Dayu yak () is a long-furred yak breed from the Qinghai-Tibetan Plateau, and is highly adapted to local high-altitude and cold environments. In this study, its mitochondrial genome was characterized via high-throughput sequencing technology. The genome is 16,323 bp long with an AT-biased base composition (61.0% A + T; light strand), and harbors the typical set of 37 mitochondrial genes and a noncoding control region. Its gene arrangement is identical to those of other bovid taxa. Phylogenetic analysis suggests that Dayu yak is most closely related to Maiwa, Niangya, Qinghai Plateau, Xueduo and Yushu yaks.
大禹牦牛是一种来自青藏高原的长毛牦牛品种，对当地高海拔和寒冷环境具有高度适应性。在本研究中，通过高通量测序技术对其线粒体基因组进行了表征。该基因组长度为16323 bp，碱基组成偏向AT（轻链中A+T占61.0%），包含一组典型的37个线粒体基因和一个非编码控制区。其基因排列与其他牛科类群相同。系统发育分析表明，大禹牦牛与麦洼、娘亚、青海高原、雪多和玉树牦牛关系最为密切。
