(A) Cumulative codon rate ratios; (B) distribution of ω values in comparison with CAI. A) The figure shows cumulative (percentage) codon rate ratios for total Shewanellaceae and Vibrionaceae orthologs. S. benthica vs. S. frigidimarina and P. profundum vs. V. vulnificus cumulative ω ratios are represented respectively by black and gray lines. B) Distribution of the ω (dN/dS) values computed between the orthologous genes of S. benthica and S. frigidimarina in comparison with the Codon Adaptation Index calculated for S. benthica. The Spearman correlation coefficient (ρ) calculated between ω and CAI values is -0.32. PS genes identified in KT99 are highlighted in black. The graph reported is representative of those calculated in all other organisms.
