PaLi yak is a very important local breed in China; as a year-round grazing animal, it plays a very important role for the economic and native herdsmen. The PaLi yak complete mitochondrial DNA is sequenced in this study, the total length is 16,324 bp, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region (D-loop region). The order and composition are similar to most of the other vertebrates. The base contents are: 33.72% A, 25.80% C, 13.21% G and 27.27% T; A + T (60.99%) was higher than G + C (39.01%). The phylogenetic relationships were analyzed using the complete mitogenome sequence, results showed that the genetic relationship between yak and cattle is distinct. These information provides useful data for further study on protection of genetic resources and the taxonomy of Bovinae.
