Abstract

We sequenced the 16S rRNA gene in mitochondrial DNA to characterize mithun located in Bhutan and to increase our understanding of its origin. We compared mithun with yak, European cattle, Bhutanese zebu and Indian zebu. Sequencing revealed low nucleotide diversity within the mithun population and their phylogenetic proximity to gaur. A close relationship between Bhutanese mithun and gaur was confirmed by an additional comparison with wild gaur specimens from three locations in Bhutan. Direct domestication of mithun from gaur was supported, while maternal contribution from the cattle lineage during domestication was not supported.

摘要

我们对线粒体 DNA 中的 16S rRNA 基因进行了测序，以描述位于不丹的野牛，并增进我们对其起源的了解。我们将野牛与牦牛、欧洲牛、不丹牛和印度瘤牛进行了比较。测序结果显示，野牛种群内的核苷酸多样性较低，与爪哇野牛的亲缘关系较近。通过与不丹三个地区的野生爪哇野牛标本进行额外比较，进一步证实了不丹野牛与爪哇野牛之间的密切关系。这支持了野牛直接被驯化为野牛，而在驯化过程中牛科动物的母系贡献不被支持。
