Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20080127375, Methods of protecting plants from pathogenic fungi.

1. A method for enhancing resistance of a plant to a pathogen, said method comprising: (a) stably transforming a plant cell with at least one expression cassette comprising a nucleotide sequence operably linked to a promoter that drives expression in a cell of said plant, wherein said nucleotide sequence has at least 95% sequence identity to SEQ ID NO: 15, and further wherein said nucleotide sequence encodes a polypeptide having activity against at least one plant fungal pathogen; and (b) regenerating a transformed plant from said plant cell, wherein the level of resistance to said fungal pathogen in said plant is increased in comparison to a plant that does not comprise said expression cassette.

2. The method of claim 1, wherein the promoter is selected from the group consisting of: a) a constitutive promoter; b) a tissue-specific promoter; and c) an inducible promoter.

3. The method of claim 1, wherein the polypeptide further comprises a heterologous signal sequence.

4. The method of claim 3, wherein the signal sequence is a secretion signal sequence.

5. The method of claim 3, wherein the signal sequence is an organelle signal sequence.

6. The method of claim 3, wherein the signal sequence is a plastid signal sequence.

7. The method of claim 1, wherein the nucleotide sequence is SEQ ID NO: 15.

8. A transgenic plant having stably incorporated into its genome a polynucleotide sequence at least 95% identical to SEQ ID NO: 15, wherein said polynucleotide sequence encodes a polypeptide with activity against plant fungal pathogens, further wherein said plant has improved fungal pathogen resistance to at least one plant pathogenic fungus.

9. The plant according to claim 8, wherein said plant is a monocot.

10. The plant according to claim 8, wherein said plant is a dicot.

11. Transformed seed of the plant of claim 8, wherein the seed comprise the polynucleotide sequence.

12. The plant according to claim 8, wherein said polynucleotide is operably linked to a promoter that drives expression in a cell of said plant, wherein said promoter is selected from the group consisting of: a) a constitutive promoter; b) a tissue-specific promoter; and c) an inducible promoter.

13. The plant according to claim 8, wherein the polypeptide further comprises a heterologous signal sequence.

14. The plant according to claim 13, wherein the signal sequence is a secretion signal sequence.

15. The plant according to claim 13, wherein the signal sequence is an organelle signal sequence.

16. The plant according to claim 13, wherein the signal sequence is a plastid signal sequence.

17. The plant according to claim 8, wherein said polynucleotide sequence is SEQ ID NO: 15.

18. The method of claim 2, wherein the tissue-specific promoter is a root-specific promoter, and the inducible promoter is a pathogen-inducible promoter.

19. The plant of claim 12, wherein the tissue-specific promoter is a root-specific promoter, and the inducible promoter is a pathogen-inducible promoter.
