Morphological and Molecular Characterization of Pyricularia Oryzae Causing Blast Disease in Rice (Oryza Sativa) from North India
Rice blast is not only one of the earliest known plant disease but also one of the most widely distributed, occurring in every region of the world where rice is grown. Ten isolates of Pyricularia oryzae causing rice blast disease were evaluated for their morphological, pathogenic, virulence and genetic characterization using RAPD marker. Isolates were classified into three groups based on patho...
متن کاملPyricularia 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 کاملPathogenic Variation and Molecular Characterization of Pyricularia oryzae, Causal Agent of Rice Blast Disease in Tanzania
Rice blast disease, caused by the fungus Pyricularia oryzae, is one of the most devastating diseases of rice. Understanding pathogenic variation and molecular characterization of P. oryzae is one of the most efficient ways to manage the disease. Studies on identification, characterization and pathogenic variation of P. oryzae were conducted in the laboratory and screen-house at Sokoine Universi...
متن کاملPathological Status of Pyricularia angulata Causing Blast and Pitting Disease of Banana in Eastern India
Incidence of leaf blast on nursery plants and pitting disease on maturing banana bunches has been recorded in banana plantations during rainy season in Eastern India during 2014 to 2015. Taxonomical identification as well as DNA sequence analysis of the internal transcribed spacer region of fungus isolated from affected tissue culture derived plantlets and fruits confirmed the pathogen to be Py...
متن کاملInheritance of dsRNAs in the rice blast fungus, Magnaporthe grisea.
The 1.6 and 1.8 kbp dsRNAs have been found in the rice blast fungus, Magnaporthe grisea strain MG01. These dsRNA molecules are located in cytoplasm of the fungal cells and maintained stably during vegetative growth. Three crosses between dsRNA free and dsRNA containing strains including a parental cross, sib-mating and back cross were made to follow the inheritance of dsRNAs during sexual repro...
