高邮鸭肌肉生长抑制素基因(MSTN)5'调控区多态性与生长及腹脂率的关联分析
Association of the MSTN-5'regulatory region polymorphisms with body weights and abdominal fat rates in the Gaoyou duck
摘要
Abstract
Single nucleotide polymorphisms of MSTN 5'regulatory region of 3 different Gaoyou and 1 Shaoxing duck populations were detected using PCR-SSCP.Genetic effects of the MSTN 5'regulatory region on body weights and abdominal fat rates were analyzed.The results showed that C-G of mutations in 1046st bp of MSTN gene promoters was detected.In the test of 4 duck populations,three genotypes(CC,CG and GG gene type)were detected,and with C alleles for advantage alleles.The least square analysis results showed that different genotypes had no significant effects on week body weights.In addition,no significant differences were found among abdominal fat rates of 3 Gaoyou duck populations,while average abdominal fat rates of 3 Gaoyou duck populations were significantly greater than that of Shaoxing duck population.Different genotypes had a significant effect on abdominal fat rates of Gaoyou ducks and abdominal fat rate of the GG genotype was significantly greater than that of CG and CC type(P＜0.05).In regard to MSTN 5'regulatory region,MSTN gene,as a candidate gene of affecting abdominal fat rates,needs to be further researched.关键词
