Abstract

In this study, the complete mitochondrial genome sequence of the Liuyang black goat was investigated, and phylogenetic relationships between the Liuyang black goat and other species of Caprinae were analyzed. The total length of the mitochondrial genome was 16,715 bp, which consisted of 33.50% A, 27.27% T, 25.98% C, and 13.25% G. The mitochondrial genome contained a major non-coding control region (D-loop region), two ribosomal RNA genes, 13 protein-coding genes, and 22 transfer RNA genes. Neighbor-joining and maximum-parsimony trees of Caprinae constructed using 13 mitochondrial protein-coding genes showed that the Liuyang black goat is phylogenetically closest to Hemitragus jemlahicus (the Himalayan tahr) and Blue sheep to form clade A. Tibetan antelopes clustered separately in clade B and so did sheep in clade C.
