Compositions and methods for regulating expression of heterologous
polynucleotide sequences in a plant are provided. Compositions are novel
nucleotide sequences comprising an isolated stress-induced promoter
natively linked to the maize CBF1 or CBF2 coding region. A method for
expressing a heterologous polynucleotide sequence in a plant using the
regulatory sequences disclosed herein is provided. The method comprises
transforming a plant cell to comprise a heterologous polynucleotide
sequence operably linked to one or more of the regulatory sequences of
the present invention and regenerating a stably transformed plant from
the transformed plant cell.
