Salicylic acid (SA) has emerged as a key plant defense hormone with critical roles in different aspects of plant immunity. Analysis of Arabidopsis mutants revealed complex regulation of pathogen-induced SA biosynthesis. Studies on SA-insensitive mutants led to the identification of the SA receptors and how SA regulates defense gene expression. Consistent with its critical roles in plant immunity, SA is required for the assembly of a normal root microbiome and various pathogen effectors have evolved to target components of SA biosynthesis or signaling. This review discusses recent advances in SA biology, focusing in particular on the regulation of SA biosynthesis and SA perception.
水杨酸（SA）作为一种关键的植物防御激素，在植物免疫的不同方面都起着至关重要的作用。拟南芥突变体的分析揭示了病原菌诱导的 SA 生物合成的复杂调控。对 SA 不敏感突变体的研究导致了 SA 受体的鉴定以及 SA 如何调节防御基因表达。与它在植物免疫中的关键作用一致，SA 是组装正常根微生物组所必需的，各种病原体效应物已经进化到针对 SA 生物合成或信号传导的成分。这篇综述讨论了 SA 生物学的最新进展，特别关注 SA 生物合成和 SA 感知的调控。
