Regulatory polynucleotides and uses thereof
The present disclosure provides compositions and methods for regulating expression of transcribable polynucleotides in plant cells, plant tissues, and plants. Compositions include regulatory polynucleotide molecules capable of providing expression in plant tissues and plants. Methods for expressing polynucleotides in a plant cell, plant tissue, or plants using the regulatory polynucleotide molecules disclosed herein are also provided.
1. A recombinant polynucleotide molecule comprising a regulatory polynucleotide sequence selected from the group consisting of:
(a) the sequence of nucleotides 858-1205 of SEQ ID NO: 9; and
(b) a sequence having at least 99% sequence identity to nucleotides 858-1205 of SEQ ID NO: 9;
wherein said regulatory polynucleotide sequence is operably linked to a heterologous promoter sequence; and wherein said regulatory polynucleotide sequence is operably linked to a heterologous transcribable polynucleotide molecule.
2. The recombinant polynucleotide molecule of claim 1 , wherein the regulatory polynucleotide sequence comprises the sequence of nucleotides 858-1205 of SEQ ID NO: 9.
3. The recombinant polynucleotide molecule of claim 1 , wherein the transcribable polynucleotide molecule encodes a protein of agronomic interest or a functional RNA.
4. The recombinant polynucleotide molecule of claim 3 , wherein the protein of agronomic interest confers herbicide tolerance to plants.
5. The recombinant polynucleotide molecule of claim 3 , wherein the protein of agronomic interest confers pest resistance to plants.
6. A transgenic host cell comprising the recombinant polynucleotide molecule of claim 1 .
7. The transgenic host cell of claim 6 , wherein the host cell is a plant cell.
8. A transgenic plant stably transformed with the recombinant polynucleotide molecule of claim 1 .
9. The transgenic plant of claim 8 , wherein the plant is selected from the group consisting of: a monocotyledonous and a dicotyledonous plant.
10. The transgenic plant of claim 9 , wherein the plant is a monocotyledonous plant selected from the group consisting of: wheat, corn, rice, turf grass, millet, sorghum, switchgrass, miscanthus, sugarcane, and Brachypodium.
11. The transgenic plant of claim 9 , wherein the plant is a dicotyledonous plant selected from the group consisting of: soybean, cotton, canola, and potato.
12. A seed produced by the transgenic plant of claim 8 wherein said seed comprises said recombinant polynucleotide molecule.
13. A method of directing expression of a transcribable polynucleotide molecule in a host cell comprising:
(a) introducing the recombinant polynucleotide molecule of claim 1 into a host cell to produce a transgenic host cell; and
(b) selecting a transgenic host cell exhibiting expression of the transcribable polynucleotide molecule.
14. The method of claim 13 , wherein the host cell is a plant cell.
15. The method of claim 14 further comprising regenerating a plant from the selected transgenic plant cell.
