In the plant kingdom, the pathway of synthesis of 3- and 4-phosphorylated phosphoinositides has been described only in Spirodela polyrhiza L. [1]. If animal models of phosphoinositide metabolism are to be applied to plants, it is imperative to determine the route of synthesis of phosphoinositides in other members of the plant kingdom in which signaling functions for phosphoinositides and inositol phosphates have been implicated. Recently, we have rigorously identified 3- and 4-phosphorylated phosphoinositides in stomatal guard cells of Commelina communis L. [2]. In the present work we have set out to determine the metabolic route by which PtdIns(3,4)P and PtdIns(4,5)P synthesis occurs and to examine the metabolic relationship between 3- and 4-phosphoryrated lipids in stomatal guard cells.
