Genetic dissection of grain weight in bread wheat was undertaken through both genome-wide quantitative trait locus (QTL) interval mapping and association mapping. QTL interval mapping involved preparation of a framework linkage map consisting of 294 loci {194 simple sequence repeats (SSRs), 86 amplified fragment length polymorphisms (AFLPs) and 14 selective(More)
Association mapping was undertaken in common wheat to identify markers associated with pre-harvest sprouting tolerance (PHST). For this purpose, a population of 242 wheat genotypes and 250 SSR markers were used. The population used consisted of diverse germplasm, which carried sufficient phenotypic variation for PHS for conducting association mapping. The(More)
Genetic diversity was examined in a collection of 263 Indian bread wheat (Triticum aestivum L.) cultivars using 90 SSR markers. These cultivars were classified into Group I (pre-green revolution cultivars) and Group II cultivars (post-green revolution cultivars). SSR markers were also classified into Set-I SSRs (42 random genomic SSRs) and Set-II SSRs (48(More)
Common wheat (Triticum aestivum L.) contributes substantially to global food and nutritional security. Thus, an important goal of wheat breeding is to develop high-yielding varieties with better nutritional quality and resistance to all major diseases. During the present study, in the background of a popular elite wheat cultivar PBW343, we pyramided eight(More)
Common wheat is unique in providing a large number of diverse end-products, including chapati, biscuits, bread and noodles. Grain weight and other grain traits contribute to grain yield and milling quality. Many earlier QTL studies reported at least 332 QTLs for grain traits including grain weight. We conducted a QTL analysis (composite interval mapping) of(More)
We report the first complete microsatellite genetic map of jute (Corchorus olitorius L.; 2n = 2 × = 14) using an F6 recombinant inbred population. Of the 403 microsatellite markers screened, 82 were mapped on the seven linkage groups (LGs) that covered a total genetic distance of 799.9 cM, with an average marker interval of 10.7 cM. LG5 had the longest and(More)
Molecular markers are useful for a variety of purposes relevant to crop improvement. The most important of these uses is the indirect marker-assisted selection (MAS) exercised during plant breeding. For this purpose, molecular markers need to be amenable to automation and high throughput approaches. However, the gel-based assays that are needed for most(More)
Wheat (Triticum aestivum L.), with a large genome (16000 Mb) and high proportion ( approximately 80%) of repetitive sequences, has been a difficult crop for genomics research. However, the availability of extensive cytogenetics stocks has been an asset, which facilitated significant progress in wheat genomic research in recent years. For instance, fairly(More)
The United States lung cancer epidemic has not yet been controlled by present prevention and treatment strategies. Overexpression of a Mr 31,000 protein, heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1, had shown promise as a marker of lung cancer. In a pilot study of archived preneoplastic sputum specimens, hnRNP A2/B1 overexpression more accurately(More)
BACKGROUND AND AIMS Middle ear surgery requires bloodless surgical field for better operating conditions, deep level of anaesthesia and rapid emergence. Recent studies suggest that α2 agonists could provide desired surgical field, sedation and analgesia. The present study was aimed to evaluate the clinical effects of dexmedetomidine infusion as anaesthetic(More)
