Salicylic acid (SA) is a natural potent signaling molecule, synthesized from the amino acid phenylalanine or chorismate, involved in induction of plant defense strategies associated with stress conditions. The significance of salicylic acid (SA) has been increasingly recognized in improved plant abiotic stress-tolerance via SA-mediated control of major plant metabolic processes such as photosynthesis, metabolite accumulation, redox homeostasis and gene regulation. Nonetheless, extensive genomic and proteomic studies are expected to broadly reveal SA-responsive pathways regulating genes and proteins upon stresses. Based on recent observations, the review focuses on metabolism of SA and interaction with major signaling molecules and phytohormones, thus unraveling the mechanism of SA mediated abiotic stress tolerance.

水杨酸 (SA) 是一种天然有效的信号分子，由氨基酸苯丙氨酸或分支酸合成，参与诱导与胁迫条件相关的植物防御策略。水杨酸 (SA) 通过 SA 介导的对主要植物代谢过程（如光合作用、代谢物积累、氧化还原稳态和基因调控）的控制在提高植物非生物胁迫耐受性方面的重要性日益得到认可。尽管如此，广泛的基因组和蛋白质组学研究有望广泛揭示在压力下调节基因和蛋白质的 SA 反应途径。根据最近的观察，该综述着重于 SA 的代谢以及与主要信号分子和植物激素的相互作用，从而揭示了 SA 介导的非生物胁迫耐受机制。
