Function
Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond to generate phosphatidic acids (PA) (PubMed:18364466). Active with phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and phosphatidylserine (PS) as substrates (PubMed:18364466). No activity toward phosphatidylinositol (PI) or PIP2 (PubMed:18364466). Positively mediates plant responses to hyperosmotic stresses and promotes root growth, flowering, and stress avoidance (PubMed:18364466, PubMed:19704505). Not involved in the abscisic acid regulation of stomatal movement and transpirational water loss (PubMed:18364466).
