Fig. 6.

Synonymous (A) and nonsynonymous (B) substitutions per site per year and their ω ratios (C) estimated for 158 core shared genes between Portiera lineages of six whitefly species. Different letters indicate significant statistical differences between lineages (nonparametric Kruskal–Wallis and Wilcoxon post hoc pairwise tests). Synonymous (D) and nonsynonymous (E) substitutions per site per year and ω ratios (F) estimated for ten full mitochondrial genes from six whiteflies species. N.S., no significant difference. Different letters indicate significant statistical differences between lineages (one-way ANOVA and Tukey’s post hoc test). Organism abbreviations are as table 2.
