摘 要:
JAZ (Jasmonate ZIM-domain)蛋白是植物中一种重要的负调控因子, 最初从模式植物拟南芥(Arabidopsis thaliana)中分离鉴定。 JAZ蛋白结构包含ZIM、 Jas和NT三个保守结构域。 JAZ蛋白可通过与植物中转录因子或其他蛋白相互作用参与植物生长发育过程中多种生理过程的调控。本文将介绍JAZ蛋白的结构特征, 以及响应茉莉酸(JA)及其他信号通路的转导途径, 并详细综述JAZ蛋白与不同蛋白相互作用参与植物多种生理过程的研究进展, 并进一步展望JAZ蛋白在药用植物中可能的调控作用, 以期为培育活性成分高积累的药用植物新品种提供分子基础和理论依据。

Abstract:
JAZ is an important negative regulator in plants, which was originally identifed and isolated from
the model plant Arabidopsis thaliana. The structure of JAZ contains three conserved domains: ZIM, Jas and NT. JAZs can participate in the regulation of various physiological processes during plant growth and development by interacting with transcription factors or other proteins in plants. This article introduces the structural characteristics of JAZ proteins as well as the signal response pathway to jasmonic acid (JA). Then, the research progress of JAZs involved in various physiological processes of plants is reviewed in detail. We further look forward to the possible regulator role of JAZs in secondary metabolism of medicinal plants. All these will lay a foundation for breeding new medicinal plant varieties with high accumulation of active ingredients.
Key words: JAZ protein; JA pathway; transcription factor; interaction
