关键信息本文对控制稻飞虱相互作用的遗传和生化机制进行了全面综述，旨在为稻飞虱的有效控制和促进水稻抗稻飞虱的育种做出贡献。 摘要 稻飞虱是水稻最具破坏性的害虫，对水稻生产构成重大威胁。褐飞虱(BPH)、白背飞虱(WBPH)和小褐飞虱(SBPH)是飞虱属的三种，是水稻重要的刺吸式害虫。寄主植物抗性已被认为是控制飞虱的最实用、经济和环境友好的策略。迄今为止，已分别鉴定出至少 30、14 和 34 个抗 BPH、WBPH 和 SBPH 的主要基因/数量性状位点。最近的基因遗传和分子图谱分析表明，水稻中一些来自不同供体的抗飞虱基因聚集成簇，而单个供体对这三种飞虱的抗性不是由任何一个显性基因控制，而是由多个基因控制。值得注意的是，Bph14、Bph26、Bph3和Bph29被成功鉴定为水稻褐飞虱抗性基因。对飞虱取食的生物和化学研究表明，水稻植物已经获得了多种形式的针对飞虱的防御能力。在水稻与飞虱的相互作用中，水稻通过激活水杨酸依赖性系统获得性抗性而非茉莉酸依赖性激素反应途径来防御飞虱。抗飞虱机制的转基因水稻表明，茉莉酸及其代谢产物在水稻抗飞虱方面发挥着多种作用。了解水稻抗性的遗传和生化机制将有助于对此类害虫进行实质性控制，并促进水稻更有效地抗飞虱育种。
Key messageThis article presents a comprehensive review on the genetic and biochemical mechanisms governing rice-planthopper interactions, aiming to contribute substantial planthopper control and facilitate breeding for resistance to planthoppers in rice.AbstractThe rice planthopper is the most destructive pest of rice and a substantial threat to rice production. The brown planthopper (BPH), white-backed planthopper (WBPH) and small brown planthopper (SBPH) are three species of delphacid planthoppers and important piercing-sucking pests of rice. Host-plant resistance has been recognized as the most practical, economical and environmentally friendly strategy to control planthoppers. Until now, at least 30, 14 and 34 major genes/quantitative trait loci for resistance to BPH, WBPH and SBPH have been identified, respectively. Recent inheritance and molecular mapping of gene analysis showed that some planthopper-resistance genes in rice derived from different donors aggregate in clusters, while resistance to these three species of planthoppers in a single donor is governed not by any one dominant gene but by multiple genes. Notably,Bph14,Bph26,Bph3andBph29were successfully identified as BPH-resistance genes in rice. Biological and chemical studies on the feeding of planthoppers indicate that rice plants have acquired various forms of defence against planthoppers. Between the rice-planthopper interactions, rice plants defend against planthoppers through activation the salicylic acid-dependent systemic acquired resistance but not jasmonate-dependent hormone response pathways. Transgenic rice for the planthopper-resistance mechanism shows that jasmonate and its metabolites function diversely in rice’s resistance to planthopper. Understanding the genetic and biochemical mechanisms underlying resistance in rice will contribute to the substantial control of such pests and facilitate breeding for rice’s resistance to planthopper more efficiently.
