Gannan yak is the native breed of Gansu province in China. In this work, the complete mitochondrial genome sequence of Gannan yak was determined for the first time. The total length of the mitogenome is 16,322 bp long, with the base composition of 33.74% A, 25.84% T, 13.18% C, and 27.24% G. It contained 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one non-coding region (D-loop region). The gene order of Gannan yak mitogenome is identical to that observed in most other vertebrates. The complete mitogenome sequence information of Gannan yak can provide useful data for further studies on protection of genetic resources and phylogenetic relationships within Bos grunniens.
甘南牦牛是中国甘肃省的本土品种。在本研究中，首次测定了甘南牦牛的线粒体基因组全序列。该线粒体基因组全长16322bp，碱基组成为：A占33.74%，T占25.84%，C占13.18%，G占27.24%。它包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和1个非编码区（D-loop区）。甘南牦牛线粒体基因组的基因排列顺序与大多数其他脊椎动物相同。甘南牦牛线粒体基因组全序列信息可为进一步研究牦牛遗传资源保护和系统发育关系提供有用数据。
