| 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 5 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—8528 bp of the exon 5 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 allele A was the predominant allele in the three chicken breeds. The least square means analysis showed the differences of body weight between the two genotypes in the Bian chicken were nonsignificant (P>0.05). |
