Grape vine DNA research. Rack of vials containing the DNA from samples of Grenache (Vitis sp.), a grape variety grown primarily for the production of red wine. This formed part of a study where the DNA extracted from different vine samples was analysed to help determine the geographical origin of the vines. Genetic analyses from more than 500 sites revealed that vines do not only have one single origin, as was thought, but several origins around the circumference of the Mediterranean Basin.
