Historical biogeography and expansion of Lactuca serriola: Analysis of geneflow from crop to wild forms in lettuce (Lactuca serriola) and chicory (Cichorium intybus) and its population-ecological consequences in the context of GM-crop biosafety. Biogeographical analysis, addresses the background of L. serriola’s recent invasiveness into Northwestern Europe by an analysis of the distribution shift and genetic variation on a transect from south to north and from east to west through Europe using microsatellites (SSR). Collaboration with the University of Neuchâtel and EU.
