title: Effect of genetic variation of CEBPA gene on body measurement and carcass traits of Qinchuan cattle.
abstract: In our study, genetic variation in coding region of cattle CCAAT enhancer binding protein alpha(namely CEBPA)gene was detected by PCR-RFLP and DNA sequencing methods in 215 individuals from Qinchuan cattle breed. Two haplotypes (A and B) and three observed genotypes (AA, AB, and BB) were detected. The result of DNA sequence showed one mutation by comparisons with NC_007316. The mutation at nt963 (T>G) were located in coding region of the CEBPA gene. Associations between the CEBPA gene genetic variation and the carcass traits were revealed in Qinchuan cattle. Least squares analysis revealed a significant statistical effect of the CEBPA gene different genotypes on slaughter weight and carcass weight in Qinchuan cattle. Individuals with BB genotype showed higher slaughter weight and carcass weight than individuals with AA and AB genotypes. Therefore, these results suggest that the CEBPA gene is a strong candidate gene that affects carcass traits in Qinchuan cattle.
