Using an empirical panel of more than 20 000 single base primer extension (SNP-IT) assays we have developed a set of statistical scores for evaluating and rank ordering various parameters of the SNP-IT reaction to facilitate high-throughput assay primer design with improved likelihood of success. Each score predicts either signal magnitude from primer extension or signal noise caused by misprim...
Tomato spotted wilt virus (TSWV) is one of the most destructive viral diseases that threaten worldwide tomato (Solanuum lycopersicum L. syn Lycopersicon esculentum Mill.) production. Use of host resistance appears to be the best way to control the disease. Marker assisted selection (MAS) has become very important and useful in the selection of TSWV resistance genes. The objective of this resear...
63 Bean rust is a devastating disease of common bean in the Americas and Africa. The historically 64 important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen 65 that overcome all known rust resistance genes. Existing molecular markers tagging Ur-3 for use 66 in marker assisted selection produce false results. We described here the fine mapping of Ur-3 67 fo...
The potential of different DNA based molecular markers was examined for the detection of single nucleotide polymorphism (SNP) in the waxy gene and a microsatellite (SSR) sequence closely linked to it in a collection of rice varieties. DNA was extracted from leaf samples of 68 different rice cultivars by the CTAB method and specific primers were designed for the amplification of waxy gene and SS...
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. ...
Soybean oil content is one of main quality traits. In this study, we used the multifactor dimensionality reduction (MDR) method and a soybean high-density genetic map including 5,308 markers to identify stable single nucleotide polymorphism (SNP)-SNP interactions controlling oil content in soybean across 23 environments. In total, 36,442,756 SNP-SNP interaction pairs were detected, 1865 of all ...
In order to identify loci controlling seedling morpho-physiologic characteristics in 88 bread wheat cultivars, a greenhouse experiment based on simple alpha lattice was conducted under both normal and 120 mM (12 ds/m) salt stress condition of the Faculty of Agriculture, Urmia University in 2020-2021 cropping season. Chlorophyll a, b and carotenoid content, proline, plant fresh and dry weight, p...
Cucumber is a widely grown vegetable crop plant and host to many different pathogens. vein yellowing virus (CVYV) causes economic losses on cucumber crops in Mediterranean countries some part of India such as West Bengal African Sudan. CVYV an RNA potyvirus transmitted mechanically by whitefly ( Bemisia tabaci ) semipersistent manner. Control this heavily dependent the management insect vector ...
Background Tree breeding is logistically complex and expensive, and breeders have long sought to use molecular markers to accelerate breeding. A candidate gene approach based on testing for association between the presence of DNA sequence variation in or near candidate genes, and phenotypic variation in a population has long been explored [1,2]. However, using candidate gene approach (QTLs) has...
In genomic prediction, common analysis methods rely on a linear mixed-model framework to estimate SNP marker effects and breeding values of animals or plants. Ridge regression–best linear unbiased prediction (RR-BLUP) is based on the assumptions that SNP marker effects are normally distributed, are uncorrelated, and have equal variances. We propose DAIRRy-BLUP, a parallel, Distributed-memory RR...
