摘要
茉莉酸(jasmonic acid,JA)是一种植物内源合成的脂类激素,在植物响应胁迫的调控中发挥着重要作用。本文概括了JA的生物合成与代谢途径及其调控机制;总结了JA信号的传导通路;系统归纳了JA在植物响应生物和非生物胁迫应答中的作用机制和调控网络,重点关注了最新的研究进展。此外,本文梳理了JA与其他植物激素在植物抗逆性调节过程中的信号交流。最后讨论了JA信号通路介导的植物抗逆性研究中亟待解决的问题,并展望了新的分子生物学技术在调控JA信号通路增强作物抗性中的应用前景,以期为植物的抗逆性研究和改良提供参考。
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.
