Title:	Nuclear fertility restorer genes and methods of use in plants
Abstract:	The present invention includes nuclear fertility restorer genes, proteins encoded by those genes and transgenic plants and plant cells containing those genes. More particularly, the nuclear fertility restorer genes can be used to restore fertility in cytoplasmic male-sterile plants such as Brassica napus. Preferably, the nuclear fertility restorer genes are used with the Ogura (ogu) CMS system in Brassica napus.

Application Number:	10/345,072
Patent Claims:	1. A method of identifying a transformed Brassica plant, comprising the steps of: a) providing an expression cassette comprising a radish genomic DNA that encodes a male fertility restorer protein having a sequence comprising amino acids 1 to 687 of SEQ ID NO:179; b) introducing said expression cassette into cells of a cytoplasmically male sterile Brassica plant; c) regenerating Brassica plants from said cells; and d) identifying a Brassica plant from step c) that forms seeds by self-pollination, thereby identifying the transformed Brassica plant. 2. The method of claim 1, wherein said plant is Brassica napus. 3. The method of claim 1, wherein said expression cassette is covalently linked to a sequence of interest. 4. The method of claim 1, wherein said expression cassette is cotransformed into said plant cells with a sequence of interest. 5. A method of identifying a transformed Brassica plant, comprising the steps of: a) providing an expression cassette comprising a radish genomic DNA that encodes a male fertility restorer protein having a sequence comprising amino acids 1 to 687 of SEQ ID NO:179; b) introducing said expression cassette into cytoplasmically male sterile Brassica plants; and c) identifying a Brassica plant from step b) that forms seeds when self-pollinated, thereby identifying the transformed Brassica plant. 6. The method of claim 5, wherein said plant is Brassica napus. 7. The method of claim 5, wherein said expression cassette is covalently linked to a sequence of interest. 8. The method of claim 5, wherein said expression cassette is cotransformed into said plant cells with a sequence of interest. 9. An isolated nucleic acid selected from the group consisting of: a) an open reading frame encoding an Rfo protein, said open reading frame being contained within genomic DNA having a sequence comprising nucleotides 167,079 to 173,669 of SEQ ID NO:87, wherein nucleotides 167,459 to 167,585 represent an intron; b) a full-length complement of a) and c) a nucleic acid comprising a nucleotide sequence differing from the sequence of the nucleic acids of a) or b) due to the degeneracy of the genetic code. 10. The nucleic acid of claim 9, wherein the open reading frame encodes the Rfo protein having a sequence comprising amino acids 1 to 687 of SEQ ID NO:179. 11. An isolated radish genomic nucleic acid comprising a gene encoding a protein having a sequence comprising amino acids 1 to 687 of SEQ ID NO:179. 12. An isolated nucleic acid comprising nucleotides 164,311 to 174,022 of SEQ ID NO:87. 13. The full-length complement of the nucleic acid of claim 12. 14. A Brassica plant transformed with an isolated nucleic acid selected from the group consisting of: a) an open reading frame encoding an Rfo protein, said open reading frame being contained within genomic DNA having a sequence comprising nucleotides 167,079 to 173,669 of SEQ ID NO:87, wherein nucleotides 167,459 to 167,585 represent an intron; b) a full-length complement of a); and c) a nucleic acid comprising a nucleotide sequence differing from the sequence of the nucleic acids of a) or b) due to degeneracy of the genetic code. 15. The plant of claim 14, wherein the nucleic acid is an open reading frame contained within the genomic DNA having the sequence comprising nucleotides 167,079 to 173,669 of SEQ ID NO:87, and wherein nucleotides 167,459 to 167,585 represent an intron. 16. The plant of claim 14, wherein the nucleic acid encodes a protein having a sequence comprising amino acids 1 to 687 of SEQ ID NO:179. 17. The plant of claim 14, wherein the nucleic acid is the full-length complement of the open reading frame contained within the genomic DNA having the sequence comprising nucleotides 167,079 to 173,669 of SEQ ID NO:87, and wherein nucleotides 167,459 to 167,585 represent an intron. 18. A Brassica plant transformed with an expression vector comprising an isolated nucleic acid having a sequence comprising nucleotides 164,311 to 174,022 of SEQ ID NO:87.
