氧脂素12-氧代-植物二烯酸（OPDA）是一种重要的植物激素茉莉酸的生物合成前体。然而，OPDA也是一种信号分子，其功能不依赖于茉莉酸酯。OPDA参与不同的生物过程，从植物防御和胁迫反应到生长调节和发育，已经在植物物种中被记录。OPDA在质体中由α-亚麻酸合成，并且OPDA与质体亲环蛋白的结合激活与应激反应相关的基因上游的TGA转录因子。在这里，我们总结了什么是已知的OPDA代谢和信号，同时简要讨论其茉莉酸依赖和独立的作用。我们还描述了开放的问题，如OPDA蛋白质相互作用组和OPDA缀合物的生物学作用。
The oxylipin 12-oxo-phytodienoic acid (OPDA) is known as a biosynthetic precursor of the important plant hormone jasmonic acid. However, OPDA is also a signaling molecule with functions independent of jasmonates. OPDA involvement in diverse biological processes, from plant defense and stress responses to growth regulation and development, has been documented across plant species. OPDA is synthesized in the plastids from alpha-linolenic acid, and OPDA binding to plastidial cyclophilins activates TGA transcription factors upstream of genes associated with stress responses. Here, we summarize what is known about OPDA metabolism and signaling while briefly discussing its jasmonate dependent and independent roles. We also describe open questions, such as the OPDA protein interactome and biological roles of OPDA conjugates.
