Abstract
The population of domestic yak, Tianzhu white yak, from Tibetan area in China is considered as a rare Bos grunniens species. We first determined and annotated its complete mitochondrial genome. The mitogenome is 16,319 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and a control region. As in other mammals, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes, which are encoded on the light strand. Its overall base composition is A: 33.7%, T: 27.2%, C: 25.8% and G: 13.2%. The complete mitogenome of the new subspecies of Bos grunniens could provide an important data to further explore the taxonomic status of the subspecies.
