    • 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 altering the metabolism of or causing death of the specific cells and/or nearby cells. In particular, the promoter sequence is operable to direct expression in lateral bud or lateral shoot and the nucleic acid encoding at least one gene product capable of disrupting the metabolism of or causing the death of the lateral bud or lateral shoot or nearby cells. Preferably the promoter sequence comprises the sequence shown as SEQ ID No. 1 or SEQ ID No. 7 or SEQ ID No. 4, or a part thereof capable of regulating expression of a gene, or a sequence having at least 60%, preferably at least 75%, homology to SEQ ID No. 1 or SEQ ID No. 7 and being capable of regulating expression of a gene.
    • 一种在植物中修饰形态的方法,包括向植物中引入至少一个嵌合基因,其包含可操作地与核酸序列相关的启动子序列,所述启动子序列可操作以指导在植物的特定细胞中的表达和编码的核酸序列 至少一种能够改变特定细胞和/或附近细胞的代谢或引起死亡的基因产物。 特别地,启动子序列可操作以指导侧芽或侧枝中的表达,以及编码能够破坏侧芽或侧芽或附近细胞的代谢或引起侧芽或侧枝或附近细胞死亡的至少一种基因产物的核酸。 优选地,启动子序列包含SEQ ID No.1或SEQ ID No.7或SEQ ID No.4所示的序列,或其能调节基因表达的部分或具有至少60%的序列,优选在 至少75%与SEQ ID No.1或SEQ ID No.7具有同源性,并且能够调节基因的表达。
