Distribution of the Ka, Ks, and Ka/Ks ratio of ortholog pairs under 60-min saline treatment. (a) Distribution of Ka and Ks values of all orthologous unigenes reveals a general patten of higher Ks than Ka; (b) L-shape Ka/Ks distribution in all transcripts revealed that most homologous genes (96.9% transcripts) of two ginger species are conserved (Ka/Ks < 1); (c) L-shape distribution of genes with Ka/Ks > 1 indicate that most of the positively selective pressures for the species divergence are slight (1 < Ka/Ks < 2)
