Enrichment of functional categories among positively selected genes.

Bar chart with the fold change comparing the proportion of genes under positive selection and without positive selection in the y-axis, and the several KOG functional categories in the x-axis. For each functional category, fold change values are presented for the basidioPAML and basidioPAML_Hv data sets, according to the legend in the top right corner of the figure. Bars with an asterisk (“*”) represent statistically significant results for p < 0.1.
