Abstract: Phosphatidic acid (PA), a second messenger, is considered to be a lipid signal whose level increases transiently in response to various challenges. The main production of PA derives from phospholipase D (PLD) and phospholipase C/diacylglycerol kinase (PLC/DGK) pathways. On the basis of differences in biochemical properties, catalytic mechanisms, and heterogeneities of PLDs, which are activated under specific stress, diverse PA molecular species composition would be formed response to various stresses conditions. PA is involved in various physiological processes. It acts as messenger by binding target proteins and regulating proteins positively and negatively in stomatal closure pathways. In this review, we first summarize biochemical properties of PA and the effects of PA on protein interaction and then provide insights into some crucial and urgent issues as well as directions for future research.
