摘要(Abstract)：

粮食安全问题一直是全球热点问题。作为全球一半以上人口的主食，水稻(Oryza sativa L.)的产量和品质对保障全球粮食安全具有重要意义，而病害是影响水稻产量最大的不稳定因素之一。稻叶素(Oryzalexin)是一类水稻中独有的具有抗菌作用的植保素，是水稻自身抵御病菌侵害的重要防御物质。它能够通过影响病原菌结构的稳定性及抑制其孢子萌发和菌丝伸长等繁殖行为防御病原菌，但目前对于稻叶素合成机制、信号介导路径及抗菌机制缺乏整体认识。因此，本文系统地总结了Oryzalexin的化学结构与生物合成过程、抗菌机制及其应用手段的研究进展，并针对Oryzalexin未来的相关研究进行了展望，为深入了解利用Oryzalexin防治病原菌提供了理论参考。
