The perennial Arabidopsis lyrata is able to propagate both sexually and asexually, and this is expected to influence spatial genetic structure in the species. A fine-scale molecular study by Lundemo et al. (pp. 243–254) shows how a large, alpine population in Norway overall functions as a panmictic unit, while at the same time individual plants in smaller patches exhibit considerable clonal growth.
