Abstract  Rice blast disease, caused by Magnaporthe oryzae, threatens global food security.  The rice blast pathosystem is a longstanding model system for understanding plant-microbe interactions.  In order to elucidate the coevolution of the host and pathogen, and provide the appropriate methods for preventing or controlling rice blast disease, researchers have focused on the evolution of virulence factors and resistance genes.  Thus far, more than 30 rice blast resistance (R) genes and 12 avirulence (Avr) genes have been cloned.  This review summarizes the cloned rice blast R genes, cloned Avr genes of M. oryzae and the interaction between them.  This discussion also considers some of the major unanswered questions concerning this pathosystem and the opportunities for future investigations.
