Five-day-old etiolated seedlings of maize (Zea mays L.) were used to study the kinetics of hydrogen peroxide formation upon lowering growth temperature from 25 to 6°C. The total content of hydrogen peroxide in root and shoot tissues increased by 30–40% after 2-h cooling compared to the control level but returned to the initial level or decreased even lower(More)
Kinetics of superoxide anion generation by the isolated plasma membrane was determined by the rate of formazan formation from XTT in the presence of NADPH or NADH. The plasma membrane was prepared from (control) etiolated maize seedlings grown at 25°C and from (cooled) seedlings incubated at 6°C for the last day. Membrane vesicles from the control plants(More)
Blue native electrophoresis (BN-PAGE) is presently considered as one of effective methods for the identification of membrane protein complexes. The choice of a nonionic detergent and the detergent to protein ratio are critically important. Our experiments with plasma membranes of etiolated pea (Pisum sativum L.) seedlings showed that various nonionic(More)
Plasma membrane isolated from microsomal membranes of pea seedling root and shoot cells by means of aqueous two-phase polymer system was separated by flotation in discontinuous OptiPrep gradient into “light” (≤1.146 g/cm3) and “heavy” (≥1.146 g/cm3) fractions. Osmotic water permeability of plasma membrane and its two fractions was investigated by inducing(More)
