Arabidopsis arenosa is a model species for autotetraploidy studies and is often found in heavy metal-contaminated sites alongside the hyperaccumulator plant A. halleri. Several populations of A. arenosa also exhibit hyperaccumulation of Cd and Zn, although the mechanism differs from that of A. halleri. Further research is needed to fully understand this phenomenon.
The following review article collects information on the plant species Arabidopsis arenosa. Thus far, A. arenosa has been known as a model species for autotetraploidy studies because, apart from diploid individuals, there are also tetraploid populations, which is a unique feature of this Arabidopsis species. In addition, A arenosa has often been reported in heavy metal-contaminated sites, where it occurs together with a closely related species A. halleri, a model plant hyperaccumulator of Cd and Zn. Recent studies have shown that several populations of A. arenosa also exhibit Cd and Zn hyperaccumulation. However, it is assumed that the mechanism of hyperaccumulation differs between these two Arabidopsis species. Nevertheless, this phenomenon is still not fully understood, and thorough research is needed. In this paper, we summarize the current state of knowledge regarding research on A. arenosa.
