摘要: Sunan yak is one of the unique and indigenous yak species in China. The complete mitochondrial genome sequence of the Sunan yak was first determined in this study. The mitochondrial DNA is a circular molecule with 16,322 by in length, containing 12 protein-coding genes, two rRNA genes, 22 tRNA genes and a noncoding control region (D-loop), showed a typical mammal pattern. The overall nucleotide composition is A (33.71%), T(27.26%), C(25.82%), G(13.21%) with an A + T content of 60.97%. Phylogenetic analysis based on the mitochondrial genomes of 12 related species using MEGA 5.0 indicated that Sunan yak was most closely related to Qinghai Plateau yak and Maiwa yak.
