Abstract
Abstract
Discrepancies in geographic variation patterns between nuclear DNA and mitochondrial DNA (mtDNA) are the result of the complicated differentiation processes in organisms and are the key to understanding their true evolutionary processes. The genetic differentiation of the northern and Southern-Izu lineages of the Japanese newt, Cynops pyrrhogaster, was investigated through their single nucleotide polymorphism variations obtained via multiplexed ISSR genotyping by sequencing (MIG-seq). We found three genetic groups (Tohoku, N-Kanto and S-Kanto), that were not detected by mtDNA variations, in the northern lineage. N-Kanto has intermediate genetic characteristics between Tohoku and S-Kanto. The genetic groups are now moderately isolated from each other and have unique genetic characteristics. An estimation of the evolutionary history using the approximate Bayesian computation (ABC) approach suggested that Tohoku diverged from the common ancestor of S-Kanto and S-Izu. Then, S-Kanto and S-Izu split, and the recent hybridization between Tohoku and S-Kanto gave rise to N-Kanto. The origin of N-Kanto through the hybridization is relatively young and seems to be related to changes in the distributions of Tohoku and S-Kanto as a result of climatic oscillation in the Pleistocene. We conclude that the mitochondrial genome of S-Kanto was captured in Tohoku and that the original mitochondrial genome of Tohoku was entirely removed through hybridization.
