Abbreviations: GST, interpopulation differentiation; G′ST, the standardized GST; HS, average gene diversity within populations; HT, total gene diversity; mtDNA, mitochondrial DNA; ptDNA, plastid DNA; NST, the number of substitution types. *NST is significantly different from GST (P<0.05); NS indicates that NST is not significantly different from GST.
