Phylogenetic studies of four Anser cygnoides (Anserini: Anserinae) in Hunan province of China based on complete mitochondrial DNA sequences.

In this study, we cloned and sequenced the complete mitochondrial DNAs of Chinese goose,Anser cygnoidespopulations from three different areas of Hunan province in China. TheAnser cygnoidesbreed Wugangtong white goose (WGTW) sample and Wugangtong grey goose sample (WGTG) were taken from the Wugang county of Shaoyang city, theAnser cygnoidesbreed Xupu goose (XP) sample was taken from the Xupu county of Huaihua city, and theAnser cygnoidesbreed Yanling white goose (YLW) sample was taken from the Yanling county of Zhuzhou city. The organization of the fourAnser cygnoidesbreeds 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. [ABSTRACT FROM AUTHOR]
