绵羊是最重要和普遍的家畜之一。然而,大多数绵羊品种的起源知之甚少,特别是大尾羊的母系起源于特定的群体。该研究中,报道了乌珠穆沁羊(绵羊)整个线粒体DNA,其来源于中国最古老的一种肥尾绵羊品种之一——中国蒙古羊。它有2个核糖体RNA基因、13个蛋白质编码基因、22个转运RNA基因,和D-loop区。 线粒体基因组全长16 617bp,乌珠穆沁羊的线粒体基因组与特克塞尔羊之间的同源性为50%。乌珠穆沁羊的线粒体DNA序列的揭示将在进一步研究绵羊的进化和驯化中发挥重要作用。 原文摘要如下: Characterization of the complete mitochondrial genome sequence of Ujumuqin sheep (Ovis aries) Yang C1, Li L1, Zhong T1, Wang L1, Zhang H1 Abstract:Sheep is one of the most important and widespread domestic animals. Nevertheless, the origins of most sheep breeds are poorly understood, specifically the fat-tailed sheep that maternally originates from a specific group. Here, we reported the whole mitochondrial DNA of Ujumuqin sheep (Ovis aries), derived from one of the oldest fat-tailed sheep breed-Mongolian sheep in Keywords: Fat-tailed sheep, Ovis aries, Ujumuqin sheep, mitogenome 相关信息: |
