Predicted Cluster of Orthologous Groups (COG) functional classes. COG functional classes were determined for the 995 pan-gene clusters that met the criteria (psiblast, coverage ≥ 70%, percent identity ≥ 70%, and e-value ≤ 10–5). A The total frequencies of pan-gene clusters classified into each COG functional class (single-letter code) were plotted and color-coded. B The percentages of accessory and core pan-gene clusters classified into each COG functional class were plotted. Dark and light shading represents core and accessory pan-gene clusters, respectively. C The percentages of pan-gene clusters (from each COG class) present in each pathotype. Dark, medium, and light shading represents pan-gene clusters present in the pathogenic, possibly opportunistic, and commensal pathotypes, respectively.
