摘　　要：为确定SYNJ1基因与牛、羊角的关联性,利用PCR-SSCP技术并以3个牛品种(荷斯坦奶牛(有角)、安格斯牛(无角)、海福特牛(无角))以及3个不同角型的羊品种河北小尾寒羊(无角)、无角道赛特、杂种蒙古羊(有角、无角)为样本,对SYNJ1基因进行了分析。结果表明:未发现SYNJ1基因C3981T位点的SNP与牛、绵羊角的有无存在关联。将不同角型的牛、羊PCR产物进行测序,经过比对也没有发现突变位点,只是牛羊品种间存在一个C-T突变。关于控制牛、绵羊角的基因,还需进行更加深入的研究。In order to define the relationship between the SYNJ1 gene and cattle or sheep having horns or not,the SYNJ1 gene in three cattle breeds：Holsteins,Angus,and Hareford and three sheep breeds：Small fat-tail sheep of Hebei,Poll Dorset,and Hybrid Mongolian sheep,which show different horn traits,was analyzed by PCR-SSCP.The results indicated that the SYNJ1 gene was not associated to the cattle and sheep horned/polled trait.Except for a C-T SNP existed between breeds of cattle and sheep,other SNP sites were not found.The results indicate that deep researches on the gene which control horns in Bos taurus and Ovis aries need to be further investigated.
