摘  要:
针对牛肌肉生长抑制素基因编码区设计引物,以PCR扩增及测序的方法,检测了新疆巴音布鲁克自治区的18头蒙古牛样本。结果显示:蒙古牛肌肉生长抑制素基因编码区含1128个碱基对。通过比对,在所检蒙古牛样本中,存在1个核苷酸多态位点,含有2种核苷酸类型(C 55.6%和T 44.4%);在该位点上,欧洲牛(T)、瘤牛(C)和牦牛(C)均为单型。说明了蒙古牛与欧洲牛、瘤牛和/或牦牛三者间存在一定的基因交流,但根据本研究无法确定蒙古牛是与瘤牛,还是与牦牛发生基因交流。

摘  要:
3 sets of primers were adopted to detect the polymorphism of myostatin gene in 18 Menggu Cattle from Xinjiang by PCR methed.The results showed that,1128 base pairs existed in myostatin gene ceding region and 1 polymorphic site(414)was observed with 10 C(55.6%)and 8 T(44.4%)in the 18 samples,while European normal cattle,zebu and yak hold on this site a haplotype each,T,C,C,respectively.The findings indicated that Menggu Cattle communicate genetically with European normal cattle,zebu and/or yak,but to determine the communication between Menggu Cattle and zebu and/or yak needs further evidence.
