Abstract:

Jasmonic acid (JA), acting as an important new endogenous hormone, fulfills the diversity of roles in plant defense against pathogens and insects. In recent years, more and more studies have shown that JA also plays an important role in plant development and osmotic stress. To advance our understanding of these novel functions of JA, this paper described how the key regulators of JA signaling pathway regulate photosynthesis and the development of root and stomata in plants in this review. The progress was expected to provide some new insights for us to understand the crosstalk between JA signaling and plant development and osmotic stress.

Key words:  jasmonic acid, signal transduction, stress resistance

摘要：

茉莉酸（jasmonic acid,JA）作为一种重要的新型植物内源激素广泛参与调控植物防御反应和形态发育相关的多种生物学过程。近年来，越来越多的研究发现茉莉酸在调控植物发育和渗透胁迫应答等方面发挥着重要作用。从茉莉酸信号传导途径中的关键节点基因对根、气孔的发育以及对光合作用的影响阐述了该信号途径在植物抗逆性方面的最新研究进展，从而为全面认识茉莉酸及其信号途径在植物抗旱、耐盐碱方面所发挥的作用提供参考。
