The removal of inorganic contaminants by plants is termed phytoextraction. Recent studies
have looked at the feasibility of phytoextraction, and demonstrate that both good biomass …

This article deals with the advances and implication of phytoremediation technologies with
emphasis on remediation of toxic heavy metals from contaminated soil. Most of the …

Heavy metals are required in plants as essential micronutrients or act as toxic compounds.
How do plants perceive heavy metals and which signalling cascades are triggered leading …

Plants growing in metal-enriched substrates take up metals to varying degrees in response
to external and internal factors. The tacit assumption that a plant can thus act as an …

This chapter presents knowledge of the mechanisms and genetics of heavy metal tolerance
in hyperaccumulating and nonhyperaccumulatitig metallophytes. Strongly heavy metal …

Some plants hyperaccumulate metals or metalloids to levels several orders of magnitude
higher than other species. This intriguing phenomenon has received considerable attention …

Metal hyperaccumulation, in which plants store exceptional concentrations of metals in their
shoots, is an unusual trait whose evolutionary and ecological significance has prompted …

The concentrations in plant parts depend both on intrinsic and extrinsic factors and vary
greatly for different species and for different metals. Responses by plant species to exposure …

Metal toxicity for living organisms involves oxidative and/or genotoxic mechanisms. Plant
protection against metal toxicity occurs, at least in part, through control of root metal uptake …

The elucidation of a natural strategy for metal hyperaccumulation enables the rational
design of technologies for the clean-up of metal-contaminated soils. Organic acid has been …
