Cadmium-induced oxidative stress in Saccharomyces cerevisiae.
The present study was undertaken to determine the effect of cadmium (Cd) on the antioxidant status of the yeast Saccharomyces cerevisiae. S. cerevisiae serves as a good eukaryotic model system for the study of the molecular mechanisms of oxidative stress. We investigated the adaptative response of S. cerevisiae exposed to Cd. Yeast cells could tolerate up to 100 microM Cd and an inhibition in t...
متن کاملLeaf Age-Dependent Photoprotective and Antioxidative Response Mechanisms to Paraquat-Induced Oxidative Stress in Arabidopsis thaliana
Exposure of Arabidopsis thaliana young and mature leaves to the herbicide paraquat (Pq) resulted in a localized increase of hydrogen peroxide (H2O2) in the leaf veins and the neighboring mesophyll cells, but this increase was not similar in the two leaf types. Increased H2O2 production was concomitant with closed reaction centers (qP). Thirty min after Pq exposure despite the induction of the p...
متن کاملOxidative stress and antioxidative system in plants
Free radicals and other active derivatives of oxygen are inevitable by-products of biological redox reactions. Reactive oxygen species inactivate enzymes and damage important cellular components. The increased production of toxic oxygen derivatives is considered to be a universal or common feature of stress conditions. Plant and other organisms have evolved a wide range of mechanisms to contend...
متن کاملRemoval of Cadmium and Zinc by Water Hyacinth, Eichhornia crassipes
Toxic heavy metal pollution of water and soil is a major environmental problem, and most conventional remediation approaches do not provide acceptable solutions. Wetland plants are being used successfully for the phytoremediation of trace elements in natural and constructed wetlands. This study demonstrates the phytoremediation potential of water hyacinth Eichhornia crassipes, for the removal o...
متن کاملcadmium-induced stress and antioxidative responses in different brassica napus cultivars
to estimate plant resistance to cadmium chloride (cdcl2) stress for phytoremediation purposes, the effect of cadmium (cd) phytotoxicity was assessed on total soluble protein, chlorophyll (chl) content and antioxidant enzymes in the leaves of three different brassica napus (b. napus) cultivars; mohican, reg.cob and okapi. plants were exposed to three levels of cdcl2 (0.75, 1.5 and 2.25 mm) in ir...
