Nickel is an economically important metal and phytotechnologies are being developed to limit the impact of nickel mining on the environment. More than 300 plant species are known to hyperaccumulate nickel. However, our knowledge of the mechanisms involved in nickel accumulation in plants is very limited because it has not yet been possible to study these hyperaccumulators at the genomic level. ...

Hyperaccumulators are plants that can extract heavy metal ions from the soil and translocate those ions to the shoots, where they are sequestered and detoxified. Hyperaccumulation depends not only on the availability of mobilized metal ions in the soil, but also on the enhanced activity of metal transporters and metal chelators which may be provided by the plant or its associated microbes. The ...

The role of endophytic fungi isolated from different populations European Ni hyperaccumulators was investigated in regard to the microorganisms' ability enhance hyperaccumulation Noccaea caerulescens. Effects particular species on adaptation N. caerulescens excess were tested by co-cultivation with single strains fungi. Seven these had a positive effect plant biomass production, whereas two inh...

Heavy metal contaminants are a serious problem worldwide to human health, animals and some plants. Phytoremediation, is a promising technology, which has gained wide acceptance in remediating the contaminants from the soil, which uses green plants known as hyperaccumulators. Biochemical mechanisms such as adsorption, transport, accumulation and translocation that are adopted by plants are of su...

Metal hyperaccumulator plants accumulate and detoxify extraordinarily high concentrations of metal ions in their shoots. Metal hyperaccumulation is a fascinating phenomenon, which has interested scientists for over a century. Hyperaccumulators constitute an exceptional biological material for understanding mechanisms regulating plant metal homeostasis as well as plant adaptation to extreme meta...

Abstract Purpose Thallium (Tl) is one of the most toxic elements known and its contamination an emerging environmental issue associated with base metal (zinc-lead) mining wastes. This study investigated nature Tl tolerance accumulation in Silene latifolia , which has so far only been reported from field-collected samples. Methods was grown hydroponics at different concentrations (0, 2.5, 5, 30 ...

In recent years, heavy metal pollution in soil has become a serious problem. Remediation technologies have been developed, such as physical remediation, chemical microbial remediation and other technologies. Among them, phytoremediation widely used practice. this paper, the present situation of China, research progress technology contaminated by hyperaccumulators are reviewed, to help with foll...

The so-called hyperaccumulator plants are capable of storing hundred or thousand times bigger quantities heavy metals than normal plants, which makes hyperaccumulators very useful in fields such as phytoremediation and phytomining. Among these there many serpentinophytes, i.e., that grow exclusively on ultramafic rocks produce soils with a great proportion metals. Even though multiple classific...
