摘　　要：磷脂酶C(phospholipase C,PLC)是参与脂质和Ca^(2+)依赖信号通路的重要调节酶,它能将磷脂酰肌醇4,5-二磷酸(PIP_(2))水解生成2个重要的第二信使分子:脂类的二酰甘油和可溶性分子肌醇1,4,5-三磷酸。磷脂酶C根据其水解磷脂的底物不同,可分为磷脂酰肌醇特异性磷脂酶C和非特异性磷脂酶C。植物PLC基因通过调控各种信号途径,从而在植物的非生物胁迫(渗透胁迫、低温胁迫、干旱胁迫等)以及生物胁迫的应答过程中具有重要作用。综述了植物磷脂酶C分类、结构、生化特性和生理功能,并对相关领域的研究方向进行了展望。Phospholipase C(PLC)is an important enzyme that plays an important role in lipid and Ca^(2+) dependent signaling pathways.It hydrolyzes phosphatidylinositol 4,5-diphosphate(PIP_(2))into two important second messenger molecules:the lipid diacylglycerol and the soluble molecule inositol 1,4,5-triphosphate.Phospholipase C can be classified into phosphatidylinositol-specific phospholipase C and non-specific phospholipase C based on the respective to different substrates.Plant PLC gene plays an important role in plant response to abiotic stress(osmotic stress,low temperature stress,drought stress etc.)and biological stress via regulating varied signaling pathways.In this review,the classification,structure,biochemical characteristics and physiological functions of phospholipase C in plants are discussed,and the future directions of the research are prospected.
