Pruski}, volume={31}, url={https://revistas.uclave.org/index.php/bioagro/article/view/2641}, abstractNote={<p>Cadmium (Cd<sup>2+</sup>) is a pollutant of great environmental concern due to its multiple origins (natural and anthropogenic), the ability to accumulate in organs and tissues, and the deleterious effects it can cause in organisms. In the present study, we investigated the effects of Cd<sup>2+</sup> exposure on <em>Sphagneticola trilobata</em> plants. We evaluated the accumulation of Cd<sup>2+</sup>, the plant biomass, the content of chlorophyll, soluble sugars, proteins and the production of malondialdehyde and thiols as markers of oxidative stress and tolerance, respectively. The Cd<sup>2+</sup> content in the plant organs increased proportionally to the concentration of CdCl<sub>2</sub> in the environment, reaching accumulatively 1306, 193 and 52 mg·kg<sup>-1</sup> in roots, stems and leaves, respectively. Some toxic effects such as a decrease in the root biomass, alterations in the polypeptide pattern of the leaves, reduction in the chlorophyll content, and an increase in the amount of malondialdehyde was observed at higher concentrations of CdCl<sub>2</sub>. An increase in the content of soluble sugars was also seen, which are markers of tolerance associated with a protection mechanism against the oxidative stress. In addition, an increase on heavy metals chelating thiols such as L-cysteine, glutathione and various phytochelatins was obtained in the plant roots. Our results demonstrated that <em>S. trilobata</em> is capable of accumulating Cd<sup>2+ </sup>and possesses tolerance mechanisms that make this plant an excellent option to be used for Cd<sup>2+ </sup>phytoremediation.</p&gt;}, number={2}, journal={Bioagro}, author={Pernía, Beatriz and Calabokis, Maritza and Noris, Karen and Bubis, José and Guerra, Mayamaru and Castrillo, Marisol}, year={2020}, month={Apr.}, pages={133-142} }
