Golmud yak (Bos grunniens) is mainly lived in the southern Qaidam Basin in Qinghai Province, China. Here, the complete mitogenome of the Golmud yak was fi rstly sequenced using Illumina high-throughput sequencing technique and the corresponding sequence characterization also has been identified. Th e mitogenome of Golmud yak was 16,324 bp length with an A + T-biased nucleotide composition (60.97%). It includes 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes and a control region (D-loop region), which is consistent with that of other bovine species. Th e phylogenetic tree showed that Golmud yak was most closely related to Sibu, Huanhu, Zhongdian, Ashdan, Jiulong, Pali, Datong and Bazhou yak breeds, closer to Yushu, Niangya, Qinghai-Gaoyuan, Xueduo, Maiwa and wild yak, but far away from other yak breeds (i.e. Jinchuan, Gannan and Tianzhu white yak). Th e complete mitogenome sequence reported here would provide valuable information for breeding and improvement of Golmud yak. |
