Abstract
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.
Claims2
A construct comprising a first nucleotide sequence which shares sufficient sequence identity with SEQ ID NO:
- 4 the ckx1-2 promoter of that, when expressed, a hairpin RNA molecule is formed which suppresses expression of a second nucleotide sequence operably linked to the ckx1-2 promoter.
