Identity, similarity, and conservation level of the ora genes. (A) dN/dS ratios of the six ora genes. For each gene, the dN/dS ratio was determined for all possible pairwise comparisons between orthologs and the mean value was plotted. (B) Amino acid percent identity is calculated for each gene comparisons between orthologs or species (paralog comparisons) by averaging the values of all possible pairwise comparisons inside the described group. (C) Amino acid % similarity is calculated for each gene or species by averaging the values of all possible pairwise comparisons inside the described group. (A–C) The bars correspond to the associated standard deviation as a measure of the variance within each group. (B,C) Differences between values for ortholog and paralog comparisons are highly significant.
