The phytohormone abscisic acid (ABA) is the best‐known stress signaling molecule in plants. ABA protects sessile land plants from biotic and abiotic stresses. The conserved pyrabactin resistance/pyrabactin resistance‐like/regulatory component of ABA receptors (PYR/PYL/RCAR) perceives ABA and triggers a cascade of signaling events. A thorough knowledge of the sequential steps of ABA signaling will be necessary for the development of chemicals that control plant stress responses. The core components of the ABA signaling pathway have been identified with adequate characterization. The information available concerning ABA biosynthesis, transport, perception, and metabolism has enabled detailed functional studies on how the protective ability of ABA in plants might be modified to increase plant resistance to stress. Some of the significant contributions to chemical manipulation include ABA biosynthesis inhibitors, and ABA receptor agonists and antagonists. Chemical manipulation of key control points in ABA signaling is important for abiotic and biotic stress management in agriculture. However, a comprehensive review of the current knowledge of chemical manipulation of ABA signaling is lacking. Here, a thorough analysis of recent reports on small‐molecule modulation of ABA signaling is provided. The challenges and prospects in the chemical manipulation of ABA signaling for the development of ABA‐based agrochemicals are also discussed.

脱落酸信号的化学操作：农业非生物和生物胁迫管理的新方法

植物激素脱落酸（ABA）是植物中最著名的应激信号分子。ABA 保护固着的陆地植物免受生物和非生物胁迫。ABA 受体 (PYR/PYL/RCAR) 的保守的吡拉巴汀抗性/吡拉巴汀抗性样/调节成分感知 ABA 并触发一系列信号事件。全面了解 ABA 信号传导的连续步骤对于开发控制植物胁迫反应的化学物质是必要的。ABA 信号通路的核心成分已被鉴定并具有充分的特征。关于 ABA 生物合成、运输、感知和代谢的现有信息使得人们能够对如何改变植物中 ABA 的保护能力以提高植物对胁迫的抵抗力进行详细的功能研究。对化学操作的一些重要贡献包括 ABA 生物合成抑制剂、ABA 受体激动剂和拮抗剂。ABA 信号传导关键控制点的化学操作对于农业中的非生物和生物胁迫管理非常重要。然而，目前缺乏对 ABA 信号化学操作知识的全面回顾。本文对最近有关 ABA 信号传导小分子调节的报告进行了全面分析。还讨论了 ABA 信号化学调控对于开发基于 ABA 的农用化学品的挑战和前景。
