Gene counts for each COG category in the core genome for non-plant-associated (nPA) vs. plant-associated (PA) groups. Each pair of columns represents the COG category of the specific genes. Cellular process and signaling: D, cell cycle control, cell division, chromosome partitioning; M, cell wall/membrane/envelope biogenesis; N, cell motility; O, posttranslational modification, protein turnover, chaperones; T, signal transduction mechanisms; V, defense mechanisms. Metabolism: C, energy production and conversion; E, amino acid transport and metabolism; F, nucleotide transport and metabolism; G, carbohydrate transport and metabolism; H, coenzyme transport and metabolism; I, lipid transport and metabolism; P, inorganic ion transport and metabolism; Q, secondary metabolites biosynthesis, transport and catabolism. Information storage and processing: J, translation, ribosomal structure, and biogenesis; K, transcription; L, replication, recombination and repair. Poorly characterized: R, general function prediction only; S, function unknown.
