^a One promoter region for each CBF was excluded because of long sequence indels (see "Materials and methods"); ^b Only CDS regions were analyzed (accession nos.: EF523160~EF523192); n, number of sequences analyzed; L, aligned sequence length; L-gaps, sequence length without missing data; H, number of haplotypes; S, number of segregated sites; π, nucleotide diversity estimated by pair-wise comparisons from all sites; π_syn, nucleotide diversity estimated from synonymous sites; π_nonsyn, nucleotide diversity estimated from nonsynonymous sites; θ_W, nucleotide diversity estimated based on segregating sites from all sites. ^# p < 0.1; * p < 0.05; ** p < 0.01; N.S., not significant.
