Phylogenetic studies of four Anser cygnoides (Anserini: Anserinae) 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 goose, Anser cygnoides populations from three different areas of Hunan province in China. The Anser cygnoides breed Wugangtong white goose (WGTW) sample and Wugangtong grey goose sample (WGTG) were taken from the Wugang county of Shaoyang city, the Anser cygnoides breed Xupu goose (XP) sample was taken from the Xupu county of Huaihua city, and the Anser cygnoides breed Yanling white goose (YLW) sample was taken from the Yanling county of Zhuzhou city. The organization of the four Anser cygnoides breeds mitochondrial genomes was similar. Phylogenetic analyses using N-J computational algorithms showed that the analyzed species are divided into four major clades: Anatinae, Anserinae, Dendrocygninae and Anseranatidae. It was noted that Wugangtong white goose, Yanling white goose and Xupu goose have highly similar phylogenetic relationship.
