  1. 1Ratio of nonsynonymous substitutions per nonsynonymous sites to synonymous substitutions per synonymous sites based on M0 model of PAML.
  2. 2P-value of the McDonald-Kreitman test (group A vs. B) [33].
  3. 3P-values of likelihood ratio tests for both M1a vs. M2a, and M7 vs. M8 in PAML [34]. Significant value indicates the presence of positively selected sites.
  4. 4 Number of codons under positive selection detected by the model showing the highest likelihood (indicated in parentheses) of PAML (P < 0.05).
  5. 5 Number of codons under positive selection changed on the branch of the group A-B boundary according to PAML using the model described in nM column.
  6. 6 Number of codons under positive selection according to TreeSAAP [35].
  7. 7 Number of codons under positive selection changed on the branch of the group A-B boundary according to TreeSAAP.
