This study determined the population structure and genome-wide marker-trait association of agronomic traits of wheat for drought-tolerance breeding. Ninety-three diverse bread wheat genotypes were genotyped using the Diversity Arrays Technology sequencing (DArTseq) protocol. The number of days-to-heading (DTH), number of days-to-maturity (DTM), plant height (PHT), spike length (SPL), number of ...

Tilapia is an economically important fish in the world. High mortality caused by low temperature a serious problem to tilapia farming during overwintering. In this study, genome-wide significant QTL interval, located on chrLG18, controlling cold-tolerance trait was identified full-sib family of GIFT originated line using ddRAD-seq-based mapping. The explained 21.5% phenotypic variances. Six pai...

the genotypes of the melatonin receptor 1a (mtnr1a) were determined by pcr-rflp in the native iranian shall  and karakul breeds of sheep . blood samples were collected from 60 karakul and 50 shall breeds. genomic dna was extracted based on the guanidin thiocyanate-slica gel method. after pcr reaction, pcr products were digested by the mnl1 restriction enzyme. the mtnr1a locus had two genotypes ...

Pacific abalone ( Haliotis discus hannai ) is a commercially important high valued molluscan species. Its wild population has decreased in recent years. It widely cultured Korea. Traditional breeding programs have been implemented for hatchery production of seeds. To obtain more genetic information its molecular program, high-density linkage map and quantitative trait locus (QTL) three growth-r...

The genetic improvement of production traits can be made through marker assisted selection using a candidategene approach. Bone morphogenetic proteins (BMPs) are multifunctional growth factors that belong to thetransforming factor b (TGF-b) superfamily. This study aimed detect the polymorphism BMP-4in different goat breeds by polymerase chain reaction-single strand confirmational (PCR-SSCP) and...

quantitative trait loci (qtl) affecting milk production traits on bovine chromosome 6 close to the opn gene location have been identified through several whole genome scans. opn is a phosphoprotein, synthesized in a variety of tissues and cells and secreted into body fluids. in this study, dna was isolated from blood samples collected from 398 holstein cows in tehran and esfahan provinces. dna ...
