Grape vine DNA research. Professor Massimo Labra from the University of Milan preparing to analyse the DNA from a sample of the Grenache grape variety (Vitis sp.), using a sequencing cell. The cell is a Biorad Sequigen GT nucleic acid electrophoresis cell (for DNA sequencing and fingerprinting) and was used 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.
