Potential of Phalaris arundinacea L. for phytoremediation
Languages of publication
The influence of a xenobiotic, a substrate and elicitors on glutathione S-transferase, peroxidase activities and glutathione concentration was studied in reed cannarygrass. The induction of both enzymes? activities and glutathione concentrations by 4-chlorophenol (xenobiotic), benzyl isothiocyanate (substrate), salicylic acid and 3-aminobutyric acid (substrate) was shown. Salicylic acid treatment increased glutathione level, but did not decrease GSH/GSSG ratio. The ability of reed cannarygrass to adsorb 4-chlorophenol in the hydroponic culture was demonstrated. The obtained results suggest that the reed cannarygrass has significant potential to conjugate xenobiotics with glutathione and it may be useful for phytoremediation.
