Pyricularia graminis-tritici, a new Pyricularia species causing wheat blast
Pyricularia oryzae is a species complex that causes blast disease on more than 50 species of poaceous plants. Pyricularia oryzae has a worldwide distribution as a rice pathogen and in the last 30 years emerged as an important wheat pathogen in southern Brazil. We conducted phylogenetic analyses using 10 housekeeping loci for 128 isolates of P. oryzae sampled from sympatric populations of wheat,...
متن کاملEvaluation of Pearl Millet Grain Hybrids for Resistance to Meloidogyne spp. and Leaf Blight Caused by Pyricularia grisea
Pearl millet, Pennisetum glaucum, has potential as a grain crop in the southeastern United States. Although it is used as a food grain in India and Africa, its primary use in the United States is high quality feed for poultry and livestock (1,6,15). Hybrids adapted to the southeast should be high yielding, resistant to the rust fungus Puccinia substriata var. indica, and early maturing. The two...
متن کاملCharacterization of a Pyricularia grisea population from Uruguay by molecular analysis.
Blast disease, caused by hemibiotrophic fungus Pyricularia oryzae Sacc. (teleomorph: Magnaporthe oryzae (Hebert) Barr.), previously known as Magnaporthe grisea, is the most serious disease of rice and causes high yield losses in most rice growing regions every year. Blast is an endemic disease in all Iranian and Uruguayan rice fields, with yield losses up to 90 % that has been reported from som...
متن کاملDesign and Development of Early Warning System for Desertification and Land Degradation
Early warning systems are key components of strategies to reduce risk. This research, by adopting a systematic approach in the management of the risk of desertification and by including previously developed models and systems, offers an integrated efficient structure in terms of early warning for the risk of desertification as a pilot system for semi-arid areas of west Golestan Province in IRAN...
متن کاملA hybrid machine model of rice blast fungus, Magnaporthe grisea.
The fungus, Magnaporthe grisea (Rice blast fungus) is a major agricultural problem affecting rice and related food crops. The way that the fungus invades the host plant and propagates itself is a very important scientific problem and recent advances in research into the genetic basis of these processes can be used to build a simple partial model using hybrid computational modelling techniques. ...
