摘　要：

在自然界中，植物持续应对病原菌的挑战，演化出了一套精细的免疫系统以抵御这些威胁。植物激素调控网络是这一防御体系中的核心组成部分，其中茉莉酸(jasmonic acid, JA) 在植物与病原菌的相互作用中扮演着复杂且多面的角色。本文深入分析了茉莉酸的生物合成及代谢，揭示了其信号转导途径，并探讨了其在植物与多种病原菌互作中的关键作用和功能多样性。本文重点讨论了茉莉酸途径在植物免疫信号转导中的作用机制，并对其在农业实践中的应用潜力进行了展望，旨在为抗病作物培育提供科学依据和策略指导。

Abstract:

In nature, plants continuously face the challenge of pathogens and have evolved a sophisticated immune  system to cope with these threats. The phytohormone regulatory network represents a central component of this defense system, in which jasmonic acid (JA) plays a complex and multifaceted role in plant-pathogen interactions. This review presents a comprehensive analysis of jasmonic acid biosynthesis and metabolism, elucidates its signal transduction pathways, and emphasizes its pivotal roles and functional diversity in plant interactions with different pathogens. It focuses on the mechanism of the jasmonic acid pathway in plant immunity and discusses the potential application in agricultural practice, aiming to provide scientific   foundations and strategic guidance for the breeding of disease-resistant crops.
