| 摘要 |
<p>The present invention relates to recombinant nucleic acid molecules which contain a DNA sequence that codes for a protein having the enzymatic activity of a sucrose isomerase. Said DNA sequence is controlled by regulatory sequences of a promoter that is active in plants. The invention also relates to vectors and host cells which contain the inventive recombinant nucleic acid molecules. The invention further relates to methods for producing transformed plant cells and plants using the recombinant nucleic acid molecules and vectors. The invention further relates to transgenic plants, the crop products and reproducing material thereof as well as transgenic plant cells that contain the inventive nucleic acid molecules or vectors or are produced by the inventive method. The invention particularly relates to a method for producing non-cariogenic sugars in plant cells and plants. According to said method, an inventive nucleic acid molecule or vector is transmitted to plant cells. The invention also relates to the use of DNA sequences which code for a protein having the enzymatic activity of a sucrose isomerase for producing non-cariogenic sugars in plant cells and plants.</p> |
