High salinity threatens crop production by harming plants and interfering with their development. Plant cells respond to salt stress in various ways, all of which involve multiple components such as proteins, peptides, lipids, sugars, and phytohormones. Phospholipids, important components of bio-membranes, are small amphoteric molecular compounds. These have attracted significant attention in recent years due to the regulatory effect they have on cellular activity. Over the past few decades, genetic and biochemical analyses have partly revealed that phospholipids regulate salt stress response by participating in salt stress signal transduction. In this review, we summarize the generation and metabolism of phospholipid phosphatidic acid (PA), phosphoinositides (PIs), phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG), as well as the regulatory role each phospholipid plays in the salt stress response. We also discuss the possible regulatory role based on how they act during other cellular activities.
高盐度通过损害植物并干扰其发育来威胁作物生产。植物细胞以多种方式对盐胁迫作出反应，所有这些方式都涉及蛋白质、肽、脂质、糖和植物激素等多种成分。磷脂是生物膜的重要组成部分，是小型两性分子化合物。近年来，由于它们对细胞活性具有调节作用，因此受到了广泛关注。在过去几十年中，遗传和生化分析部分揭示了磷脂通过参与盐胁迫信号转导来调节盐胁迫反应。在这篇综述中，我们总结了磷脂酸（PA）、磷酸肌醇（PIs）、磷脂酰丝氨酸（PS）、磷脂酰胆碱（PC）、磷脂酰乙醇胺（PE）和磷脂酰甘油（PG）的生成和代谢，以及每种磷脂在盐胁迫反应中所起的调节作用。我们还根据它们在其他细胞活动中的作用方式讨论了可能的调节作用。
