Lipid Metabolism in Potato Leaf Disks: Effect of Calmodulin Antagonists

  • Chapter
The Metabolism, Structure, and Function of Plant Lipids

Abstract

Dibucaine (nupercaine), a local anesthetic, was recently shown to alter the lipid composition of barley-root membranes (1). When excised roots were placed in dibucaine there was an increase in the proportions of palmitic, stearic, and oleic acids and a decrease in the proportions of linoleic and linolenic acids. We have recently shown that the rate of autolytic degradation of phospholipids in potato leaf homogenates is inhibited by calmodulin antagonists (which include dibuucaine) and stimulated by calmodulin (2). This study was undertaken in order to investigate the effect of dibucaine and other calmodulin antagonists on the polar lipid composition of potato leaves.
