Drought Stress Effects on Root Cell Membranes
Drought stress or consecutive periods of drought stress implies drastic changes in the root cell membranes of higher plants. We have found, in previous investigations on lipid analysis of whole roots, changes in the total amount of acyl lipids, the unsaturation degree and the dry weight ratio root/shoot, the molar ratio free sterols/phospholipids and the level of abscisic acid. These investigations were performed on oats and rape (Liljenberg and Kates, 1982; Liljenberg and Kates, 1985; Svenningsson and Liljenberg, 1986).
