Abstract
The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a promoter for the gene encoding Sorghum bicolor pLTP. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequences disclosed herein is provided. The method comprises transforming a plant or plant cell with a nucleotide sequence operably linked to one of the promoters of the present invention.
Claims19
An expression cassette comprising a nucleotide sequence comprising 600 contiguous nucleotides of the sequence set forth in SEQ ID NO:
- 1 operably linked to a heterologous nucleotide sequence of interest, wherein said nucleotide sequence initiates transcription in a plant cell.
A method for expressing a nucleotide sequence in a plant or a plant cell, said method comprising introducing into the plant or the plant cell an expression cassette comprising a promoter operably linked to a heterologous nucleotide sequence of interest, wherein said promoter comprises a nucleotide sequence comprising at least 600 contiguous nucleotides of the sequence set forth in SEQ ID NO:
- 1, wherein said nucleotide sequence initiates transcription in said plant.
A method for expressing a nucleotide sequence in a root-preferred manner in a plant, said method comprising introducing into a plant cell an expression cassette, and regenerating a plant from said plant cell, said plant having stably incorporated into its genome the expression cassette, said expression cassette comprising a promoter operably linked to a heterologous nucleotide sequence of interest, wherein said promoter comprises a nucleotide sequence comprising at least 600 contiguous nucleotides of the sequence set forth in SEQ ID NO:
- 1, wherein said sequence initiates transcription in a plant root cell.
