COG categories in the three R. palustris strains. Functional categorization of genes was performed by the COG database⁹². The y-axis indicates the percentage of genes assigned with the COG category relative to all genes. The x-axis represents the COG functional category. The groups in each COG category are as follows: (B) chromatin structure and dynamics; (C) energy production and conversion; (D) cell cycle control, cell division and chromosome partitioning; (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; (J) translation, ribosomal structure and biogenesis; (K) transcription; (L) replication, recombination and repair; (M) cell wall/membrane/envelope biogenesis; (N) cell motility; (O) posttranslational modification, protein turnover and chaperones; (P) inorganic ion transport and metabolism; (Q) secondary metabolite biosynthesis, transport and catabolism; (R) general function prediction only; (S) function unknown; (T) signal transduction mechanisms; (U) intracellular trafficking, secretion and vesicular transport; (V) defense mechanisms; (W) extracellular structures; (X) mobilome: prophages and transposons; and (NA) no COG assignment.
