Abstract


We identified molecular markers associated with meat-quality traits in the porcine RPL27A (ribosomal protein L27a) gene. Three single nucleotide polymorphisms (SNPs) were discovered in the porcine RPL27A gene: g.920T>C, g.1013T>C, and g.1046T>C. The g.920 T>C SNP was significantly associated with pH24 (P < 0.05) and collagen (P < 0.05), while the g.1013T>C and g.1046T>C SNPs were significantly associated with moisture (P < 0.05). Either the TTT or CCC haplotype was significantly associated with moisture, pH24 and collagen (P < 0.05, respectively). The genotypes of RPL27A associated with meat-quality traits were all located in intron 2. The three SNPs of the RPL27A found in this study will provide useful information for genetic characterization or association studies of meat-quality traits in other populations. Additionally, these markers could potentially be applied in pig breeding programs to improve meat-quality traits after validation in other populations.
