Abstract

• Pteris vittata was the first identified arsenic (As) hyperaccumulator. Here we investigated whether phytochelatins (PCs) are involved in the hypertolerance of arsenic by P. vittata. • P. vittata was exposed to 0-500 μM arsenate for 5 d, or to 50 μM arsenate for 0-7 d. In addition, L-buthionine-sulphoximine (BSO), an inhibitor of γ-glutamylcysteine synthetase, was used in combination with different arsenate exposures. The relationships between As accumulation and the concentrations of PCs and glutathione (GSH) were examined. • PC synthesis was induced upon exposure to arsenate in P. vittata, with only PC
