The complete sequence of the mitochondrial genome of Liangshan pig (Sus Scrofa).

ABSTRACT

Liangshan pig is one of the famous native breeds in Sichuan province in China. It lives in the mountainous areas (about 1500-2500 m altitude) and has a superior meat quality. Here, the complete mitochondrial genome sequence of Liangshan pig was first reported. The total length of mitochondrial genome is 16,760 bp, including 34.62% A, 25.79% T, 26.20%, C and 13.39% G, with an A + T bias of 60.41%. Mitochondrial genome contains a major non-coding control region (D-Loop region), two ribosomal RNA genes, 13 protein-coding genes (PCGs), and 22 transfer RNA genes. The D-loop region is located between the tRNA-Pro and tRNA-Phe genes with a length of 1324 bp, some tandem repeat sequences was found in the region. The mitochondrial genome of Liangshan pig provides an important role in genetic mechanism.
