Metabolic Basis of Pathogenesis and Host Adaptation in Rice Blast

The blast disease, caused by the ascomycete Magnaporthe oryzae , poses a great threat to rice production worldwide. Increasing use of fungicides and or blast-resistant varieties of rice ( Oryza sativa ) has proved to be ineffective in long-term control of blast disease under field conditions. To dev...

Description
Summary:The blast disease, caused by the ascomycete Magnaporthe oryzae , poses a great threat to rice production worldwide. Increasing use of fungicides and or blast-resistant varieties of rice ( Oryza sativa ) has proved to be ineffective in long-term control of blast disease under field conditions. To develop effective and durable resistance to blast, it is important to understand the cellular mechanisms underlying pathogenic development in M. oryzae . In this review, we summarize the latest research in phototropism, autophagy, nutrient and redox signaling, and intrinsic phytohormone mimics in M. oryzae for cellular and metabolic adaptation(s) during its interactions with the host plants.
