Heavy metal hyperaccumulating plants: how and why do they do it? And what makes them so interesting?
An overview of literature discussing the phytoremediation capacity of hyperaccumulators to clean up soils contaminated with heavy metals and the possibility of using these plants in phytomining is presented. Expand
Abstract Changes in the amounts of ascorbic acid, dehydroascorbic acid and glutathione and in the levels of related enzyme activities were studied in Sporobolus stapfianus leaves, aExpand
Trace element behaviour at the root-soil interface: Implications in phytoremediation
Abstract Free of human interference the soil trace element content is largely dependent on that of the soil parent material and acting weathering processes. An increasingly industrialised societyExpand
Phytoextraction of metals from a multiply contaminated soil by Indian mustard.
A significant enhancement of metal uptake was observed in NTA-treated plants for Cu and Zn, and Indian mustard shoot dry weights suffered significant reductions following NTA application. Expand
Lipids and NADPH-dependent superoxide production in plasma membrane vesicles from roots of wheat grown under copper deficiency or excess.
Plasma membranes of wheat grown under metal deficiency and excess showed increased NADPH-dependent superoxide-producing oxidase activities, whereas membrane-bound lipoxygenase was not increased or activated due to Cu treatments. Expand
Antioxidative responses of Calendula officinalis under salinity conditions.
To gain a better insight into long-term salt-induced oxidative stress, some physiological parameters in marigold under 0, 50 and 100 mM NaCl were investigated and changes in catalase and peroxidase activities, both in roots and in leaves, may be important in H2O2 homeostasis. Expand
The use of NTA and EDDS for enhanced phytoextraction of metals from a multiply contaminated soil by Brassica carinata.
Brassica carinata demonstrated the ability to survive and tolerate the presence of more metals simultaneously and was the species that accumulated the highest amounts of metals in shoots without suffering a significant biomass reduction. Expand
Thylakoid-bound and stromal antioxidative enzymes in wheat treated with excess copper
Copper is a catalyst in the formation of reactive free radicals and its toxicity may be due, at least in part, to oxidative damage. The response of thylakoid-bound and stromal antioxidative enzymesExpand
The role of the glutathione system during dehydration of Boea hygroscopica
Plants of Boea hygroscopica F. Muell were subjected to dehydration for 25 days until the relative water content was 23%. The rate of water loss was very slow during the first 12 days of dehydrationExpand
Copper excess triggers phospholipase D activity in wheat roots.
Wheat seedlings (Triticum durum Desf.) were incubated in 100muM Cu(2+) for different periods of time and a rapid intake of copper ions into the roots was observed, indicating a very rapid induction of phospholipase D (PLD) activity. Expand
