Note.—PSGs were identified as those genes with posterior probability ≥ 0.95 for the hypothesis of the gene having a dN/dS ratio higher than expected from the interaction between the gene factor and the branch factor. The gall inducer S. itoensis consistently displays the highest number of PSGs (values in bold).
