What is claimed is: 1. A method of increasing the level of nitrogen in a plant, said method comprising transforming a plant cell with an exogenous nucleic acid comprising a nucleotide sequence encoding a polypeptide having 95% percent or greater sequence identity to the amino acid sequence set fort
What is claimed is: 1. A method of increasing the level of nitrogen in a plant, said method comprising transforming a plant cell with an exogenous nucleic acid comprising a nucleotide sequence encoding a polypeptide having 95% percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:2, and regenerating said plant from said transformed plant cell, wherein expression of said nucleotide sequence increases the level of nitrogen in said transformed plant as compared to the level of nitrogen in a control plant of the same species which is not transformed with said exogenous nucleic acid. 2. The method of claim 1, wherein said exogenous nucleic acid is operably linked to a regulatory region. 3. The method of claim 2, wherein said regulatory region is a promoter selected from the group consisting of YP0092 having SEQ ID NO:55, PT0672 having SEQ ID NO:57, PT0837 having SEQ ID NO:56, a napin promoter, an Arcelin-5 promoter, a phaseolin gene promoter, a soybean trypsin inhibitor promoter, an ACP promoter, a stearoyl-ACP desaturase gene promoter, a soybean subunit of β-conglycinin promoter, an oleosin promoter, a 15 kD zein promoter, a 16 kD zein promoter, a 19 kD zein promoter, a 22 kD zein promoter, a 27 kD zein promoter, an Osgt-1 (Oryza sativa glutelin-1) promoter, a beta-amylase gene promoter, and a barley hordein gene promoter. 4. A method of producing a plant tissue, said method comprising growing a plant comprising an exogenous nucleic acid comprising a nucleotide sequence encoding a polypeptide having 95% percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:2, wherein said plant expressing said nucleotide sequence has an increased level of nitrogen as compared to the level of nitrogen in a control plant of the same species which lacks said exogenous nucleic acid; and obtaining tissue from said plant. 5. A transformed plant cell comprising an exogenous nucleic acid comprising a nucleotide sequence encoding a polypeptide having 95% percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:2, wherein expression of the nucleotide sequence increases the level of nitrogen in the transformed plant cell as compared to the level of nitrogen of a cell of a control plant of the same species which is not transformed with said exogenous nucleic acid. 6. A transgenic plant comprising the plant cell of claim 5. 7. A progeny of the plant of claim 6, wherein said progeny expressing said nucleotide sequence has an increased level of nitrogen as compared to the level of nitrogen in a control plant of the same species which is not transformed with said exogenous nucleic acid. 8. A seed from the transgenic plant according to claim 6, wherein said seed comprises said nucleic acid. 9. A vegetative tissue from the transgenic plant according to claim 6; wherein said vegetative tissue comprises said nucleic acid. 10. The method of claim 1, wherein said nucleotide sequence encodes a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:2. 11. The method of claim 1, wherein said plant is a member of the genus Brassica, Glycine, Gossypium, Oryza, Panicum, or Zea. 12. The method of claim 4, wherein said nucleotide sequence encodes a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:2. 13. The method of claim 4, wherein said plant tissue is a member of the genus Brassica, Glycine, Gossypium, Oryza, Panicum, or Zea. 14. The method of claim 5, wherein said nucleotide sequence encodes a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:2. 15. The method of claim 5, wherein said plant is a member of the genus Brassica, Glycine, Gossypium, Oryza, Panicum, or Zea.
