Glutathione is a key antioxidant metabolite to cope with mercury and cadmium stress

Glutathione (GSH) plays a dual role under heavy metal stress, as antioxidant metabolite and as precursor of phytochelatins (PCs). Studying the responses of the GSH metabolism to heavy metals is important to improve tolerance. We studied the oxidative stress signature of three γ-glutamylcysteine synthetase (γECS) Arabidopsis thaliana allele mutants (rax1-1… CONTINUE READING
