Gene distributions of 17 species in Cytophagales. a Percentage relative abundances of gene clusters in Cytophagales. The values are centered and scaled in the row direction. Two main COG clusters (left) are observed: highly retained categories (U, J, L, D, O, M, I, Z) and low retained categories free-living bacteria (latter 13). b Percentages of 4 categories in Cytophagales. Compared with the free-living bacteria, the host-dependent endosymbionts have higher percentages of genes related tothe information storage and processing (green), with lower percentages of genes involved in metabolism (blue). J: Translation, ribosomal structure and biogenesis; K: Transcription; L: Replication, recombination and repair; B: Chromatin structure and dynamics; C: Energy production and conversion; G: Carbohydrate transport and metabolism; E: Amino acid transport and metabolism; F: Nucleotide transport and metabolism; H: Coenzyme transport and metabolism; I: Lipid transport and metabolism; P: Inorganic ion transport and metabolism; Q: Secondary metabolite biosynthesis, transport and catabolism; D: Cell cycle control, cell division, chromosome partitioning; V: Defense mechanisms; T: Signal transduction mechanisms; M: Cell wall/membrane biogenesis; N: Cell motility; Z: Cytoskeleton; U: Intracellular trafficking and vesicular transport; O: Post-translational modification, protein turnover andchaperones; R: General function prediction only; S: Function unknown.
