Salicylic acid (SA) is a phytohormone that plays a critical role in plant growth, development, and response to unfavorable conditions. Over the past three decades, researches on SA have deeply elucidated the mechanism of its function in plants tolerance to infection by biotrophic and hemibiotrophic pathogens. Recent studies have found that SA also plays an important role in regulating plants response to abiotic stress. It is emerging as a strong tool for alleviating adverse effects of biotic and abiotic stresses in crop plants. During SA-mediated stress responses, many small molecules participate in the SA modification or signaling, which play important regulatory roles. The cooperations of small molecules in SA pathway remain least discussed, especially in terms of SA-induced abiotic stress tolerance. This review provides an overview of the recent studies about SA and its relationship with different small molecules and highlights the critical functions of small molecules in SA-mediated plant stress responses.
水杨酸（SA）是一种植物激素，在植物生长、发育以及对不利条件的响应中发挥着关键作用。在过去三十年里，对SA的研究已深入阐明了其在植物耐受活体营养型和半活体营养型病原体感染方面的功能机制。最近的研究发现，SA在调节植物对非生物胁迫的响应中也起着重要作用。它正成为减轻作物中生物和非生物胁迫不利影响的有力工具。在SA介导的胁迫反应过程中，许多小分子参与SA修饰或信号传导，发挥着重要的调节作用。SA途径中小分子之间的协同作用仍鲜少被讨论，尤其是在SA诱导的非生物胁迫耐受性方面。本综述概述了关于SA及其与不同小分子关系的最新研究，并强调了小分子在SA介导的植物胁迫反应中的关键功能。
