Study on the Polymorphisms of Porcine Myostatin Gene in Promoter Region by PCR-RFLPS     

YANGXiu-qin LIUDi 《东北农业大学学报(英文版)》2005,12(1):65-67

In order to further study functions of the porcine myostatin gene, we analyzed the polymorphisms of porcine myostatin gene in promoter region among different breeds including Yorkshire, Landrace, Duroc, Junmu, Min pig and Sanjiang white 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 Junmu and Sanjiang white pig, and the frequencies of three genotypes were about equal in Min pig. The result using X^2 analysis showed that the distribution of three genotypes was related to pig breeds.  相似文献
