A fungal metallothionein is required for pathogenicity of Magnaporthe grisea.
The causal agent of rice blast disease, the ascomycete fungus Magnaporthe grisea, infects rice (Oryza sativa) plants by means of specialized infection structures called appressoria, which are formed on the leaf surface and mechanically rupture the cuticle. We have identified a gene, Magnaporthe metallothionein 1 (MMT1), which is highly expressed throughout growth and development by M. grisea an...
متن کاملSystematic characterization of the peroxidase gene family provides new insights into fungal pathogenicity in Magnaporthe oryzae
Fungal pathogens have evolved antioxidant defense against reactive oxygen species produced as a part of host innate immunity. Recent studies proposed peroxidases as components of antioxidant defense system. However, the role of fungal peroxidases during interaction with host plants has not been explored at the genomic level. Here, we systematically identified peroxidase genes and analyzed their...
متن کاملThe PEX7-Mediated Peroxisomal Import System Is Required for Fungal Development and Pathogenicity in Magnaporthe oryzae
In eukaryotes, microbodies called peroxisomes play important roles in cellular activities during the life cycle. Previous studies indicate that peroxisomal functions are important for plant infection in many phytopathogenic fungi, but detailed relationships between fungal pathogenicity and peroxisomal function still remain unclear. Here we report the importance of peroxisomal protein import thr...
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 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...
