Abstract：
Jasmonic acid (JA), a plant endogenously synthesized lipid hormone, plays an important role in response to stress. This manuscript summarized the biosynthesis and metabolism of JA and its related regulatory mechanisms, as well as the signal transduction of JA. The mechanism and regulatory network of JA in plant response to biotic and abiotic stresses were systematically reviewed, with the latest advances highlighted. In addition, this review summarized the signal crosstalk between JA and other hormones in regulating plant resistance to various stresses. Finally, the problems to be solved in the study of plant stress resistance mediated by JA were discussed, and the application of new molecular biological technologies in regulating JA signaling to enhance crop resistance was prospected, with the aim to facilitate future research and application of plant stress resistance.
摘要：
茉莉酸（JA），一种植物内源性合成的脂类激素，在应激反应中起着重要作用。本文综述了JA的生物合成和代谢及其相关调控机制,以及JA的信号转导。系统综述了JA在植物响应生物和非生物胁迫中的作用机制和调控网络。强调了最新的进展。此外,本文综述了JA与其他激素在调节植物对各种胁迫的抗性中的信号串扰。最后,讨论了JA介导的植物抗逆性研究中需要解决的问题，展望了分子生物学新技术在调控JA信号增强作物抗逆性方面的应用,目的是促进未来植物抗逆性的研究和应用。
