Genetic variability of Colobanthus quitensis from King George Island (Antarctica)
Antarctic pearlwort (Colobanthus quitensis) is one of the flowering plant species considered native to maritime Antarctica. Although the species was intensively analyzed towards its morphological, anatomical and physiological adaptation to local environment, its genetic variability is still poorly s...
