Role of Zinc in Plasma Membrane Integrity and O2− -Generating NADPH Oxidase Activity
Part of the
NATO ASI Series
book series (NSSA, volume 7)
The NADPH− dependent superoxide radical (O2 −) generation and plasma membrane permeability were studied in roots of cotton (Gossypium hirsutum c.) plants grown in nutrient solution with different Zn concentrations. Zinc deficiency increased plasma membrane permeability indicated by efflux of K+; NO3 −, amino acids, sugars and phenolics. Resupply of Zn to deficient plants for 12 h substantially decreased this leakage (1).
