Selenium reduces cadmium uptake and mitigates cadmium toxicity in rice.
J Hazard Mater. 2012 Oct 15; 235-236:343-51.JH

Abstract

Hydroponic experiments were performed to investigate physiological mechanisms of selenium (Se) mitigation of Cd toxicity in rice. Exogenous Se markedly reduced Cd concentration in leaves, roots, and stems. Addition or pretreatment of 3 μM Se in 50 μM Cd solution significantly addressed Cd-induced growth inhibition, recovered root cell viability, and dramatically depressed O(2)(-), H(2)O(2), and malondialdehyde (MDA) accumulation. Supplemental Se counteracted 50 μM Cd-induced alterations of certain antioxidant enzymes, and uptake of nutrients, e.g. depressed Cd-induced increase in leaf and root superoxide dismutase (SOD) and leaf peroxidase (POD) activities, but elevated depressed catalase (CAT) activity; decreased Cd-induced high S and Cu concentrations in both leaves and roots. External Se counteracted the pattern of alterations in ATPase activities induced by Cd, e.g. significantly elevated the depressed root H(+)- and Ca(2+)-ATPase activities, but decreased the ascent root Na(+)K(+)-ATP activity. Results indicate that alleviated Cd toxicity by Se application is related to reduced Cd uptake and ROS accumulation, balanced nutrients, and increased H(+)- and Ca(2+)-ATPase activities in rice.
