Patent ID: 8138389

Claim:
A method for increasing seed size or weight 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:11 or 30, or the complement thereof, (b) an isolated nucleic acid molecule comprising the RNA sequence encoding the amino acid sequence of SEQ ID NO:12, 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: 12, 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, wherein the isolated nucleic acid molecule is preferentially expressed in the seed of the plant and wherein said expression increases seed size or weight.
