Abstract: Nucleic acid molecules are described which encode polypeptides having the enzymatic activity of a fructosyltransferase. Also, vectors, host cells and transgenic plants are described which contain such nucleic acid molecules. Furthermore, processes for producing polyfructose, particularly that of the inulin type, using the hosts described and/or the fructosyltransferase produced by them are described.

Abstract: Described are nucleic acid molecules encoding enzymes having fructosyl polymerase activity. These enzymes are sucrose dependent sucrose fructosyltransferases (SST) enzymes. Furthermore, vectors and host cells are described containing the nucleic acid molecules, in particular transformed plant cells and plants that can be regenerated from them and that express the described SSTs. Furthermore, methods for the production of short-chain fructosyl polymers using the described hosts and/or the SSTs produced by them are described.

Abstract: Nucleic acid molecules are described encoding proteins with the enzymatic activity of a fructosyl transferase. These enzymes are fructosyl transferases (FFT). Moreover, vectors and host cells are described containing the nucleic acid molecules of the invention, in particular transformed plant cells, plant tissue and plants regenerable therefrom, which express the described FFT. Furthermore, methods for the production of long-chain inulin by using the described proteins, hosts, in particular the plant cells and/or FFT produced by them, are described.

Abstract: The invention provides compositions and methods enabling the provision of plants showing an altered flowering behavior, 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 behavior 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.
