稻瘟病严重危害水稻产量与品质.水稻抗病遗传基础及分子机制的解析,可为水稻抗病育种提供有效抗性遗传资源和重要的理论指导.本文从水稻稻瘟病抗病基因的克隆、抗性机制解析、产量与稻瘟病抗性的协同调控,以及稻瘟病抗病育种等方面,综述了近年来水稻稻瘟病抗病研究领域的主要进展,并对目前稻瘟病抗病研究中存在的问题进行了讨论与展望.

Rice blast disease, caused by the fungal pathogen Magnaporthe oryzae, poses severe threat to rice yield and quality worldwide. It is important to identify blast resistance genes from rice germplasms and systematically study molecular mechanisms of rice resistance in order to develop effective methods for preventing rice from this disease. Here, we summarize recent advances in the study of rice blast resistance, including isolation of resistance genes, elucidation of the underlying resistance mechanisms, trade-offs between yield and resistance, and breeding of rice varieties with improved disease resistance. We further discuss the challenges in this research field and provide perspectives for future studies.
