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.

细胞膜是感知环境刺激的起始部位，磷脂是细胞膜的基本和重要成分。磷脂酶水解膜脂以产生各种细胞介质。这些磷脂酶衍生产物，如甘油二​​酯、磷脂酸、磷酸肌醇、溶血磷脂和游离脂肪酸，作为第二信使，在植物生长、发育和胁迫反应过程中的信号转导中起着至关重要的作用。本综述侧重于几个磷脂酶家族的结构、底物特异性、反应要求和作用机制。它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，它将突出行动机制中的一些关键知识差距，
