摘要

三酰甘油（TAG）是生物系统中能量密度最高的还原碳储存形式之一。TAG 代谢在细胞能量平衡、脂质平衡、细胞生长和应激反应中发挥着关键作用。在高等植物、微藻和真菌中，TAG 通过依赖酰基-CoA 和不依赖酰基-CoA 的途径组装，分别由二酰基甘油（DAG）酰基转移酶和磷脂：DAG酰基转移酶（PDAT）催化。本综述概述了目前对 PDAT 生理功能的理解。重点是它们在脂质重塑和脂质平衡中的作用，以应对非生物胁迫或脂质代谢紊乱。

Physiological Functions of Phospholipid:Diacylglycerol Acyltransferases.

Triacylglycerol (TAG) is among the most energy dense storage forms of reduced carbon in living systems. TAG metabolism plays critical roles in cellular energy balance, lipid homeostasis, cell growth and stress responses. In higher plants, microalgae and fungi, TAG is assembled by acyl-CoA-dependent and acyl-CoA-independent pathways catalyzed by diacylglycerol (DAG) acyltransferase and phospholipid:DAG acyltransferase (PDAT), respectively. This review contains a summary of the current understanding of the physiological functions of PDATs. Emphasis is placed on their role in lipid remodeling and lipid homeostasis in response to abiotic stress or perturbations in lipid metabolism.

期刊介绍： Plant & Cell Physiology (PCP) was established in 1959 and is the official journal of the Japanese Society of Plant Physiologists (JSPP). The title reflects the journal''s original interest and scope to encompass research not just at the whole-organism level but also at the cellular and subcellular levels. Amongst the broad range of topics covered by this international journal, readers will find the very best original research on plant physiology, biochemistry, cell biology, molecular genetics, epigenetics, biotechnology, bioinformatics and –omics; as well as how plants respond to and interact with their environment (abiotic and biotic factors), and the biology of photosynthetic microorganisms.
