  1. Levels of divergence in coding region are calculated for fixed differences (excluding polymorphism) for ks (synonymous substitutions per site) and ka (non-synonymous substitutions per site) with a Jukes-Cantor correction. Raw numbers of changes and sites can be found in Additional file 2: Table S1. Note that the GOT1Sd sequences spanned only one-half of the coding region of GOT1Sr (504 bp vs 1122 bp) and that the reading frame was corrected when calculating numbers of synonymous and nonsynonymous substitutions.
