中文摘要：

磷脂酶D（PLD）是一种重要的磷脂水解酶，在植物细胞中普遍存在。磷脂酶D能激活许多重要的细胞生理功能，包括蒯控细胞膜的重建、跨膜信号传导及细胞内调控、细胞骨架绀装、防御反应以及种子萌发和植物的衰老等。对磷脂酶D的基本特性、磷脂酶D基因特异性表达模式及其活性抑制与植物衰老的关系进行了综述，并探讨和展望了今后植物磷脂酶D基因的研究方向。

英文摘要：

Phospholipase D （PLD） is an important phospholipid hydrolase prevalently existing in plant cells. PLD plays an important role in regulation of many critical cellular functions, including regulation of cell membrane reconstruction, cellular signal transduction, intracellular regulation, cellular backbone formation, defense responses, seed germination and plant senescence, etc. The basic characteristic of PLD, differential expression pattern of PLD gene and senescence-related physiological and biochemical processes involving PLD were comprehensively reviewed. The relationship between PLD activity inhibition and senescence was discussed, as well as the research direction of PLD gene in the future was prospected.
