Genes and functional enrichments in the core and accessory genomes of 12 species. a Number of genes in the core and accessory genomes of each species. b Comparison of core genome size, accessory genome size, and pangenome openness. c Functional enrichments by COG functional category in the 12 core and accessory genomes. The distribution of log2 odds ratios (LORs), as well as the number of species with significant enrichment by COG are shown (Fisher’s exact test, FWER < 0.05 under Bonferroni correction or p < 7*10^− 5, 720 tests). Only COGs showing positive enrichment in over half the species and with mean LOR > 1 are shown. COG “S: Function unknown” is not shown
