A dual effect of Se on Cd toxicity: evidence from plant growth, root morphology and responses of the antioxidative systems of paddy rice

Ministry of Agriculture, Agro-Environmental Protection Institute, Tianjin 300191, China
Abstract:
Aims It is well established that low levels of selenium (Se) are protective against low levels of cadmium (Cd) toxicity and can significantly reduce Cd uptake in plants. However, our previous study reported that the addition of Se hampered the growth of paddy rice exposed to high levels of Cd and enhanced Cd uptake. The relevant mechanisms underlying the dual effects of Se on Cd uptake and toxicity are unclear.
