The metal hyperaccumulator Arabidopsis halleri exhibits naturally selected zinc (Zn) and
cadmium (Cd) hypertolerance and accumulates extraordinarily high Zn concentrations in its …

Arabidopsis halleri ssp. halleri (accession Langelsheim) is a naturally selected zinc (Zn)‐
and cadmium‐tolerant Zn hyperaccumulator. This plant differs strikingly from its close …

Identifying the particular gene or genes underlying a specific adaptation is a major
challenge in modern biology. Currently, the study of naturally occurring variation in …

Plants have the ability to colonize highly diverse environments. The zinc and cadmium
hyperaccumulator Arabidopsis halleri has adapted to establish populations on soils …

Zinc (Zn) and cadmium (Cd) hyperaccumulation may have evolved twice in the
Brassicaceae, in Arabidopsis halleri and in the Noccaea genus. Tandem gene duplication …

Gene duplication is a major mechanism facilitating adaptation to changing environments.
From recent genomic analyses, the acquisition of zinc hypertolerance and …

In the course of evolution, plants adapted to widely differing metal availabilities in soils and
therefore represent an important source of natural variation of metal homeostasis networks …

To survive in variable soil conditions, plants possess homeostatic mechanisms to maintain a
suitable concentration of essential heavy metal ions. Certain plants, inhabiting heavy metal …

Metal hyperaccumulation is a trait present in over 450 higher plant species.
Hyperaccumulators are also tolerant to metals, but hyperaccumulation and tolerance are …

Arabidopsis halleri is a model species for the study of plant adaptation to extreme metallic
conditions. In this species, cadmium (Cd) tolerance seems to be constitutive, and the …
