Xinong Saanen dairy goat (Capra hircus), a breed distributed widely and adapted highly in China, has the characteristics of high milk production and high litter size. Our research revealed that the complete mitochondrial genome of Xinong Saanen dairy goat was 16,639 bp in length. The contents of A, C, G and T in the mitochondrial genome were 33.6%, 26.0%, 13.1% and 27.3%, respectively. It had a typical mitogenome structure, containing 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and 1 control region. Most of the PCGs have ATG initiation codons, whereas ND2, ND3 and ND5 start with ATA. These results provide essential information for phylogeographic history and population genetic structure, genetic diversity of domestic goats and mitochondrial genome editing based on the goat model.
西农萨能奶山羊(Capra hircus)是一种在中国广泛分布且适应性很强的品种,具有高产奶量和高繁殖力的特点。我们的研究表明,西农萨能奶山羊的线粒体基因组全长16,639 bp。线粒体基因组中A、C、G和T的含量分别为33.6%、26.0%、13.1%和27.3%。它具有典型的线粒体基因组结构,包含13个蛋白质编码基因(PCGs)、2个rRNA基因、22个tRNA基因和1个控制区。大多数PCGs以ATG作为起始密码子,而ND2、ND3和ND5以ATA起始。这些结果为家养山羊的系统地理历史和群体遗传结构、遗传多样性以及基于山羊模型的线粒体基因组编辑提供了重要信息。
