Jasmonates (JAs) play vital roles in regulating a range of plant growth and development processes including seed germination, seedling development, reproduction, formation and development of storage organs, and senescence. JAs are also involved in the regulation of plant responses to environmental stimuli. The biosynthesis of JAs takes place in three different subcellular compartments, namely, the chloroplast, peroxisome, and cytoplasm. JAs activate the expression of JA-responsive genes by degrading jasmonate zinc-finger-inflorescence meristem (Zim) domain (JAZ) repressors via the E3 ubiquitin-ligase Skp/Cullin/F-box protein CORONATINE INSENSITIVE1 (COI1) complex (SCF) by using 26S proteasome. Calcium, reactive oxygen species (ROS), mitogen-activated protein kinase (MAPK), and nitric oxide (NO) are involved in the regulation of the biosynthesis and signaling of JAs in plants. Among these signaling molecules, calcium is one of the most important within plant cells. In plants, intracellular calcium levels change in response to JAs, resulting in calcium signatures with temporal and spatial features. Calcium channels are involved in the generation of calcium signatures. Calcium sensors, including calmodulins (CaMs), CaM-like proteins (CMLs), calcineurin B-like proteins (CBLs), and calcium-dependent protein kinases (CDPKs), can act to regulate the biosynthesis and signaling of JAs.
茉莉酸（JAs）在调节植物生长和发育过程中发挥着重要作用，包括种子萌发、幼苗发育、繁殖、贮藏器官的形成和发育以及衰老。JAs 还参与植物对环境刺激的调节。JAs 的生物合成发生在三个不同的亚细胞隔室中，即叶绿体、过氧化物酶体和细胞质。JAs 通过降解茉莉酸锌指花序分生组织（Zim）域（JAZ）抑制剂，通过 E3 泛素连接酶 Skp/Cullin/F-box 蛋白 CORONATINE INSENSITIVE1（COI1）复合物（SCF），利用 26S 蛋白酶体激活 JA 反应基因的表达。钙、活性氧（ROS）、丝裂原激活蛋白激酶（MAPK）和一氧化氮（NO）参与植物中 JAs 的生物合成和信号转导的调节。在这些信号分子中，钙是植物细胞内最重要的信号分子之一。在植物中，细胞内钙水平响应 JAs 而变化，导致具有时间和空间特征的钙特征。钙通道参与钙特征的产生。钙传感器，包括钙调蛋白（CaM）、钙调蛋白样蛋白（CML）、钙调磷酸酶 B 样蛋白（CBL）和钙依赖蛋白激酶（CDPK），可以调节 JAs 的生物合成和信号转导。
