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.

Abstract

Pollution by heavy metals is one of the strongest environmental constraints in human-altered environments that only a handful of species can cope with. Identifying the genes conferring to those species the ability to grow in polluted areas is a first step towards a global understanding of the evolutionary processes involved and will eventually improve phytoremediation practices. We used a genome-scan approach to detect loci under divergent selection among four populations of Arabidopsis halleri growing on either polluted or nonpolluted habitats. Based on a high density of amplified fragment length polymorphism (AFLP) markers (820 AFLP markers, i.e. ~1 marker per 0.3 Mb), evidence for selection was found for some markers in every sampled population. Four loci departed from neutrality in both metallicolous populations and thus constitute high-quality candidates for general adaptation to pollution. Interestingly, some candidates differed between the two metallicolous populations, suggesting the possibility that different loci may be involved in adaptation in the different metallicolous populations.

Abstract

The article discusses the cadmium tolerance and accumulation in the hyperacccumulators including Noccaea caerulescens and Arabidopsis halleri, the later seemed to show more tolerance towards Cd and a cross between A. halleri and a non tolerant relative was found with additional genes.
