Abstract

Rice blast disease, caused by Magnaporthe oryzae, threatens global food security. Owning to the rapid evolution of M. oryzae isolates, resistant cultivars always become susceptible in 3-5 years. Breeding and planting durable resistant cultivars is the most effective method. Recent advances in understanding the pathogenesis of M. oryzae and rice resistance mechanisms led to a deeper understanding of PAMPs- and effector- triggered immunity in this pathosystem. This review summarizes the recent progresses for PTI, the cloned rice blast R genes, cloned Avr genes of M. oryzae and the interaction between them. We also discussed some of the major unanswered questions for this pathosystem and the opportunities for future investigations.
