Abstract
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）是植物免疫中最重要的两种植物激素。水杨酸在对抗生物营养型病原体的局部和系统获得性抗性（SAR）中发挥关键作用。而 JA 则有助于抵御坏死性病原体、食草动物和诱导性系统抗性（ISR）。在过去的 30 年中，大量研究阐明了 SA 和 JA 的生物合成、代谢、生理功能和信号传递。在此，我们将概述 SA 和 JA 的信号通路，以及它们如何相互影响以微调植物的防御反应。
