| Abstract: | Rice blast, caused by fungus Pyricularia oryzae, is one of the most serious fungal diseases, which threatens rice production. Cloning and identification of rice blast resistance genes, systematically and in-depth analysis of the interaction between P. oryzae and rice could reveal the rice disease resistance mechanisms and develop numerous new rice germplasm. These efforts are effective and provide safeguard for food security. In this article, we reviewed the identification of rice blast resistance and susceptibility genes to P. oryzae in the past 10 years, and how the knowledge of the molecular mechanisms has been applied in rice breeding. In addition, we summarized major strategies for breeding rice disease-resistant cultivars including disease resistance gene pyramiding, molecular design breeding, editing of susceptibility genes and pathogen-induced expression of disease resistance genes. Lastly, we proposed directions and challenges in rice blast disease resistance breeding in the future: full utilization of germplasm resources, application of new technologies to mine new resistance genes and create new breeding materials; investigation of the molecular basis of leaf and neck blast resistance and construction of novel broad-spectrum disease-resistant materials. |
