Rapid alteration of cellular redox homeostasis upon exposure to cadmium and mercury in alfalfa seedlings.

Abstract

Here, the kinetics of oxidative stress responses of alfalfa (Medicago sativa) seedlings to cadmium (Cd) and mercury (Hg) (0, 3, 10 and 30 microm) exposure, expanding from a few minutes to 24 h, were studied. Intracellular oxidative stress was analysed using 2',7'-dichlorofluorescin diacetate and extracellular hydrogen peroxide (H(2)O(2)) production was… (More)
