Patent granted to Nunhems Zaden BV
The present United States patent granted to Nunhems Zaden from Holland discloses a process to obtain transgenic plants by using Agrobacterium mutants deficient in the biosynthesis of specified vital biomolecules. This allows a controlled systemic infection of the tissues to be transformed to be maintained for longer periods, thereby increasing the probability of successful infection. The Agrobacterium can then be eliminated by omission of those nutrients from the incubation medium.
