Article Influence of SCD and FABP3 Genetic Markers on Carcass Traits and Meat Quality in Aberdeen Angus Bulls(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2025) Ardicli, Sena; Senturk, Nursen; Selvi, Tugce Necla; Yonga, Sena; Celik, Rumeysa; Karalar, Beyza; Ustuner, HakanThis study evaluated the association of stearoyl-CoA desaturase (SCD) and fatty acid-binding protein 3 (FABP3) gene polymorphisms with carcass and meat quality traits in Aberdeen Angus bulls. Two hundred seventy-four Angus bulls were genotyped using PCR-RFLP and Sanger sequencing. Next, the association of SCD and FABP3 genetic variants with traits such as live weight, average daily weight gain, carcass weight (both hot and cold), dressing percentage, carcass length, back fat thickness, carcass color score, pH, and marbling score was analyzed. Significant differences were observed in average daily weight gain among different FABP3 genotypes, with the GG genotype showing the highest gains (P<0.01). Furthermore, novel associations between the SCD x FABP3 interaction and key traits were identified, including dressing percentage and carcass pH. Notably, an epistatic pattern through this genotypic interaction was demonstrated, which may significantly influence postmortem pH decline in beef cattle. The results suggest a notable impact of the FABP3 rs210042291 gene on growth rates. These findings highlight the complexity of genetic influences on meat quality traits.Article Citation - WoS: 21Citation - Scopus: 23High-Throughput Single Nucleotide Polymorphism (snp) Identification and Mapping in the Sesame (sesamum Indicum L.) Genome With Genotyping by Sequencing (gbs) Analysis(Springer Verlag, 2016) Uncu, Ayşe Özgür; Frary, Anne; Karlovsky, Petr; Doğanlar, SamiSesame (Sesamum indicum L. syn. Sesamum orientale L.) is considered to be the first oil seed crop known to man. Despite its versatile use as an oil seed and a leafy vegetable, sesame is a neglected crop and has not been a subject of molecular genetic research until the last decade. There is thus limited knowledge regarding genome-specific molecular markers that are indispensible for germplasm enhancement, gene identification, and marker-assisted breeding in sesame. In this study, we employed a genotyping by sequencing (GBS) approach to a sesame recombinant inbred line (RIL) population for high-throughput single nucleotide polymorphism (SNP) identification and genotyping. A total of 15,521 SNPs were identified with 14,786 SNPs (95.26 %) located along sesame genome assembly pseudomolecules. By incorporating sesame-specific simple sequence repeat (SSR) markers developed in our previous work, 230.73 megabases (99 %) of sequence from the genome assembly were saturated with markers. This large number of markers will be available for sesame geneticists as a resource for candidate polymorphisms located along the physical chromosomes of sesame. Defining SNP loci in genome assembly sequences provides the flexibility to utilize any genotyping strategy to survey any sesame population. SNPs selected through a high stringency filtering protocol (770 SNPs) for improved map accuracy were used in conjunction with SSR markers (50 SSRs) in linkage analysis, resulting in 13 linkage groups that encompass a total genetic distance of 914 cM with 432 markers (420 SNPs, 12 SSRs). The genetic linkage map constitutes the basis for future work that will involve quantitative trait locus (QTL) analyses of metabolic and agronomic traits in the segregating RIL population.
