Patent ID: 8575423

Claim:
A method of modifying morphology in a plant comprising: introducing into a plant at least one chimaeric gene comprising a promoter sequence operably associated with a nucleic acid sequence, the promoter sequence being operable to direct expression in specific cells of the plant and the nucleic acid sequence encoding at least one gene product capable of at least one of altering the metabolism of and causing death of at least one of the specific cells and nearby cells, wherein the promoter sequence is operable to direct expression in at least one of a lateral bud and a lateral shoot, and wherein the promoter sequence comprises at least one of the sequences selected from the group consisting of SEQ ID No. 1, SEQ ID No. 7, a sequence having at least 99% homology to SEQ ID NO. 1 or SEQ ID NO. 7, and a sequence capable of hybridizing to SEQ ID No. 1 or SEQ ID No. 7 under stringent hybridization conditions, said stringent hybridization conditions comprising washing for 2×15 minutes with a 0.1×SSC, 0.5% SDS buffer at a temperature of 65° C.
