Patents and application assigned to Japan Tobacco-Patents and application assigned to Japan Tobacco

This family of patents and one application disclose the use of an immature embryo of a monocot for Agrobacterium-mediated transformation. Within the embryo, the tissue to be transformed is the scutellum, which is the name given to the cotyledon of monocot plants. The transformed scutellum can be induced to become dedifferentiated calli that have the ability to regenerate normal plants after transformation.

In addition, they disclose an Agrobacterium used for transformation that contains a Ti or Ri (root-inducing) plasmid with a desired gene and a plasmid having a virulence region derived from the A. tumefaciens Ti plasmid pTiBo542.
