Abstract
Permeability of erythritol to lipid bilayers composed of several types of phospholipids is enhanced by the plant hormones abscisic acid and kinetin. Abscisic acid increases permeability in its undissociated form and requires the presence of phosphatidylethanolamine in the bilayers. The abscisic acid-induced permeability can be completely inhibited by kinetin. A new model based on the kinetin blockage of abscisic acid-phosphatidylethanolamine channels is proposed to explain the antagonistic effect of these two hormones on membranes.
