Alternaria solani Sorauer (Ellis), a foliar pathogen of potato (Solanum tuberosum L.), was considered to be difficult to control, responsible for yield losses of up to 30% (24), until the registration of the first strobilurin fungicide, azoxystrobin (Quadris; Syngenta Crop Protection, Greensboro, NC), in 1999. Strobilurins belong to the group of chemicals classified as Quinone outside inhibitor...
The order Magnaporthales comprises about 200 species and includes the economically and scientifically important rice blast fungus and the take-all pathogen of cereals, as well as saprotrophs and endophytes. Recent advances in phylogenetic analyses of these fungi resulted in taxonomic revisions. In this paper we list the 28 currently accepted genera in Magnaporthales with their type species and ...
AIMS Isolation of bacterial antagonist for use in the biological control of phytopathogenic fungi like rice blast fungus, Magnaporthe grisea, and to further purify and characterize the antifungal molecule produced by the antagonist. METHODS AND RESULTS Bacterial antagonist exhibiting highest antifungal activity against the rice blast fungus M. grisea was isolated from soil and identified as B...
We have identified a family of dispersed repetitive DNA sequences in the genome of Magnaporthe grisea, the fungus that causes rice blast disease. We have named this family of DNA sequences "MGR" for M. grisea repeat. Analysis of five MGR clones demonstrates that MGR sequences are highly polymorphic. The segregation of MGR sequences in genetic crosses and hybridization of MGR probes to separated...
بیماری بلاست (Pyricularia grisea Sacc) تهدید جدی برای تولید برنج میباشد. تعداد هشت ژنوتیپ برنج به همراه دو رقم نعمت (شاهد مقاوم) و بینام (شاهد حساس) برای مقاومت به بیماری بلاست در سال 1390 مورد ارزیابی قرار گرفتند. آزمایش تحت شرایط مزرعه و گلخانه انجام گرفت. نتایج آزمایش مزرعهای بر اساس صفات تیپ آلودگی، شدت بلاست خوشه، پیشرفت بیماری بلاست برگی و خوشه نشان داد که ژنوتیپهای B40، بینام و IRBL...
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...
