Viral promoter, truncations thereof, and methods of use
View Patent ↗The present disclosure provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a promoter. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequence disclosed herein is provided. The method comprises stably incorporating into the genome of a plant cell a nucleotide sequence operably linked to the promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence.
1. An isolated nucleic acid molecule comprising a nucleotide sequence that initiates transcription in a plant cell, wherein said nucleotide sequence is the sequence set forth in SEQ ID NO: 3.
2. A method for expressing a nucleotide sequence in a plant, said method comprising introducing into a plant a DNA construct, said DNA construct comprising a promoter, and operably linked to said promoter a heterologous nucleotide sequence of interest, wherein said promoter comprises the nucleotide sequence set forth in SEQ ID NO: 3.
3. A method for expressing a nucleotide sequence in a plant cell, said method comprising introducing into a plant cell a DNA construct comprising a promoter operably linked to a heterologous nucleotide sequence of interest, wherein said promoter comprises the nucleotide sequence set forth in SEQ ID NO: 3.
4. A method for selectively expressing a nucleotide sequence in maize leaf, maize root, maize stalk, and maize tassel tissues, said method comprising introducing into a maize plant cell a DNA construct, and regenerating a transformed maize plant from said maize plant cell, said DNA construct comprising a promoter and a heterologous nucleotide sequence operably linked to said promoter, wherein said promoter comprises the nucleotide sequence set forth in SEQ ID NO: 3.
