There is no investigation has yet been conducted for ACOX1 and CSRP3 gene polymorphisms in Korean cattle (Hanwoo), and their associations with carcass and meat quality traits. In this study, SNPs in ACOX1 and CSRP3 genes were identified and their associations with carcass and meat quality traits were investigated in 227 Hanwoo animals. Two SNPs (g.224G> A and g.19491G> A) in ACOX1 gene and one SNP (g.14859C>T) in CSRP3 gene were identified in Hanwoo and sequence analysis indicated that these SNPs were located in the coding regions. The allele frequencies of ACOX1 g.224G>A and g.19491G>A SNPs were 0.57, 0.43, and 0.56 and 0.44, respectively, For CSRP3 g.14859C>T polymorphism, the C and T allele frequencies were 0.64 and 0.36, respectively. The Hanwoo cattle were used to detect PCR-RFLP patterns for estimating the allele frequencies. Single marker association analyses were performed between genotype of each SNP, and carcass and meat quality association traits to evaluate the relationships in Hanwoo. The g.224G> A SNP genotypes of ACOX1 gene, which was significantly associated with meat quantity grade at slaughter (P< 0.03) and backfat thickness tended to be greater (P= 0.06) in Hanwoo. The previously identified g.14859C>T SNP was used in this study and the obtained genotype and allele frequencies are almost similar with the previous results reported by Bhuiyan et al. (2007). However, no significant association was found between g.19491G >A SNP in the ACOX1 and g.14859C>T SNP genotypes of CSRP3 gene and considered carcass and meat quality traits. In conclusion, the information on the identified SNPs in CSRP3 and ACOX1 genes could be useful for further association study and haplotype analysis for the development of carcass and meat quality traits in Hanwoo.
