Title
The use of the model species Arabidopsis halleri towards phytoextraction of cadmium polluted soils
Abstract

Phytoremediation consists in treating environmental pollutions through the use of plants and their associated microbes. Phytoremediation can be used for pollutant stabilization, extraction, degradation or volatilization. Cadmium is one of the most toxic trace metallic elements for living organisms and its accumulation in the environment is recognized as a worldwide concern. Plants suitable for efficient pollutant extraction from the soil should combine different characteristics like fast growth, high biomass, high tolerance and high accumulation capacities in harvestable parts. A rare class of plants called hyperaccumulators combines extremely high tolerance degrees and foliar accumulation of trace elements. With regard to cadmium, none of the Cd hyperaccumulators identified has met the criteria for efficient phytoextraction so far. By virtue of genetic engineering it is possible to transfer genes involved in Cd tolerance or accumulation in high biomass plants. Nevertheless, the genetic determinants of Cd hyperaccumulation are far from being understood. It is thus indispensable to acquire more knowledge about these processes. Among Cd hyperaccumulators, Arabidopsis halleri (some populations can hyperaccumulate Cd) is considered as a model species for the study of metal homeostasis and detoxification. This review will summarize our knowledge about Cd tolerance and accumulation acquired in A. halleri and how this knowledge may be used in phytoextraction.
