| 摘要 |
The present invention relates to plant cells and plants that are genetically modified, whereby the genetic modification leads to a decrease in the activity of a starch dephosphorylating LSF-2 protein and a starch dephosphorylating SEX4 protein in comparison to corresponding wild type plant cells or wild type plants that have not been genetically modified. The present invention also relates to means and methods for the manufacture of such plant cells and plants. These types of plant cells and plants synthesise a modified starch. Therefore, the present invention also concerns the starch synthesised from the plant cells and plants according to the invention, methods for the manufacture of this starch, and the manufacture of starch derivatives of this modified starch, as well as flours containing starches according to the invention. In addition, the present invention relates to vectors comprising nucleic acids encoding a starch dephosphorylating LSF-2 protein starch dephosphorylating SEX4 protein, host cells such as plant cells, and plants containing such chimeric genes. |
