Promoter, promoter control elements, and combinations, and uses thereof
The present invention is directed to promoter sequences and promoter control elements, polynucleotide constructs comprising the promoters and control elements, and methods of identifying the promoters, control elements, or fragments thereof. The invention further relates to the use of the present promoters or promoter control elements to modulate transcript levels.
1. An isolated nucleic acid molecule that modulates transcription, wherein the nucleic acid molecule is SEQ ID NO:6 or a fragment thereof having promoter activity.
2. The isolated nucleic acid molecule of claim 1 , wherein said nucleic acid functions as a promoter.
3. The isolated nucleic acid molecule of claim 1 , wherein said nucleic acid molecule modulates transcription during particular developmental times or in response to a stimuli or in a particular cell, tissue, or organ as set forth in the Sequence Listing-Miscellaneous Feature.
4. A vector construct comprising:
a) a first nucleic acid that modulates transcription wherein the nucleic acid molecule is SEQ ID NO:6 or a fragment thereof having promoter activity; and
b) a second nucleic acid having to be transcribed,
wherein said first and second nucleic acid molecules are heterologous to each other and are operably linked together.
5. A host cell comprising an isolated nucleic acid molecule according to claim 1 , wherein said nucleic acid molecule is flanked by exogenous sequence.
6. A host cell comprising a vector construct of claim 4 .
7. A method of modulating transcription by combining, in an environment suitable for transcription:
a) a first nucleic acid molecule that modulates transcription wherein the nucleic acid molecule is SEQ ID NO:6 or a fragment thereof having promoter activity; and
b) a second molecule to be transcribed;
wherein the first and second nucleic acid molecules are heterologous to each other and operably linked together.
8. The method according to claim 7 , wherein said first nucleic acid molecule modulates transcription during the particular developmental times or in response to a stimuli or in a particular cell tissue, or organ as set forth in the Sequence Listing-Miscellaneous Feature wherein said first nucleic acid molecule is inserted into a plant cell and said plant cell is regenerated into a plant.
9. A plant comprising a vector construct according to claim 4 .
