摘要： Sibu yak is famous for its excellent breed in Tibet and has become a magic way for local herdsmen to get rich. The Sibu yak, however, has been identified as an endangered bovine species. In this study, the complete mitochondrial genome of Sibu yak (Bos grunniens) was sequenced. The complete mitochondrial genome is a circular molecule with 16,324 bp in length, including 2 rRNA genes, 13 protein-coding genes, 22 tRNA genes, and a non-coding control region (D-loop). The entire nucleotide composition is A(33.70%), T(27.27%), C(25,81%), G(13.21%), respectively. Except that ND6 and 7 tRNAs (tRNA-Glu,tRNA-Pro,tRNA-Cys, tRNA-Tyr, tRNA-Ala, tRNA-Asn, and tRNA-Gln) are encoded on the light strand, the remaining genes are encoded on the heavy strand. As a valuable resource, we have compared it to related Bos species to understand the evolutionary history of Sibu yak.
