| Abstract: | This study was aimed to research the gentic variations of ACTA1 gene in Yanbian Yellow cattle, and analyze the influence of genetic polymorphisms on meat quality traits. PCR-RFLP and PCR-SSCP technique were used to analyze the association between the polymorphisms of ACTA1 gene and meat quality traits. The results showed that there were two SNPs, A193G which with replacement of Arg by Gly amino acid, A298G which with replacement of Lys by Arg amino acid. χ2 test showed A193G and A298G were in Hardy-Weinberg equilibrium (P>0.05). The association analysis indicated that the genotypes of different mutations in ACTA1 gene were found to be significantly related to myristic acid, oleic acid, loin muscle area, marbling score (P<0.05). ACTA1 gene had potential effects on meat quality traits of Yanbian Yellow cattle, and could be used for candidate gene in early selection of new varieties of Yanbian Yellow cattle. |
