The aim of this study was to investigate methods for detecting QTL in outbred commercial pig populations. Several QTL for back fat and growth rate, previously detected in experimental resource populations, were examined for segregation in 10 different populations. Two hundred trait-by-population-by-chromosome tests were performed, resulting in 20 tests being significant at the 5% level. In addi...
Over the last few decades, the use of molecular markers has played an increasing role in rice breeding and genetics. Of the different types of molecular markers, microsatellites have been utilized most extensively, because they can be readily amplified by PCR and the large amount of allelic variation at each locus. Microsatellites are also known as simple sequence repeats (SSR), and they are ty...
In our early experiments, the chloroform extract of D. crassirhizoma was demonstrated to contain the highest concentrations of total phloroglucinols among several extract fractions and possessed the most effective nematicidal activity. This study aimed to ascertain the ultrastructural changes in M. incognita after treatment with a D. crassirhizoma chloroform extract at 1 mg·mL⁻¹ for 24 h. It wa...
Disease resistance gene pyramiding is a widely used strategy to enhance durability. Marker-assisted selection (MAS) was applied pyramide the alleles Run1 and Ren3, which confer against grape powdery mildew (Erysiphe necator). Two F1 full-sibs carrying Ren3 in heterozygosity were selfed develop breeding populations analysis. From 637 genotyped plants, 313 (50.6%) had pyramided. Seven (1.1%) of t...
Gene identification is the process of identifying genomic DNA regions that encode proteins. It has a wide range applications in structural genomics, functional metabolomics, transcriptomics, proteomics, and other genetic-related studies such as genetic disorder detection, treatment prevention. There are several methods for finding genes, including ab-initio method (intrinsic) sequence similarit...

We have observed 1H NMR spectra of hydrogen molecules trapped inside modified fullerene cages under cryogenic conditions. Experiments on static samples were performed at sample temperatures down to 4.3 K, while magic-angle-spinning (MAS) experiments were performed at temperatures down to 20 K at spinning frequencies of 15 kHz. Both types of NMR spectra show a large increase in the intramolecula...
نشانگرهای مولکولی ابزار ارزشمندی برای به نژادی گیاهان و به ویژه شناسایی ژرم پلاسم و انتخاب غیرمستقیم هستند. انتخاب به کمک نشانگر (Marker-Asisted Selection: MAS) برای مقاومت به آفات و بیماری ها و صفات مرتبط با کیفیت برخی گیاهان زراعی به عنوان بارزترین مثال به کارگیری روتین MAS در طرح های به نژادی مطرح است. با این حال کاربرد عملی نشانگر مولکولی معلوم کرده است که موفقیت در MAS به عواملی از جمله اس...
Introduction: Diabetic retinopathy (DR) is the single largest cause of sight loss and blindness in the working age population of Western countries; it is the most common cause of blindness in adults between 20 and 60 years of age. Early diagnosis of DR is critical for preventing vision loss so early detection of microaneurysms (MAs) as the first signs of DR is important. This paper addresses th...
