PLANT PHOSPHOLIPASE D

Plant PIP2-dependent phospholipase D activity is regulated by phosphorylation.

Phospholipase D (PLD) forms the major family of phospholipases that was first discovered and cloned in plants. In this report we have shown, for the first time, that C2 phosphatidylinositol-4,5-bisphosphate (PIP2)-dependent PLD(s) from 5 day hypocotyls of Brassica oleracea associated with plasma membrane is covalently modified-phosphorylated. Pre-incubation of the plasma membrane fraction with ...

Update on Phospholipase D and Phosphatidic Acid in Signaling Regulatory Functions of Phospholipase D and Phosphatidic Acid in Plant Growth, Development, and Stress Responses

Phospholipase D (PLD) hydrolyzes membrane lipids to generate phosphatidic acid (PA) and a free-head group (Fig. 1), and this activity is widespread in plants. Recent results indicate that PLD plays multiple regulatory roles in diverse plant processes, including abscisic acid (ABA) signaling, programmed cell death, root hair patterning, root growth, freezing tolerance, and other stress responses...

Water deficit triggers phospholipase D activity in the resurrection plant Craterostigma plantagineum.

Phospholipids play an important role in many signaling pathways in animal cells. Signaling cascades are triggered by the activation of phospholipid cleaving enzymes such as phospholipases C, D (PLD), and A(2). Their activities result in the formation of second messengers and amplification of the initial signal. In this study, we provide experimental evidence that PLD is involved in the early ev...
