COG functional categorization of sequenced Paenibacillus polymyxa genomes. COG functional categorization was performed using available tools on the JGI IMG database. A) Proportion of total CDS versus COG categories for the four completely sequenced P. polymyxa strains. Functional categories A, B, W, and Y correspond to eukaryotic functions and contained no homologs in any sequenced Paenibacillus polymyxa genome and are thus omitted. B) List of COG categories and their respective functions.
