Enrichment of COG categories in several OG sets. The ordinates axis shows the COG categories. The subordinate axis accounts for the difference between the representation of the category in the OG set and the representation of the category in the reference genome Xeu8. Each bar represents a category in a given OG set. Sets from lighter to darker are: Xeu8 genes discarding in-paralogs; X. axonopodis clade, including Xeu8, XamC, Xci3, Xfa0 and Xfa1; No-XalG, including all the genomes in the study but XalG; Xanthomonas, including all the genomes in the genus Xanthomonas. Error bars indicate one positive and one negative standard deviation calculated as described in the methods. Categories increasing in representation at wider taxonomical ranges are hued blue. Categories decreasing in representation at wider taxonomical ranges are hued red. Other categories are hued green.
