Transcription regulating nucleotide sequences and methods of use
Described herein are nucleic acid having constitutive promoter activities and the use of such nucleic acid having constitutive promoter activities to express a polynucleotide of interest in plants.
1. A recombinant gene for regulating expression of a polynucleotide of interest, said recombinant gene comprising a heterologous nucleic acid having constitutive promoter activity comprising the nucleotide sequence of SEQ ID NO: 1 or SEQ ID NO: 2.
2. The recombinant gene of claim 1 , wherein said recombinant gene further comprises at least one polynucleotide of interest being operatively linked to the nucleic acid having constitutive promoter activity.
3. The recombinant gene of claim 1 , wherein the polynucleotide of interest encodes an insecticidal protein or a herbicide selectable marker.
4. A vector comprising the recombinant gene according to claim 1 .
5. The vector of claim 4 , wherein said vector is an expression vector.
6. A host cell comprising a heterologous nucleic acid having constitutive promoter activity
comprising the nucleotide sequence of SEQ ID NO: 1 or SEQ ID NO: 2.
7. The host cell of claim 6 , wherein said host cell is a plant cell.
8. A plant, plant part or seed comprising a heterologous nucleic acid having constitutive promoter activity
comprising the nucleotide sequence of SEQ ID NO: 1 or SEQ ID NO: 2.
9. A method for expressing a polynucleotide of interest in a host cell comprising
(a) introducing the recombinant gene according to claim 1 into said host cell, and
(b) expressing at least one polynucleotide of interest in said host cell.
10. The method of claim 9 , wherein said host cell is a plant cell.
11. The method of claim 9 , wherein the polynucleotide of interest encodes a protein that accumulates to a detectable amount of about 0.01%-1.15% of the extracted total soluble proteins.
12. A method for producing a plant or plant part comprising
(a) introducing the recombinant gene according to claim 1 into a plant cell; and
(b) regenerating said plant cell to form a plant or plant part.
13. A method of providing pesticidal activity in a plant comprising
(a) introducing the recombinant gene according to claim 1 into a host cell, and
(b) expressing a polynucleotide that encodes a pesticidal protein in said host cell, thereby providing pesticidal activity in the plant.
14. The method of claim 13 , wherein the pesticidal protein is an insecticidal protein.
15. A method of producing food, feed, or an industrial product comprising
a) obtaining the plant, plant part or seed, of claim 8 ; and
b) preparing the food, feed or industrial product from the plant, plant part or seed.
16. The method of claim 15 wherein
a) the food or feed is oil, meal, grain, starch, flour or protein; or
b) the industrial product is biofuel, fiber, industrial chemicals, a pharmaceutical or a nutraceutical.
