The complete mitochondrial genome of the Mayang white goose and its phylogenetic analyses

Abstract

Mayang white goose (MYW) is one of the famous indigenous breeds of Hunan province in China. It is the first time that the complete mitochondrial genome sequence of the MYW was reported. The total length of the mtDNA is 16,738 bp. It contains the typical structure, including 22 transfer RNA genes, two ribosomal RNA genes, 13 protein-coding genes, and one non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 30.12% for A, 22.58% for T, 32.11% for C, and 15.18% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 23 Anseriform species are divided into four major clades: Anatinae, Anserinae, Dendrocygninae, and Anseranatidae. In addition, our work confirmed that MYW is different from other goose species in Hunan province in that it has a close genetic relationship with fellow tribal members Anser fabalis and Anser anser. This work will provide an important data set for the study in the genetic mechanism of goose in Hunan province.
