Abstract

The present invention relates to a transgenic plant which integrated into its genome an exogenous polynucleotide encoding a polypeptide which confers resistance to one or more races of Puccinia graminis f. sp. tritici , such as the Ug99 group of races Puccinia graminis f. sp. tritici.

First claim

The invention claimed is:

1. A plant genetically modified to comprise a gene encoding a polypeptide which is at least 99% identical to SEQ ID NO:1, wherein the polypeptide confers resistance to one or more races of Puccinia graminis , and wherein the plant is a cereal plant.

2. The plant of claim 1 , wherein the Puccinia graminis is Puccinia graminis f. sp. tritici.

3. The plant of claim 2 , wherein the Puccinia graminis f. sp. tritici is a race of the Ug99 group.

4. The plant of claim 1 which has enhanced resistance to Puccinia graminis when compared to an isogenic plant lacking the gene encoding the polypeptide.

5. The plant of claim 1 which comprises one or more further exogenous polynucleotides encoding another plant pathogen resistance polypeptide.

6. The plant of claim 1 which is homozygous for the gene encoding the polypeptide.

7. A seed of a plant of claim 1 comprising the gene encoding the polypeptide.

8. The plant of claim 1 , wherein the polypeptide comprises the amino acid sequence of SEQ ID NO: 1.

9. The plant of claim 1 , wherein the polypeptide is encoded by the nucleic acid having the polynucleotide sequence of SEQ ID NO: 10.

10. The plant of claim 1 , wherein the polypeptide is encoded by a nucleic acid having a polynucleotide sequence which is at least 99% identical to SEQ ID NO:10.

11. The plant of claim 1 , wherein the cereal plant is a wheat plant.

12. The plant of claim 1 , wherein the polypeptide comprises a coiled coil (CC) domain, a nucleotide binding (NB) domain and a leucine rich repeat (LRR) domain.

13. The plant of claim 1 , wherein the cereal plant is a rye plant.
