In 2001 Monsanto was granted an Australian patent directed to transformation of wheat with Agrobacterium. Related applications are still pending in Europe and Canada.
The granted claims of the Australian patent are narrower in their scope than the claims as filed in the European and Canadian applications. In the Australian patent the wheat tissues to be transformed are restricted to certain types of tissues while the applications disclose the transformation of wheat cells derived from any tissue.
Both the Australian patent and the applications disclose the insertion into the cells of genes that confer resistance to selective agents such as gentamycin, kanamycin, and hygromycin. Production of fertile and transgenic wheat plants is also disclosed.
Note that the claim language may be modified during the prosecution process and when granted might not encompass the same scope as the filed claims.

|AU 738153 C
||Title – Methods for the production of stably-transformed, fertile wheat employing agrobacterium-mediated transformation and compositions derived therefrom
Process for the production of a fertile, transgenic wheat plant by transforming an immature embryo, a callus tissue or suspension cells of wheat with Agrobacterium having an exogenous gene.
|EP 856060 A1
||Title – Methods for the Production of Stably-transformed, Fertile Wheat employing Agrobacterium-mediated transformation and compositions derived therefrom
National phase entry of WO 97/48814, this application is still pending.
Insertion of a foreign gene into a wheat plant via Agrobacterium . The foreign gene is selected from a group of genes conferring resistance to different antibiotics, i.e. kanamycin, hygromycin, and also the GUS gene. Regenerating and obtaining fertile transformed wheat plants is also covered by the claims.
