Abstract

This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum , which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum , and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.

Claims (26)

1. Seed of corn variety designated DE811ASR(BC5), a representative sample of which has been deposited as ATCC accession number PTA-7434.

2. A plant produced from the seed of claim 1 .

3. A plant cell of the plant of claim 2 .

4. A method of producing hybrid seed comprising crossing the plant of claim 2 with a different corn plant, and harvesting the resultant seed.

5. The method of claim 4 in which the resultant seed produces a plant that exhibits resistance to Colletotrichum infection.

6. The method of claim 4 in which the different corn plant is a plant of an inbred line.

7. The method of claim 6 in which the resultant seed produces a plant that exhibits resistance to Colletotrichum infection.

8. A corn plant produced by the method of claim 5 .

9. A corn plant produced by the method of claim 7 .

10. An F1 hybrid corn seed produced by crossing a corn plant designated DE811ASR(BC5), a representative seed of which has been deposited as ATCC accession number PTA-7434, with a different corn plant, and harvesting the resultant F1 hybrid corn seed.

11. The seed of claim 10 , wherein a corn plant grown from the seed exhibits resistance to Colletotrichum infection.

12. A corn plant produced by the seed of claim 10 .

13. A plant cell of the plant of claim 12 .

14. A component of the plant of claim 12 ; wherein the component is an embryo, pollen, ovule, leaf, flower, branch, fruit, kernel, ear, cob, husk, stalk, root, root tip, or anther.

15. A callus produced from the plant of claim 12 .

16. A protoplast produced from the plant cell of claim 13 .

17. A method for producing a corn plant, comprising:

(a) crossing a corn plant designated DE811ASR(BC5), a representative seed of which has been deposited as ATCC accession number PTA-7434, with a different corn plant to produce a progeny corn plant;

(b) crossing the progeny corn plant with itself or a different corn plant to produce a progeny corn plant of a subsequent generation; and,

(c) crossing the progeny corn plant of a subsequent generation with itself or a different corn plant to produce a corn plant derived from the corn variety DE811ASR(BC5).

18. The method of claim 17 , optionally comprising repeating steps (b) and (c) at least once.

19. A component of the plant of claim 2 ; wherein the component is an embryo, pollen, ovule, leaf, flower, branch, fruit, kernel, ear, cob, husk, stalk, root, root tip, or anther.

20. A callus produced from the plant of claim 2 .

21. A protoplast produced from the plant cell of claim 3 .

22. A component of the plant of claim 2 ;

wherein the component is an embryo, pollen, ovule, leaf, flower, branch, fruit, kernel, ear, cob, husk, stalk, root, root tip, or anther.
