Mithun (Bos frontalis) is an endangered domestic bovine species native to the hilly areas of China, Bangladesh, Myanmar, Bhutan and India. It is believed to have been domesticated from gaur around 8000 years ago. However, a few studies suggest that mithun is either an independent species or a hybrid descendant of gaur and cattle. Therefore, to understand the evolutionary history of mithun, the complete mitochondrial genome of Indian mithun was sequenced and compared with the mitochondrial genome of closely related Bos species. The mitochondrial genome of mithun was 16,346 bp long and consisted of 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and a control region. The phylogenetic assessments of Indian mithun along with other Bos species showed a very close genetic relationship of Indian mithun with gaur suggesting that Indian mithun might have evolved from gaur.
大额牛（Bos frontalis）是一种原产于中国、孟加拉国、缅甸、不丹和印度山区的濒危家养牛种。据信它大约在8000年前从白肢野牛驯化而来。然而，一些研究表明大额牛要么是一个独立物种，要么是白肢野牛和牛的杂交后代。因此，为了了解大额牛的进化历史，对印度大额牛的完整线粒体基因组进行了测序，并与亲缘关系密切的牛属物种的线粒体基因组进行了比较。大额牛的线粒体基因组长度为16346bp，由22个tRNA基因、13个蛋白质编码基因、2个rRNA基因和一个控制区组成。对印度大额牛和其他牛属物种的系统发育评估表明，印度大额牛与白肢野牛的遗传关系非常密切，这表明印度大额牛可能是由白肢野牛进化而来的。
