Phytotoxicity of cadmium ions on germinating seedlings of mung bean (Phaseolus vulgaris): Involvement of lipid peroxides in chlorphyll degradation
Abstract
Germinating seedlings of mung bean (Phaseolus vulgaris L. cv. K‐16) were treated with different concentrations of cadmium acetate (10, 50 and 100 μ M). Cd 2+ lowered the chlorophyll and heme levels. The level of lipid peroxides were higher on day 3 than on day 6. However, Cd 2+ treatment significantly enhanced the level of lipid peroxides. Similarly, a dose‐dependent induction of lipoxygenase (EC 1.13.11.12) activity was observed with Cd 2+ treatment. Further, the activities of antioxidant enzymes such as superoxide dismutase (EC 1.15.1.1) and catalase (EC 1.11.1.6) were decreased. Our results suggest that lipoxygenase‐mediated accumulation of lipid peroxides on the one hand and inhibition of free radical scavenging enzymes like superoxide dismutase and catalase on the other caused a pronounced reduction in the chlorophyll and heme levels of the seedlings. The experiments conducted on the effect of Cd 2+ on dark‐grown seedlings did not conform with the result of light‐grown seedlings. Though chlorophyll and heme levels decreased in a dose‐dependent manner, no accumulation of lipid peroxides was observed, suggesting that the inhibition of chlorophyll synthesis by Cd 2+ is achieved both by reaction with constituent biosynthetic enzymes as well as peroxide‐mediated degradation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
