Phospholipid signaling in plants: holding on to phospholipase D

Abstract

Plant cells contain various phospholipase-based signaling pathways. In fact, their repertoire of phospholipase D (PLD) molecules far outnumbers those of mammalian and yeast cells. Munnik and Musgrave take a broad look at PLD function in animal, yeast, and plant cells, and suggest that a PLD-based connection between membranes and microtubules is a biological property worth considering across species.
