Plant Phospholipase D
Phospholipase D (PLD) is involved in different plant processes, ranging from responses to abiotic and biotic stresses to plant development and seed quality. The PLD family consists of multiple members that have distinguishable biochemical and regulatory properties. The differential activation of different PLDs regulates the temporal and spatial production of the lipid messenger, phosphatidic acid (PA), and the selective hydrolysis of membrane lipids. PLD and PA may regulate plant functions through their effects on signal transduction, cytoskeletal reorganization, vesicular trafficking, membrane remodeling, and/or lipid degradation, and the modes of action may differ depending on the specific PLDs and stimulations. The molecular heterogeneity of PLDs plays important roles in their different functions.
