Agrobacterium has been established as a tool for gene delivery to most dicotyledonous plant species. However, it is not generally efficient in monocotyledonous plant species, especially not in Graminae. In maize, Agrobacterium-mediated DNA transfer has been detected but early developmental stages in the plant proved incompetent as recipients. This research tests whether the lack of competence in young immature embryos of maize could be overcome by providing Agrobacterium in the interior of the plant cell. A microinjection technique was used to target single meristematic cells and prove competence to Agrobacterium. This response is dependent on the maize plant genotype.
