Production of progenitor cereal cells

(canceled)

3:

• The process according to claim 2, wherein the progenitor cells are multiplied at a greater rate than non-progenitor cells.

4:

• The process according to claim 1, wherein the undifferentiated cereal callus cells are selected from the group of cereals consisting of sorghum, maize, wheat, barley, millet, rye, canola, alfalfa, triticale and rice.

5:

• The process according to claim 1, wherein the cytokinin is selected from the group consisting of benzyl amino purine, benzyladenine, thidiazuron, zeatin, isopentyladenine, trans-zeatin and dimethylallyladenine.

6:

• The process according to claim 1, wherein the auxin is selected from the group consisting of 2,4-dichlorophenoxyacetic acid, indole-3-acetic acid, picloran, naphthelenacetic acid, indole-3-propionic acid, indole-3-butyric acid, phenyl acetic acid, benzofuran-3-acetic acid and phenyl butyric acid.

7-8. (canceled)

9:

• The process according to claim 1, wherein the pluripotent and/or totipotent progenitor cereal cells organize into cell aggregates to form shoot apical meristematic domes and primordial shoots by a process of direct organogenesis.

10:

• The process according to claim 1, wherein the undifferentiated cereal callus cells are obtained from plant tissue that has been transformed with an homologous or heterologous gene.

(canceled)

12:

• The process according to claim 10, wherein the transformation step is Agrobacterium-mediated.

13:

• The process according to claim 10, wherein the transformation step is via biolistic bombardment.

14:

• The process according to claim 1, wherein the pluripotent and/or totipotent progenitor cereal cells are maintained in a state of perpetual proliferation.

15-16. (canceled)

17:

• The process according to claim 16, wherein the secondary plant tissue culture medium includes at least one cytokinin and/or at least one auxin.

(canceled)

19:

• The process according to claim 10, wherein the transformation frequency of the process is at least 5%, at least 10%, at least 15%, at least 19%, at least 20% or at least 30%.

20-24. (canceled)

25:

• The process according to claim 1, wherein the undifferentiated cereal callus cells are from scutellum tissue from an embryo.

32:

• Transformed progenitor cells produced by the process of claim 31.

33:

• A transgenic plant part, plantlet or plant obtained from pluripotent and/or totipotent progenitor cereal cells produced by the process of claim 10.
