The invention concerns means and methods enabling the provision of plants showing an altered flowering behaviour, and, particularly, genetically modified plants showing an early or delayed flower formation when compared to not correspondingly modified but otherwise similar wild-type plants, as well as a tissue-specific promoter which may be utilized in a method for producing these genetically modified plants. The invention is based on the finding that the flowering behaviour of plants may be influenced by enhancing the saccharose-cleaving activity specifically in the apical meristem of the plants. In this context, an enhancement of the saccharose-cleaving activity specifically in the apoplast of the apical meristem of plants results in an early flower formation whereas an enhancement of the saccharose-cleaving activity specifically in the cytoplasm of cells of the apical meristem leads to a delayed flower formation compared with corresponding not modified wild- type plants.

L'invention concerne des systèmes et des procédés permettant d'obtenir des plantes à floraison modifiée, et en particulier des plantes génétiquement modifiées à floraison anticipée ou retardée par rapport aux plantes sauvages qui n'ont pas subi les modifications correspondantes mais qui sont par ailleurs identiques. L'invention concerne en outre un promoteur spécifique aux tissus, susceptible d'être utilisé dans un procédé relatif à la production desdites plantes génétiquement modifiées. On a constaté que la floraison des plantes pouvait être modifiée par augmentation de l'activité de clivage du saccharose, spécifiquement dans le méristème apical des plantes. En conséquence, toute augmentation de cette activité spécifiquement dans l'apoplaste du méristème apical des plantes entraîne une floraison anticipée, mais toute augmentation de ladite activité spécifiquement dans le cytoplasme des cellules du méristème apical retarde la floraison par rapport aux plantes sauvages qui n'ont pas subi les modifications correspondantes.
