Abstract
The MYLPF gene encodes fast myosin regulatory light chain, and is a positional and functional candidate gene for meat quality. The aim of this study was to identify associations between SNPs in the promoter region of the porcine MYLPF gene and meat quality traits. A total of 22 SNPs were identified in a population of crossbred animals (n=86) and based on minor allele frequency and proximity to the transcription start site, five SNPs were genotyped in purebred; Large White (n=98), Duroc (n=99) and Pietrain (n=98) pigs. No associations were observed in the Pietrain breed, while the Duroc breed was almost monomorphic for all SNPs. In the Large White breed SNP g-1314A>G and linked SNPS g.-871T>G, g.-566T>C, g.-403C>G were associated with ultimate pH and driploss (P<0.05). This study identified associations between MYLPF and meat quality and highlights the importance of considering the genetic background within gene-assisted selection programmes.

Association of Apolipoprotein B and Adiponectin Receptor 1 Genes with Carcass, Bone Integrity and Performance Traits in a Paternal Broiler Line. PLoS One 2015; 10:e0136824.

Abstract
Apolipoprotein B (APOB) and Adiponectin Receptor 1 (ADIPOR1) are related to the regulation of feed intake, fat metabolism and protein deposition and are candidate genes for genomic studies in birds. In this study, associations of two single nucleotide polymorphisms (SNPs) g.102A>T (APOB) and g.729C>T (ADIPOR1) with carcass, bone integrity and performance traits in broilers were investigated. Genotyping was performed on a paternal line of 1,454 broilers. The SNP detection was carried out by PCR-RFLP technique using the restriction enzymes HhaI for the SNP g.729C>T and MslI for the SNP g.102A>T. The association analyses of the two SNPs with 85 traits were performed using the restricted maximum likelihood (REML) and Generalized Quasi-Likelihood Score (GQLS) methods. For REML the model included the random additive genetic effect of animal and fixed effects of sex, hatch and SNP genotypes. In the GQLS method, a logistic regression was used to associate the genotypes with phenotypes adjusted for fixed effects of sex and hatch. The SNP g.729C>T in the ADIPOR1 gene was associated with thickness of the femur and breast skin yield. Thus, the ADIPOR1 gene seems implicated in the metabolism and/or fat deposition and bone integrity in broilers.
