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 GSHennullThesis
