Root-preferred promoter and methods of use

摘要

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 TIP2-3. 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.

主权项

1. An expression cassette comprising a polynucleotide comprising the nucleotide sequence of SEQ ID NO: 1 operably linked to a heterologous nucleotide sequence of interest, wherein the polynucleotide initiates transcription in a plant in a root-preferred manner.
