Wugangtong white goose is one of the famous native breed in Hunan province of China. In this study, the complete mitochondrial genome sequence of the Wugangtong white goose was reported in Hunan Province first, which was determined through PCR-based method. The total length of the mitogenome is 16,741 bp. It contains the typical structure, including 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes and 1 non-coding control region (D-loop region) as that of most other vertebrates. The overall composition of the mitogenome was estimated to be 30.22% for A, 22.69% for T, 32.02% for C and 15.06% for G. All the protein initiation codons are ATG, except for COX1, COX2 and ND5 are GTG, ND6 is CTA. The complete mitochondrial genome sequence of the Wugangtong white goose will provide an important data set for the study in genetic mechanism of Wugangtong goose in Hunan province.

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]
