Abstract: Rice blast, caused by Magnaporthe oryzae, is one of the most destructive diseases of rice worldwide. The identification and utilization of resistance genes are the basis and key factors for breeding resistance rice cultivars. With the availability of genomic sequences of both Oryza sativa and M. oryzae, rice has become one of the model systems for dissecting the molecular interactions between plants and pathogens. In this paper, we summarize the current status of genetics, mapping, cloning and breeding application of the genes resistant to blast. Using bioinformatics analysis, we analyzed the distribution of all NBS-LRR type of disease resistance genes on the 12 chromosomes of the rice genome and also preliminarily summarized the identified avirulence genes as well as interactions between the resistance proteins and the avirulence proteins. Finally, we analyzed and discussed the problems in rice breeding and prospects for research. This review will provide useful suggestions for further research on rice blast resistance breeding and disease resistance mechanisms.
