Abstract

Three single nucleotide polymorphisms (SNPs) in the porcine . MYOD1 gene were used for association analysis and haplotype construction to evaluate the effects of their substitution. Four hundred and three pigs of Yorkshire and Berkshire breeds were used. The mRNA expression levels of . MYOD1 were examined. The g.489. C. >. T and g.1264. C. >. A SNPs were significantly associated with several muscle fiber characteristics, the loin eye area, and lightness. Particularly, animals having hetero-genotypes of both sites showed good performance both in lean meat production and meat quality traits. The results of haplotype substitution were similar to the associations of individual SNPs. Moreover, the 2 SNPs had significant effects on mRNA expression. Therefore, the g.489. C. >. T and g.1264. C. >. A SNPs in . MYOD1 may be meaningful DNA markers that can be used for improving important porcine economic traits.
