Characterization of the complete mitochondrial genome of Tibet Gaoshan Yak (Bos grunniens)

Tibet Gaoshan Yak (Bos grunniens) is a local Yak breed that mainly produces meat in Tibet Autonomous Region, China. In this study, the complete mitochondrial genome of Tibet Gaoshan Yak was sequenced. The total length of the mitochondrial genome is 16,323 bp, and the base composition is 33.71% for A, 13.21% for G, 27.27% for T, and 25.81% for C. The genome includes 13 protein-coding genes (ND1-ND6, ND4L, COX1-COX3, ATP6, ATP8, and CYTB), two rRNA genes (12S rRNA and 16SrRNA), 22 tRNA genes, and a noncoding control region (D-loop). Phylogenetic analysis showed that Tibet Gaoshan Yak has the closest relationship with Polled Yak. The sequence analysis provided in this study will be helpful to the management of Yak breeds, the origin, and evolution of Yak, and the protection and utilization of genetic resources.

Automated summary

The study sequenced the complete mitochondrial genome of Tibet Gaoshan Yak, revealing its closest relationship with Polled Yak. This sequence analysis will be helpful for the management of Yak breeds and the conservation of genetic resources.
