Both the concentration and redox state of glutathione and ascorbate influence the sensitivity of arabidopsis to cadmium Universiteit Hasselt Universiteit Antwerpen
Background and Aims Cadmium (Cd) is a non-essential trace element that elicits oxidative stress. Plants respond to Cd toxicity via increasing their Cd-chelating and antioxidative capacities. They predominantly chelate Cd via glutathione (GSH) and phytochelatins (PCs), while antioxidative defence is mainly based on the use and recycling of both GSH and ascorbate (AsA), complemented by superoxide dismutase (SOD) and catalase (CAT). In addition, ...
