The present invention provides compositions and methods for regulating
expression of nucleotide sequences in a plant. Compositions may comprise
a novel nucleic acid sequence for a promoter with tissue specificity
and/or cytokinin inducibility. A method for expressing a heterologous
nucleotide sequence in a plant using the promoter sequence is also
provided. The method comprises transforming a plant cell to contain a
heterologous nucleotide sequence operably linked to the promoter of the
present invention and regenerating a stably transformed plant from the
transformed plant cell. Other methods provide for downregulation of
cytokinin oxidase in a plant.
