COG analysis of “Candidatus Pinguicoccus supinus” and other bacteria with highly reduced genome. (A) Principal Component Analysis of numerosity in COG classes; explained variance by Component one 32%; explained variance by Component two 24%; (B) Distribution of COGs in each analysed genome; (C) Distribution of COGs, showing: i. percentage of COGs shared by all the analysed genomes, COGs unique for each genome, and COGs shared by at least two genomes; ii. Number of organisms sharing COGs. Each set groups together the COGs shared by a given number of organisms (i.e. 1, 2, 3…7), regardless of their identity; iii. Percentage of unique COGs in analyzed genomes.
