K, estimated number of substitutions per nucleotide site and its standard deviation. K is based on the γ-K2P model for LTR (Kimura, 1980). The average substitution rate of 6.5 × 10−9 substitutions per synonymous site per year that was estimated for the adh1 and adh2 genes in maize (Gaut et al., 1996) was applied to estimate the divergence time.
