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 root-preferred promoter for the
gene encoding CRWAQ81. A method for expressing a heterologous nucleotide
sequence in a plant using the promoter sequences disclosed herein is
provided. The method comprises stably incorporating into the genome of a
plant cell a nucleotide sequence operably linked to the root-preferred
promoter of the present invention and regenerating a stably transformed
plant that expresses the nucleotide sequence.
