Cell membranes are the initial site of stimulus perception from environment and phospholipids are the basic and important components of cell membranes. Phospholipases hydrolyze membrane lipids to generate various cellular mediators. These phospholipase-derived products, such as diacylglycerol, phosphatidic acid, inositol phosphates, lysophopsholipids, and free fatty acids, act as second messengers, playing vital roles in signal transduction during plant growth, development, and stress responses. This review focuses on the structure, substrate specificities, reaction requirements, and acting mechanism of several phospholipase families. It will discuss their functional significance in plant growth, development, and stress responses. In addition, it will highlight some critical knowledge gaps in the action mechanism, metabolic and signaling roles of these phospholipases and their products in the context of plant growth, development and stress responses.
细胞膜是感知外界环境刺激的初始位点，而磷脂是细胞膜的基本且重要的组成成分。磷脂酶水解膜脂以生成各种细胞介质。这些磷脂酶衍生的产物，如二酰甘油、磷脂酸、肌醇磷酸、溶血磷脂和游离脂肪酸，作为第二信使，在植物生长、发育和应激反应的信号转导中发挥着至关重要的作用。本综述聚焦于几个磷脂酶家族的结构、底物特异性、反应条件及作用机制。将讨论它们在植物生长、发育和应激反应中的功能意义。此外，还将着重指出在植物生长、发育和应激反应背景下，这些磷脂酶及其产物的作用机制、代谢和信号传导作用方面一些关键的知识空白。
