The complete mitochondrial genome sequence of the dwarf blue sheep, Pseudois schaeferi haltenorth in China

Abstract

The dwarf blue sheep (Pseudois schaeferi haltenorth) belongs the subfamily Caprinae, which is distributed in Sichuan, Tibet, Yunnan, and Qinghai in China. In this study, the complete mitochondrial genome of Pseudois schaeferi haltenorth was sequenced. The mitogenome was 16 741 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and a non-coding control region (D-loop region). As in other mammals, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes which are encoded on the light strand. The overall base composition of the Pseudois schaeferi haltenorth is 33.54% A, 26.37% T, 26.91% C, and 13.18% G, A + T (59.91%) was higher than G + C (40.09%). The phylogenetic relationships was analyzed using the complete mitogenome sequence, results show that P. schaeferi haltenorth should be a different species differ from the Genus pseudois hodgson. These information provide useful data for further study on the protection of genetic resources and the taxonomy of Caprinae.
