The genome of Draba nivalis shows signatures of adaptation to the extreme environmental stresses of the Arctic ...
The Arctic is one of the most extreme terrestrial environments on the planet. Here we present the first complete genome assembly of a plant adapted to the high Arctic, Draba nivalis (Brassicaceae), an attractive model species for studying plant adaptation to the stresses imposed by this harsh enviro...
