Description
Summary:Using DNA markers and sequencing we investigated patterns of genetic variability in purple saxifrage, Saxifraga oppositifolia in the isolated Arctic Svalbard archipelago. Purple saxifrage is a circumpolar, ecologically and morphologically variable species with a wide range of habitats. Population genetic structures showed that both genetic variation and differentiation levels are modest, outcrossing is the main mating system, and dispersal and gene flow are important, likely accountable to strong winds and human and animal vectors. Different growth habits (compact, trailing and intermediate) did not possess distinct genetic composition.
