“…Fresh samples were homogenized in a buffer containing 50 mM Tris-HCl (pH 8.0), 1 mM ascorbic acid, 1 mM DTT, 1 mM EDTA, and 1 mM phenylmethylsulfonyl fluoride (PMSF) according to the method described by Malec et al [35] with modifications. All steps were carried out at 4 • C. The supernatant was applied to a medium Sephadex G-50 column (1.6 cm × 130 cm) equilibrated with 20 mM Tris-HCl buffer (pH 8.0).…”

“…The ability of aquatic plants to accumulate large amounts of HM by producing non toxic complexes [7,8] provides evidence for high resis tance of hydrophytes to elevated concentrations of metals in their habitats and offers prospects for the use of hydrophytes in the environmental monitoring and phytoremediation.…”

Elodea plants (Elodea (Egeria) densa Planch.) were incubated in the presence of individual and mixed 1 µM sulfate salts of Ni, Cd, Cu, Zn, and Mn to study the influence of heavy metals (HM) on shoot growth, structural-and functional parameters of the photosynthetic apparatus, lipid peroxidation, enzymatic activities of the antioxidant defense system (superoxide dismutase and catalase), and the content of non pro tein and protein thiols in leaves. The accumulation of HM in leaves decreased in a row: Mn > Cu > Cd > Zn > Ni. The largest reduction in chlorophyll content was caused by Mn and Cu, whereas the strongest reduction in carotenoid content was induced by Cu. The presence of Cu produced the largest decrease in the maximal quantum efficiency of photosystem II (PSII) (F v /F m ). These changes were paralleled by the shift of the pro /antioxidant balance towards the dominance of oxidative processes. The presence of Cd elevated the content of chlorophyll and carotenoids without altering the photochemical efficiency of PSII; Cd retarded the shoot growth but had no appreciable effect on leaf mesostructure. The addition of the second metal to the growth medium alleviated in most treatments the detrimental action of individual ions owing to the enhanced activities of SOD and catalase and because of the significant increase in the content of non protein thiols. It is supposed that the observed antagonism of metal ions is related to their competitive interactions restricting the entry of HM into the cell.Keywords: Elodea (Egeria) densa, heavy metals, oxidative stress, antioxidant enzymes, photosynthetic appa ratus, chlorophyll fluorescence, non protein and protein thiols.Abbreviations: CAT-catalase; DTNBA-5,5' dithiobis(2 nitrobenzoic) acid; GSH-reduced glutathione; HM-heavy metals; NBT-nitroblue tetrazolium; PSII-photosystem II; SOD-superoxide dismutase; TBA-thiobarbituric acid; F v /F m -maximal quantum yield of PSII photoreaction.

“…Although leaching of nutrients and foliar calcium from plant leaves by acid solution and acid rain has been reported, 6,7 identification of the leaking compounds from Egeria densa by the HCl solution has not been reported as far as we know. On the other hand, peaks at about 470, 625, 646, 664, and 730 nm, which were characteristic absorbance peaks of pigments such as chl a, chl b, and carotenoids, 8 were not observed.…”
