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.
凉山猪是中国四川省著名的本地品种之一。它生活在山区(海拔约1500 - 2500米),肉质优良。在此,首次报道了凉山猪的完整线粒体基因组序列。线粒体基因组全长16760 bp,其中A占34.62%,T占25.79%,C占26.20%,G占13.39%,A + T偏倚率为60.41%。线粒体基因组包含一个主要的非编码控制区(D - 环区)、两个核糖体RNA基因、13个蛋白质编码基因(PCGs)和22个转移RNA基因。D - 环区位于tRNA - Pro和tRNA - Phe基因之间,长度为1324 bp,该区域发现了一些串联重复序列。凉山猪的线粒体基因组在遗传机制中发挥着重要作用。
