植物体内磷脂酶D（PLD）的活性在不同的高渗胁迫条件下，如脱水、干旱和盐胁迫下均会升高。最近的研究结果开始阐明PLD参与响应水分亏缺和盐度。不同的PLD在这些反应中具有独特和重叠的功能。PLD α 1促进气孔关闭，减少水分损失。PLD α 1和PLD δ参与了幼苗对盐胁迫的耐受性。PLD α 3和PLD β 4增强植物生长和高渗耐性。不同的磷脂酶D调节磷脂酸（PA）的产生，磷脂酸是植物响应环境胁迫的一类关键脂质介质。进一步研究激活不同PLD的上游调节因子以及PLD和PA的下游效应因子有可能揭示细胞膜上的刺激感知与细胞内对干旱和盐胁迫的反应之间的联系。
The activity of phospholipase D (PLD) in plants increases under different hyperosmotic stresses, such as dehydration, drought, and salinity. Recent results begin to shed light onto the involvement of PLD in response to water deficits and salinity. Different PLDs have unique and overlapping functions in these responses. PLD alpha 1 promotes stomatal closure and reduces water loss. PLD alpha 1 and PLD delta are involved in seedling tolerance to salt stress. PLD alpha 3 and PLD epsilon enhance plant growth and hyperosmotic tolerance. The different PLDs regulate the production of phosphatidic acid (PA) that is a key class of lipid mediators in plant response to environmental stresses. Further studies on the upstream regulators that activate different PLDs and the downstream effectors of PLDs and PA have the potential to unveil the linkage between the stimulus perception at the cell membrane to intracellular responses to drought and salinity stresses.
