title: The Role of Cell Wall Degrading Enzymes in Pathogenesis of Magnaporthe oryzae.
abstract: The plant cell wall is always the physical barrier in which phytopathogenic fungi must overcome by producing an array of cell wall degrading enzymes (CWDEs) that allow them to invade host tissues through the degradation of cell wall components of plants. Magnaporthe oryzae is a causal agent of blast disease, one of the most devastating disease in rice resulting significant crop losses worldwide. The penetration of plant cuticle and cell walls induced by infection structures of M. oryzae has been known to be acquired by the association of turgor pressure and CWDEs for successful infection of M. oryzae. In this review, we focus on recent discoveries of M. oryzae CWDEs, gene regulation and their biological roles as fungal virulence factors and elicitors of host defense response leading to plant resistance against fungal pathogens.
