生物合成/代谢、感知/信号和运输是植物激素作用的三个基本方面。茉莉酸（Jasmonates，JA），包括茉莉酸（jasmonic acid，JA）和相关的氧化脂蛋白，参与了一系列生态学相互作用的调控，以及整合这些相互作用的发育程序。茉莉酰-异亮氨酸（JA-Ile）是最具生物活性的茉莉酸，其受体Skp 1-Cullin 1-F-box-type（SCF）蛋白泛素连接酶复合物SCFCOI 1-JAZ在细胞核中对JA-Ile的感知可解除靶基因的转录抑制。JA的生物合成和代谢发生在质体、过氧化物酶体、细胞质、内质网和液泡中，而JA-Ile水平的传感发生在细胞核中。越来越明显的是，许多转运蛋白，特别是茉莉酸转运蛋白（JAT）家族的成员，位于内膜以及质膜，构成了一个网络，用于调节和协调的代谢流量和信号的JAs。本文就茉莉酸的代谢、信号转导、转运等方面的研究进展作一综述。本文还讨论了转运蛋白介导的细胞-细胞转运在驱动茉莉酸长距离转运和信号传导中的作用。JA合成、代谢和信号传导的复杂细胞内区室化为协调JA代谢通量和信号传导动力学提供了新的调节层。位于内膜和质膜上的许多转运蛋白构成了促进JAs转运的网络。在这里，JAs的代谢，信号和运输的审查，通过透镜的细胞内和细胞间的分布。
Biosynthesis/metabolism, perception/signaling, and transport are three essential aspects of the actions of phytohormones. Jasmonates (JAs), including jasmonic acid (JA) and related oxylipins, are implicated in the regulation of a range of ecological interactions, as well as developmental programs to integrate these interactions. Jasmonoyl-isoleucine (JA-Ile) is the most bioactive JAs, and perception of JA-Ile by its coreceptor, the Skp1-Cullin1-F-box-type (SCF) protein ubiquitin ligase complex SCFCOI1-JAZ, in the nucleus derepresses the transcriptional repression of target genes. The biosynthesis and metabolism of JAs occur in the plastid, peroxisome, cytosol, endoplasmic reticulum, and vacuole, whereas sensing of JA-Ile levels occurs in the nucleus. It is increasingly apparent that a number of transporters, particularly members of the jasmonates transporter (JAT) family, located at endomembranes as well as the plasma membrane, constitute a network for modulating and coordinating the metabolic flux and signaling of JAs. In this review, we discuss recent advances in the metabolism, signaling, and especially the transport of JAs, focusing on intracellular compartmentation of these processes. The roles of transporter-mediated cell-cell transport in driving long-distance transport and signaling of JAs are also discussed. The complex intracellular compartmentation of JA synthesis, metabolism, and signaling provides a new regulatory layer for coordinating JA metabolic flux and signaling dynamics. A number of transporters located at endomembranes and the plasma membrane constitute a network that facilitates the transport of JAs. Here, the metabolism, signaling, and transport of JAs are reviewed through the lens of their intra- and intercellular distributions.
