Phylogenetic studies of two Anas platyrhynchos (Anatini: Anatinae) in Hunan province of China based on complete mitochondrial DNA sequences

Abstract

In this study, we cloned and sequenced the complete mitochondrial DNAs of Chinese duck, Anas platyrhynchos, population from two different areas of Hunan province in China. The Anas platyrhynchos breed Linwu duck (LW) sample was taken from the Linwu county of Chenzhou city, and the Anas platyrhynchos breed Youxian duck (YX) sample was taken from the Youxian county of Zhuzhou city. The lengths of their complete mitochondrial genome were 16,604 bp (LW) and 16,606 bp (YX), respectively. The organization of the two Anas platyrhynchos breed mitochondrial genomes was similar to those reported from other duck mitochondrial genomes. Phylogenetic analyses using N–J computational algorithms showed that the analyzed species are divided into four major clades: Anatinae, Anserinae, Dendrocygninae and Anseranatidae. Also, the Linwu duck and Youxian duck have highly similar phylogenetic relationship.
