Influence of chromium salts on increased lipid peroxidation and differential pattern in antioxidant metabolism in Pistia stratiotes L
In this work, the changing effect of different concentrations (0, 0.01, 0.1, 1, 10mM) of hexavalent and trivalent chromium on different biochemical parameters along with antioxidant enzymes was investigated on water lettuce (Pistia stratiotes L.) in order to know the possible involvement of this met...

| description | In this work, the changing effect of different concentrations (0, 0.01, 0.1, 1, 10mM) of hexavalent and trivalent chromium on different biochemical parameters along with antioxidant enzymes was investigated on water lettuce (Pistia stratiotes L.) in order to know the possible involvement of this metal in oxidative injury, besides the activities of antioxidant enzymes leading to biochemical and oxidative aberration induced by elevated concentrations. Both in roots and shoots, Cr produced a significant increase in enzymic and non-enzymic antioxidants, except in catalase (CAT) activity where a strong accumulation of hydrogen peroxide was indicated, suggesting an imposition of oxidative stress. The observation showed an uptake of chromium by P. stratiotes L. as well as increase in activity of antioxidants, as the concentrations and their duration of treatment increased. The activity of antioxidative enzymes determined the steady-state levels of ROS in the cell. The augmentation of antioxidative defense plays a key role in regulating the oxidative stress. This pointed to the possibility in induction of oxidative stress, with the increasing lipid peroxidation, followed by a differential pattern in antioxidant metabolisms by chromium ions in P. stratiotes L. |
