Salicylic acid (SA) and jasmonic acid (JA) are the two most important phytohormones in plant immunity. While SA plays pivotal roles in local and systemic acquired resistance (SAR) against biotrophic pathogens, JA, on the other hand, contributes to defense against necrotrophic pathogens, herbivores, and induced systemic resistance (ISR). Over the past 30 years, extensive research has elucidated the biosynthesis, metabolism, physiological functions, and signaling of both SA and JA. Here, we present an overview of signaling pathways of SA and JA and how they interact with each other to fine-tune plant defense responses.
水杨酸（SA）和茉莉酸（JA）是植物免疫中两个最重要的植物激素。SA在针对活体营养型病原体的局部和系统获得性抗性（SAR）中起关键作用，而JA则有助于抵御坏死营养型病原体、食草动物以及诱导系统抗性（ISR）。在过去30年里，广泛的研究已经阐明了SA和JA的生物合成、代谢、生理功能及信号传导。在此，我们概述SA和JA的信号通路，以及它们如何相互作用以微调植物防御反应。
