Comparative 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 کاملComparative Analysis of Pathogenicity and Phylogenetic Relationship in Magnaporthe grisea Species Complex
Outbreaks of rice blast have been a threat to the global production of rice. Members of the Magnaporthe grisea species complex cause blast disease on a wide range of gramineous hosts, including cultivated rice and other grass species. Recently, based on phylogenetic analyses and mating tests, isolates from crabgrass were separated from the species complex and named M. grisea. Then other isolate...
متن کاملRac1 Is Required for Pathogenicity and Chm1-Dependent Conidiogenesis in Rice Fungal Pathogen Magnaporthe grisea
Rac1 is a small GTPase involved in actin cytoskeleton organization and polarized cell growth in many organisms. In this study, we investigate the biological function of MgRac1, a Rac1 homolog in Magnaporthe grisea. The MgRac1 deletion mutants are defective in conidial production. Among the few conidia generated, they are malformed and defective in appressorial formation and consequently lose pa...

متن کاملRegulatory Genes Controlling MPG1 Expression and Pathogenicity in the Rice Blast Fungus Magnaporthe grisea.
MPG1, a pathogenicity gene of the rice blast fungus Magnaporthe grisea, is expressed during pathogenesis and in axenic culture during nitrogen or glucose limitation. We initiated a search for regulatory mutations that would impair nitrogen metabolism, MPG1 gene expression, and pathogenicity. First, we developed a pair of laboratory strains that were highly fertile and pathogenic toward barley. ...
