摘　　要：植物固定生长不能移动,时刻面临着害虫咬噬、病原微生物侵染等多种外界环境胁迫。为了应对这些胁迫,植物进化出了复杂且被精细调控的防御系统,包括利用植物激素调控抗性基因的表达以及抗性相关次生代谢产物的积累等。有趣的是,许多昆虫和病原微生物被发现能够采用各种策略来逃避、克服甚至操控植物防御系统,以促进其对宿主植物的利用。茉莉素是一种重要的脂质植物激素,调控生长发育的诸多方面,同时也在植物应对多种生物胁迫和非生物胁迫的防御反应中发挥重要作用。近年来,茉莉素的生物合成、信号转导和生理功能等均得到了广泛研究,并取得了一系列重要进展。概述了茉莉素的生物合成调控与信号转导途径,同时也探讨了茉莉素对植物生物胁迫反应的调控机制,并介绍了昆虫和病原微生物对植物茉莉素途径的操控策略,以期为深入理解茉莉素介导的植物与病原生物之间的相互作用提供参考。Being sessile,plants are always challenged by a variety of environmental stresses,including herbivorous insect attack andmicrobial pathogen infection. To defend themselves against these stresses,plants have evolved sophisticated and highly regulated defensesystem,such as activation of biosynthesis of plant hormones that regulate defense-related gene expression and secondary metabolite production.Intriguingly,many herbivorous insects and microbial pathogens have been found to employ distinct strategies to evade,overcome,or evenmanipulate plants＇ defense system to facilitate their exploitation of host plants. Jasmonate,an important class of lipid-derived plant hormone,regulates multiple aspects of plant growth and development and also plays crucial roles in plant responses to diverse biotic and abiotic stresses.In recent years,the biosynthesis,signal transduction and biological functions of jasmonate have been extensively studied,and significantprogresses have been achieved. In this review,we provide a overview of jasmonate biosynthesis regulation and signaling transduction pathway.We also discuss the mechanisms of jasmonate action in plant biotic stress responses and summarize the various strategies used by herbivorousinsects or microbial pathogens to hijack jasmonate pathway. This review would be helpful for an in-depth understanding of jasmonate-mediatedinteractions of plants with pathogenic organisms.
