the purpose of this research was to classify buffaloes from different areas of the two azari (west and east azarbayjan and ardabil provinces) and north (guilan province) ecotypes using support vector machine method. a total of 258 buffalo were sampled and genotyped using the axiom buffalo 90k genotyping array at the parco technologic padano lab in italy. two metric methods of cross validation a...
identification of selection targeted genomic regions is one of the most challenging areas of research in animal genetics, particularly in livestock. we carried out a genome-wide scan for signatures of positive selection to identify genomic regions that had been under selection in iranian khuzestani and mazandrani buffalo breeds. a total of 148 water buffalo from khuzestani (n=121) and mazandran...
زمینه مطالعاتی: شناسایی ژنهای بزرگ اثر، مؤثر بر صفات مهم اقتصادی یکی از مهم‌ترین اهداف اصلاح نژادی در پرورش گوسفند است. هدف: این تحقیق به منظور بررسی ساختار و لایهبندی جمعیتی و شناسایی جایگاه‌ها و ژنهای مرتبط با صفات کیفی پشم، از طریق مطالعه ارتباط ژنومی هاپلوتیپی (GWAS) با استفاده از تراشه SNP ژنوم گوسفند (Illumnia SNPChip 50K Beadchip) در یک جمعیت گوسفند زندی بود. روشکار: برای هر دام، صفا...
شناسایی مناطق ژنومی که هدف انتخاب بوده‌اند، از بحث‌برانگیزترین مباحث در حوزة تحقیقات ژنتیک حیوانی، به‌خصوص در حیوانات اهلی است. در این مطالعه، پویش کل ژنوم برای شناسایی مناطقی از ژنوم که در گاومیش‌های خوزستانی و مازندرانی هدف انتخاب‌های طبیعی یا مصنوعی قرار گرفته‌اند، اجرا شده است. بدین منظور 148 رأس گاومیش رودخانه‌ای شامل جمعیت‌های خوزستانی (121 رأس) و مازندرانی (27 رأس)، به وسیلة آرایه‌های ژن...
Device simulation, based on an extended recombination model, is used as a design tool for lifetime-controlled power diodes with different lifetime profiles. Homogenous and local recombination center profiles are considered. The sensitivity of important device properties, such as the trade-off between stationary and dynamical characteristics, to the recombination center peak position is investig...
A genome-wide association study (GWAS) for heading date (HD) was performed with a panel of 358 European winter wheat (Triticum aestivum L.) varieties and 14 spring wheat varieties through the phenotypic evaluation of HD in field tests in eight environments. Genotyping data consisted of 770 mapped microsatellite loci and 7934 mapped SNP markers derived from the 90K iSelect wheat chip. Best linea...
Genome-wide association studies (GWAS) were undertaken to identify SNP markers associated with yield and yield-related traits in 123 Pakistani historical wheat cultivars evaluated during 2011-2014 seasons under rainfed field conditions. The population was genotyped by using high-density Illumina iSelect 90K single nucleotide polymorphism (SNP) assay, and finally 14,960 high quality SNPs were us...
Loose smut, caused by Ustilago tritici (Pers.) Rostr., is a systemic disease of tetraploid durum wheat (Triticum turgidum L.). Loose smut can be economically controlled by growing resistant varieties, making it important to find and deploy new sources of resistance. Blackbird, a variety of T. turgidum L. subsp. carthlicum (Nevski) A. Love & D. Love, carries a high level of resistance to loose s...
Preharvest sprouting (PHS), the germination of grain on the mother plant under cool and wet conditions, is a recurring problem for wheat farmers worldwide. α-amylase enzyme produced during PHS degrades starch resulting in baked good with poor end-use quality. The Hagberg-Perten Falling Number (FN) test is used to measure this problem in the wheat industry, and determines how much a farmer's whe...
