (A) Characterization of the paralogous genes among five entomopathogenic fungi. Abbreviations: OSI, O. sinensis; MAN, M. anisopliae; MAC, M. acridum; CMI, C. militaris; BBA, B. bassiana; SCE, S. cerevisiae. The x-axis shows the amino acid identity for each paralogous pair, while z-axis indicates the total number of paralogous genes within identity groups. Paralogous gene pairs are detected based on all-vs-all comparisons within the same species using Blastall program (version 2.2.26). (B) Gene expansion and contraction in the O. sinensis genome. The numbers of gene families showing expansion (red) or contraction (green) for each lineage after speciation are indicated on each branch of the phylogenetic tree with the position of O. sinensis highlighted (blue asterisk). (C) Venn diagram depicting unique and shared gene families among the five fungal genomes. Actual gene numbers are indicated (parentheses).
