| 摘 要： | 采用PCR-SSCP技术检测边鸡及2个对照鸡群体(京海黄鸡和尤溪麻鸡)肌肉生长抑制素(myostatin,MSTN)基因外显子3的单核苷酸多态性,并与边鸡的生长性状进行相关性分析。结果表明,在MSTN基因外显子3的8527—8528 bp处检测到一个TC的插入。在边鸡和京海黄鸡中只检测到2种基因型(AA和AB基因型),在尤溪麻鸡中检测到3种基因型(AA、AB和BB基因型)。在3个鸡品种中都以A等位基因为优势等位基因。最小二乘分析结果表明,边鸡2种基因型个体的6~16周龄体重均无显著差异(P>0.05)。

| Abstract: | Single nucleotide polymorphisms(SNPs) of exon 3 of the myostatin(MSTN) gene were detected in the Bian chicken and two reference chicken populations(Jinghai and Youxi chickens) by PCR-SSCP.The relationship with growth traits in the Bian chicken was also analysed.Results showed that there exsited an insretion(TC) in the 8527 to 8528 bp of the exon 3 of the MSTN gene.Three genotypes(AB,AB and BB) were detected in the Youxi chicken,while the Bian and Jinghai chickens only displayed two genotypes(AA and AB).The ... |
