Tea plants have to adapt to frequently challenging environments due to their sessile lifestyle and perennial evergreen nature. Jasmonates regulate not only tea plants' responses to biotic stresses, including herbivore attack and pathogen infection, but also tolerance to abiotic stresses, such as extreme weather conditions and osmotic stress. In this review, we summarize recent progress about jasmonaic acid (JA) biosynthesis and signaling pathways, as well as the underlying mechanisms mediated by jasmontes in tea plants in responses to biotic stresses and abiotic stresses. This review provides a reference for future research on the JA signaling pathway in terms of its regulation against various stresses of tea plants. Due to the lack of a genetic transformation system, the JA pathway of tea plants is still in the preliminary stages. It is necessary to perform further efforts to identify new components involved in the JA regulatory pathway through the combination of genetic and biochemical methods.
茶树由于其固着的生活方式和多年生常绿的特性，必须适应频繁的挑战性环境。茉莉酸不仅调节茶树对生物胁迫的反应，包括食草动物的攻击和病原体的感染，还调节对非生物胁迫的耐受性，如极端天气条件和渗透胁迫。在这篇综述中，我们总结了最近关于茉莉酸（JA）生物合成和信号通路的进展，以及茉莉酸在茶树响应生物胁迫和非生物胁迫中的介导机制。这为今后研究 JA 信号通路对茶树各种胁迫的调控提供了参考。由于缺乏遗传转化系统，茶树的 JA 途径仍处于初级阶段。有必要通过遗传和生化方法的结合，进一步努力鉴定参与 JA 调节途径的新成分。
