Phytochelatins (PCs) are small, cysteine-rich peptides, known to play a major role in detoxification of both cadmium and arsenic. The aim of this study was to determine whether overexpression of either of two PC synthase (PCS) genes, AtPCS1 and CePCS in Nicotiana tabacum (previously shown to cause decrease and increase, respectively, of cadmium tolerance of tobacco - Wojas et al., 2008) also contributes to such contrasting phenotypes with respect to arsenic (As) tolerance and accumulation, and… CONTINUE READING
