The complete mitochondrial genome sequence of the Datong yak (Bos grunniens)

Abstract

Datong yak is a famous artificially cultivated breed in China. In the present work, we report the complete mitochondrial genome sequence of Datong yak for the first time. The total length of the mitogenome is 16,323 bp long, containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one non-coding region (D-loop region). The gene order of Datong yak mitogenome is identical to that observed in most other vertebrates. The overall base composition is 33.71% A, 25.8.0% C, 13.21% G and 27.27% T, with an A + T content of 60.98%. The complete mitogenome sequence information of Datong yak can provide useful data for further studies on molecular breeding and taxonomic status.

Notice of Correction:

In the original version of this article, published online ahead of print on 24 March 2014, the base composition was written incorrectly in the abstract. Additionally, in Table 1, two stop codons were corrected to read ‘T- -’ for genes COX3 and ND3. Both errors have been corrected in this version. The authors and editors apologize for any inconvenience caused.
