Arabidopsis arenosa

About

Arabidopsis arenosa, the sand rock-cress, is a species of flowering plant in the family Brassicaceae. It is found mostly in Central Europe in both a diploid and an autotetraploid form. This sets it apart from the other, mostly diploid, Arabidopsis species including the closely related Arabidopsis lyrata or Arabidopsis thaliana, the model plant species.
