| 摘 要： | 瘦肉率是猪育种中重要的目标性状之一 ,其大小与骨骼肌的量密切相关。猪抑肌素基因是与瘦肉率有关的基因之一 ,本研究以大白、长白、杜洛克、民猪、三江白猪和军牧Ⅰ号为研究对象 ,采用限制性酶切片段生长度多态性 (RFLP)分子标记法对抑肌素基因的启动区进行了酶切多态性分析。结果表明 :大白、长白、杜洛克以等位基因T为主 :三江白猪和军牧Ⅰ号全部是TT型 ;民猪 3种基因型均有且频率近乎相等

| Abstract: | Lean meat percentage is one of the most important economic traits in pig breeding programs.Myostatin,which is a new member of TGF beta superfamily,was identified by McPherron as a negative regulator of skeletal muscle mass in mice and was related to lean meat percentage.The present study analyzed the polymorphisms of porcine mysotatin gene in promoter region among different breeds including Yorkshire,Landrace,Duroc,JunmuⅠpig,Min pig and Sanjiang pig by PCR?RFLPs.The allele T dominated in the imported lean type pig breeds such as Yorkshire,Landrace and Duroc.No allele A was detected in JunmuⅠpig and Sanjiang pig,and the frequencies of genotypes were about equal in Min pig. |
