The complete mitochondrial genome of Zhangmu cattle (Bos taurus)

The Zhangmu cattle (Bos taurus) is a rare breed native to the central Himalayas, which has recently suffered drastic reduction in its population. In the present study, the complete mitochondrial genome of Zhangmu cattle was determined. The 16,340 bp circular mitochondrial genome contained a common set of 37 mitochondrial genes, including 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. The gene order was identical to that of other B. taurus breeds. The overall base composition of this genome was as follows: 33.4% A, 26.0% C, 27.2% T and 13.4% G, with a total A+T content of 60.6%. Both phylogenetic trees based on the maximum likelihood and neighbor joining methods showed that Zhangmu cattle was grouped with other Asian breeds such as Korean cattle.
