Association mapping is usually performed by testing the correlation between a single marker and phenotypes. However, because patterns of variation within genomes are inherited as blocks, clustering markers into haplotypes for genome-wide scans could be a worthwhile approach to improve statistical power to detect associations. The availability of high-density molecular data allows the possibilit...
Arrayor chip-based single nucleotide polymorphism (SNP) markers are widely used in genomic studies because of their abundance in a genome and lower cost per data point than older marker technologies. Genotyping-bysequencing (GBS), a relatively newer approach of genotyping, suggests equal appeal because of its lesser cost per data point and the avoidance of ascertainment bias during genotyping. ...
The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey,...
Optimization of root system architecture (RSA) traits is an important objective for modern wheat breeding. Linkage and association mapping for RSA in two recombinant inbred line populations and one association mapping panel of 183 elite durum wheat (Triticum turgidum L. var. durum Desf.) accessions evaluated as seedlings grown on filter paper/polycarbonate screening plates revealed 20 clusters ...
The nucleocapsid protein of bovine rotavirus was shown to exist in trimeric units in both the virus particle and in infected cells, with the subunits linked by non-covalent interactions. These trimeric units complex further by disulphide bridges into larger units which may represent the hexameric structures observed by electron microscopy. Visualization of various nucleocapsid protein complexes...
The production and cultivation of hybrid wheat is a possible strategy to close the yield gap in wheat. Efficient hybrid wheat seed production largely depends on high rates of cross-pollination which can be ensured through high anther extrusion (AE) by male parental lines. Here, we report the AE capacity and elucidate its genetics in 514 elite European winter wheat varieties via genome-wide asso...
شناسایی مناطق ژنومی که هدف انتخاب بوده اند، از بحث برانگیزترین مباحث در حوزة تحقیقات ژنتیک حیوانی، به خصوص در حیوانات اهلی است. در این مطالعه، پویش کل ژنوم برای شناسایی مناطقی از ژنوم که در گاومیش های خوزستانی و مازندرانی هدف انتخاب های طبیعی یا مصنوعی قرار گرفته اند، اجرا شده است. بدین منظور 148 رأس گاومیش رودخانه ای شامل جمعیت های خوزستانی (121 رأس) و مازندرانی (27 رأس)، به وسیلة آرایه های ژن...
Dairy heifers were subjected to a non-life-threatening challenge designed to induce ruminal acidosis by feeding grain and sugar. Large among animal variation in clinical signs of acidosis, rumen metabolite concentrations, and the rumen microbiome occurred. This exploratory study investigates sources of the variation by examining associations between the genome, metabolome, and microbiome, albei...
The Gd(Ba2-xPrx)Cu3O single phase polycrystalline samples with 0.00 ≤ x ≤ 1.00 were investigated for structural, electronic and flux dynamic properties. An unusual hump on the resistivity vs. temperature curve of the samples has been observed for particular values of Pr doping. We have found that the Ba atom substitution at the rare earth site could lead to superconductivity in some parts of ...
