Abstract
Plant accumulation of a given metal is a function of uptake capacity and intracellular
binding sites. At every level, concentration and affinities of chelating molecules, as well
as the presence and selectivity of transport activities, affect metal accumulation rates. An
important pathway by which plants avoid the heavy metal stress is by the production of
heavy metal binding peptides, phytochelatins, or their precursor glutathione. An enzyme
named phytochelatin synthase catalyses PC synthesis from GSH
