The extensive germplasm resource collections that are now available for major crop plants and their wild relatives will increasingly provide valuable biological and bioinformatics resources for plant physiologists and geneticists to dissect the molecular basis of key traits and to develop highly adapted plant material to sustain future breeding programs. A key to the efficient deployment of the...
The importance of wild barley from Qinghai-Tibet Plateau in the origin and domestication of cultivated barley has long been underestimated. Population-based phylogenetic analyses were performed to study the origin and genetic diversity of Chinese domesticated barley, and address the possibility that the Tibetan region in China was an independent center of barley domestication. Wild barley (Hord...
The aim of the present work was to investigate the occurrence of the cell cycle during germination as related to thermodormancy in barley (Hordeum vulgare L., cv. Pewter) grains in relation with abscisic acid (ABA) by: (i) flow cytometry to determine the progression of the cell cycle; and (ii) reverse transcription-PCR to characterize the expression of some important genes involved in cell-cycl...
Assessment of dormancy inception, maintenance and release was studied for artificially dried immature seeds harvested throughout seed development in the barley cv. Triumph and its mutant line TL43. Each was grown in Spain and Scotland under low and high dormancy inducing conditions, respectively. Both TL43 and Triumph followed a similar pattern of release from dormancy across the seasons, altho...
Aflatoxin contamination of peanuts results from invasion and growth of the fungi, Aspergillus flavus and A. parasiticus. Peanut pods develop in the soil where they are in contact with propagules of these ubiquitous fungi. When peanuts are subjected to drought conditions as pods are maturing, they become susceptible to contamination. A method of biological control of aflatoxin contamination was ...
The great majority of seeds from higher plants fail to germinate under anoxic conditions. While the metabolic pathways operating during the aerobic process of seed germination are well described, there is only limited evidence concerning metabolic pathways operating under conditions of limited oxygen availability. This is despite the importance of carbohydrate availability for plant tolerance t...
Barley (Hordeum vulgare L.) is potentially a new source of genes for wheat (Triticum aestivum L.) improvement. Wheat-barley chromosome recombinant lines provide a means for introgressing barley genes to wheat genome by chromosome engineering, and since these are expected to occur only rarely in special cytogenetic stocks, an efficient selection skill is necessary to identify them. To convert RF...
The closely related smut fungi Ustilago maydis, U. hordei, and Sporisorium reilianum f. sp. zeae are facultatively biotrophic basidiomycetes that occur ubiquitously. Teliospores germinate to produce sporidia of different mating type that grow saprophytically and multiply mitotically by budding [1]. For mass proliferation and sexual genetic exchange, successful colonization of economically impor...
Clostridium difficile is an emerging nosocomial pathogen and one of the major causes of antibiotic-associated diarrhoea. Cases of Clostridium difficile-associated disease (CDAD) are likely initiated by the ingestion of dormant C. difficile spores, which then germinate, outgrow and rapidly proliferate to cause gastrointestinal (GI) infections. To understand the initial stages of CDAD pathogenesi...
