Abstract

In natural populations of Arabidobsis thaliana (L.) Heynh., occupying northern limits of the species range (Karelia), the level of genetic diversity was evaluated. In two insular and one mainland population variability at 82 RAPD loci was tested. Considerable genetic diversity revealed (P = 4.5%; H exp = 0.177) was not typical of self-pollinating plant species. It was demonstrated that genetic differentiation among the populations (G ST = 0.680) was rather high, pointing to the low level of gene flow in the isolated insular populations. It was suggested that the high level of Arabidopsis population polymorphism in Karelia could be associated with extreme growing conditions at the northern limits of the species range.
