Patents granted to Schilperoort & Hille
Two patents granted to Schilperoort & Hille are related to transformation of dicotyledonous (dicot) plants using stable co-integrated plasmids. The granted patents were obtained in Europe (EP) and in the United States of America (US). The European patent was assigned to the University of Leiden and Prof. Dr. R. Schilperoort.
In general, both patents disclose transformation of dicot plant protoplasts by infecting them with an A. tumefaciens strain containing a stable co-integrated plasmid. The co-integrated plasmid results from the combination of the Ti plasmid pTiB6 and the broad host range plasmid R772. In the European patent, the A. tumefaciens strain used for plant transformation contains a plasmid derived from the co-integrated plasmid pAL969, which has a T-region from pTiB6 and contains only foreign DNA between the border sequences.
