Classification and phylogeny of sika deer (Cervus nippon) subspecies based on the mitochondrial control region DNA sequence using an extended sample set.
To further refine the classification and phylogeny of sika deer subspecies, the well-annotated sequences of the complete mitochondrial DNA (mtDNA) control region of 13 sika deer subspecies from GenBank were downloaded, aligned and analyzed in this study. By reconstructing the phylogenetic tree with an extended sample set, the results revealed a split between Northern and Southern Mainland Asia/Taiwan lineages, and moreover, two subspecies, C.n.mantchuricus and C.n.hortulorum, were existed in Northern Mainland Asia. Unexpectedly, Dybowskii's sika deer that was thought to originate from Northern Mainland Asia joins the Southern Mainland Asia/Taiwan lineage. The genetic divergences were ranged from 2.1% to 4.7% between Dybowskii's sika deer and all the other established subspecies at the mtDNA sequence level, which suggests that the maternal lineage of uncertain sika subspecies in Europe had been maintained until today. This study also provides a better understanding for the classification, phylogeny and phylogeographic history of sika deer subspecies.
