Patent ID: 7259296

Claim:
A method for stimulating root growth or for enhancing the formation of lateral or adventitious roots, said method comprising introducing into a plant a nucleic acid molecule encoding a plant cytokinin oxidase selected from the group consisting of: a an isolated nucleic acid molecule comprising the DNA sequence as set forth in SEQ ID NO:26, or the complement thereof, b an isolated nucleic acid molecule comprising the RNA sequence encoding the amino acid sequence of SEQ ID NO:4, or the complement thereof, c an isolated nucleic acid molecule encoding the protein comprising the amino acid sequence as set forth in SEQ ID NO:4, or the complement thereof, and d an isolated nucleic acid molecule as defined in any of(a) to (c) characterized in that said nucleic acid molecule is DNA, genomic DNA, cDNA, synthetic DNA or RNA wherein T is replaced by U, and wherein expression of said nucleic acid molecule stimulates root growth or enhances the formation of lateral or adventitious roots.
