为探究绵羊GDF9基因编码区多态性与繁殖性能的遗传效应,以杜泊羊、滩寒羊、杂一代、杂二代和横交一代5个绵羊群体为研究对象,利用Sequenom Mass ARRAY? SNP技术对5个绵羊群体GDF9基因的4个错义突变位点进行检测,并与产羔数进行关联分析...为探究绵羊GDF9基因编码区多态性与繁殖性能的遗传效应,以杜泊羊、滩寒羊、杂一代、杂二代和横交一代5个绵羊群体为研究对象,利用Sequenom Mass ARRAY? SNP技术对5个绵羊群体GDF9基因的4个错义突变位点进行检测,并与产羔数进行关联分析。结果显示,rs425223128、rs597009987和rs415699275位点基因型均为纯合型,rs160076408位点在5个群体中存在CC、TC、TT等3种基因型。对rs 160076408位点不同基因型与5个群体的产羔数进行关联分析,结果表明,rs160076408位点在杂一代群体中与产羔数有一定的关联性,其中TC基因型产羔数显著高于CC基因型(P<0.05)。可见,rs160076408位点适用于杂一代绵羊群体多羔性状的选育。生物信息学分析表明,绵羊GDF9蛋白理论等电点为9.08,不稳定系数为54.43,为不稳定的碱性蛋白;脂肪系数为77.31,总平均亲水性为-0.404。rs 160076408位点突变前后GDF9蛋白的二级结构类型发生了变化。蛋白质互作网络分析表明,GDF9蛋白与调控动物繁殖的相关蛋白质互作。展开更多
