水稻抗病分子机制研究进展

Recent Progress in Molecular Mechanism of Rice Disease Resistance

水稻作为重要粮食作物之一,是全球一半以上人口的主粮。水稻高产、稳产与国民经济发展密切相关,然而,水稻生产上的各种病虫害是其稳产与增产的严重威胁。培育与种植水稻病害高抗品种是目前最为经济有效、安全健康与环境友好的水稻病害育种策略,而对水稻抗病分子机制的深入研究,可为培育水稻病害高抗品种提供重要理论基础。在过去20年间,科学家们在水稻抗病分子机制方面取得了许多重要进展,综述了水稻免疫防御系统识别病原菌及其信号传导机制等方面的研究进展,以及这些研究进展在水稻抗病育种中的应用,并讨论与展望了水稻抗病分子机制研究领域所面临的挑战与发展方向。

Rice as one of the most important crop which is the staple food for more than half of the population in the world. Maintaining high and stable rice yield are closely related to the national economic development. However,various plant diseases and insect pests pose to seriously yield production lost threat on rice. Breeding and plant high disease resistance cultivar is the most economic effective,safe,healthy and environment friendly rice disease breeding strategy,and in-depth studies in rice disease resistance molecular mechanism can provide important theoretical basis for cultivation of high disease resistance rice varieties. In the past two decades,scientists have made important progress in the molecular mechanism of rice disease resistance. This review summarizes the recent progress towards understanding the recognition and signaling events that govern rice innate immunity and the application in rice disease resistance breeding. We also discuss and prospect the challenges and future directions for research that will further our understanding of rice disease resistance.
