Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond to generate phosphatidic acids (PA). Promotes growth and plays a role in nitrogen signaling. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1,2-diacyl-sn-glycero-3-phosphate + choline + H(+) Expressed in roots, leaves, stems, siliques,flowers and inflorescences. C2 domain is a calcium-binding fold, and the binding promotes the protein association with membranes. Reduced growth. Belongs to the phospholipase D family. C2-PLD subfamily.
