MSTN基因外显子3的多态性及其与边鸡生长性状的关联分析
Polymorphisms in Exon 3 of the Myostatin Gene and its Relationship with Growth Traits in Bian Chicken
摘要
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 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).关键词
