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 کاملComparative Analysis of Pathogenicity, Phylogenetic Relationship and Host Fungal Rice Blast Pathogen Magnaporthe grisea
Magnaporthe grisea, also identified as rice blast fungus, rotten rice neck, rice seedling blight, oval leaf spot of graminea, blast of rice [1], pitting disease, ryegrass blast, and Johnson spot is a plant-pathogenic fungus that causes a serious disease affecting rice [2]. Rice blast, caused by Magnaporthe grisea, is considered the most important disease of rice worldwide [3] because of its ext...
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...
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. ...
متن کاملStudy on Differential Response of Pyricularia grisea Isolates from Rice, Finger Millet and Panicum sp. with Local and Alien Media, and Their Host Range
Blast (Pyricularia grisea) is an economically important disease of rice and finger millet in Nepal. Isolates of the fungus from different hosts differed in their response in media for mycelial growth and sporulation. Radial mycelial growth (RMG) and days of sporulation (DOS) of P. grisea were studied by culturing three fungal isolates from rice, finger millet and Panicum sp. on six different me...
