  • Gene, the GenBank accession of the original unigene sequence; N, number of sampled sequences; L, length of the core alignments in which all sequences contain bases, excluding gaps; S, total number of segregating sites; h, number of unique sequences (haplotypes); πtotal and πsilent, average proportion of pairwise differences per base pair at all sites and silent sites, respectively. HKA tests: P value of the candidate genes by multiple locus HKA against the four neutral genes by the maximum cell value test. HKAtotal and HKAsilent: HKA test at all sites and silent sites, respectively. *, P < 0.05; **, P < 0.01. Candidate status: genes shown in bold are selected throughout the gene length, and genes not in bold are only selected at the 3′ region.
