Claims
- 1. An isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and a nucleotide sequence coding region for a virus coat protein which confers virus resistance.
- 2. An isolated DNA molecule as claimed in claim 1, wherein the nucleotide coding region for the virus coat protein which confers virus resistance is obtained by cDNA cloning starting from RNA of cucumber mosaic virus, alfalfa mosaic virus or brome mosaic virus.
- 3. An isolated DNA molecule as claimed in any one of claims 1 or 2 wherein the nucleotide coding region for the phosphinothricin acetyl transferase protein is from Streptomyces.
- 4. A host cell containing an isolated DNA molecule as claimed in claim 3, which expresses the proteins.
- 5. A host cell containing an isolated DNA molecule as claimed in any one of claims 1 or 2, which expresses the proteins.
- 6. Plants, plant cells, or seeds of plants containing the isolated DNA molecule as claimed in any of claims 1 or 2, and which express the proteins.
- 7. Plants, plant cells, or seeds of plants containing the isolated DNA molecule of claim 3, and which express the proteins.
- 8. A host cell containing the isolated DNA molecule of claim 2, wherein the nucleotide coding region for the phosphinothricin acetyl transferase protein is from Streptomyces and the cell expresses the proteins.
- 9. Plants, plant cells or plant seeds containing the cell of claim 8.
- 10. A transformed plant cell containing and expressing an isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and, an isolated DNA molecule consisting of a nucleotide sequence coding region for a virus coat protein which confers virus resistance.
- 11. A method for improving growth of a plant comprising: transforming plant cells so that the cells contain an isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and, an isolated DNA molecule consisting of a nucleotide sequence coding region for a virus coat protein which confers virus resistance; selecting transformed cells; regenerating plants from the cells; and treating the regenerated plants with a phosphinothricin herbicide.
- 12. The cell of claim 10 wherein the virus is cucumber, alfalfa or brome mosaic virus.
- 13. The cell of claims 10, or 12 wherein the isolated DNA molecule consisting of a nucleotide sequence coding region for the phosphinothricin acetyl transferase protein is from Streptomyces.
- 14. A method for improving growth of a plant comprising regenerating the plant from the cell as claimed in claims 10, or 12 and treating the regenerated plant with a phosphinothricin herbicide.
- 15. A method for improving grouch of a plant comprising regenerating the plant from the cell of claim 13, and treating the regenerated plant with a phosphinothricin herbicide.
- 16. The method of claim 11 wherein the virus is cucumber, alfalfa or brome mosaic virus.
- 17. The method of claims 11, or 16 wherein the coding region for the phosphinothricin acetyl transferase protein is from Streptomyces.
- 18. A plant, or plant seed containing the cell of claim 10, or 12.
- 19. A plant, or plant seed containing the cell of claim 13.
