Floral transition genes in maize and uses thereof
The invention provides isolated floral transition nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering floral transition in plants. The invention further provides regulatory elements, recombinant expression cassettes, host cells, and transgenic plants.
1. An isolated polynucleotide that functions as a promoter comprising the nucleotide sequence set forth in SEQ ID NO:29.
2. A recombinant expression cassette comprising the polynucleotide of claim 1 .
3. An isolated host cell comprising the polynucleotide of claim 1 .
4. A transgenic plant comprising the polynucleotide of claim 1 .
5. The transgenic plant of claim 4 , wherein said plant is a monocot.
6. The transgenic plant of claim 4 , wherein said plant is a dicot.
7. The transgenic plant of claim 4 , wherein said plant is selected from the group consisting of: maize, soybean, sunflower, sorghum, canola, wheat, alfalfa, cotton, rice, barley, millet, peanut and cocoa.
8. A transgenic seed from the transgenic plant of claim 4 wherein the seed comprises said polynucleotide.
9. A method of modulating the flowering time in a plant, comprising:
a. introducing into a plant cell a recombinant expression cassette comprising the polynucleotide of claim 1 operably linked to a nucleic acid encoding a polypeptide involved in flowering time; and
b. culturing a plant under plant cell growing conditions; wherein the flowering time in said plant is modulated.
10. The method of claim 9 , wherein the plant cell is from a plant selected from the group consisting of: maize, soybean, sunflower, sorghum, canola, wheat, alfalfa, cotton, rice, barley, millet, peanut and cocoa.
11. The method of claim 9 , further comprising crossing said plant with another plant to produce hybrid seed.
