The common bean (Phaseolus vulgaris L.) is the most consumed food legume in the world and is a major source of dietary protein, carbohydrates, and valuable micronutrients, especially in developing countries. Diversity Arrays Technology (DArTseq), based on genome reduction with restriction enzymes, provides a rapid, high-throughput, and cost-effective tool capable of generating thousands of genotyped single nucleotide polymorphisms (SNPs) for a genome-wide analysis of genetic diversity. In this study, we aimed to characterize common bean accessions using SNPs detected by a DArTseq approach. A total of 43,018 SNPs were identified from 173 common bean accessions, including Andean and Mesoamerican genotypes. After filtering raw and redundant data, a total of 16,366 SNPs were considered for further analyses. According to population structure analysis, the genotypes were roughly divided into 2 gene pools of Andean and Mesoamerican types. Pairwise fixation index (Fst) values were calculated to resolve the differentiation between populations. This study demonstrated that discovering SNPs from the whole genome is a potential resource for identifying naturally diverse accessions and also the information could be used in breeding programs to develop new common bean varieties.

İncele - MakaleAçık Erişim2017Scopus SJRQ4Association of IGF and IGFBP2 gene polymorphisms with growth and egg traits in Atak-S laying hens

Atak-S laying hens are a high-performance hybrid obtained by crossing of the Rhode Island Red (RIR) X the Barred Plymouth Rock (BR) and are being produced in the Ankara Poultry Research Institute since 1997. Phenotypic and genetic improving studies are continuous for this hybrid. In this study three different SNPs, two from IGF1 and one from IGFBP2 genes, were examined in 150 Atak-S chickens. Genetic association of SNPs were compared to body weight and egg number till 32 weeks of age, body weight at sexual maturity, age at sexual maturity and also egg quality traits such as egg shell breaking strength, shell thickness, Haugh unit, albumen index, yolk index and shape index were statistically analyzed. Only IGF1(a) locus was in agreement with Hardy-Weinberg equilibrium, while, the rest of the loci were not. As a result of the comparisons performed to the three SNPs, it was determined that there was a significant association (P < 0.05) between the T364C haplotypes of the IGF1(b) locus and body weight at 32 weeks of age, but there was not any association to the other traits.
