The present invention relates to plant cells and plants, which are genetically modified, whereby the genetic modification leads to an increase in the activity of a starch-phosphorylating OK1 protein in comparison to the corresponding wild type plant cells or wild type plants that have not been genetically modified. In addition, the present invention concerns means and methods for the manufacture of such plant cells and plants. These types of plant cells and plants synthesize a modified starch. Therefore, the present invention also concerns the starches synthesized from the plant cells and plants according to the invention, methods for manufacturing these starches, and the manufacture of starch derivatives of these modified starches, as well as flours containing starches according to the invention. Furthermore, the present invention also relates to nucleic acids, coding starch-phosphorylating OK1 proteins, vectors, host cells, plant cells, and plants containing such nucleic acid molecules. In addition, the present invention relates to OK1 proteins that have starch-phosphorylating activity.

Plants with increased activity of a starch phosphorylating enzyme

The present invention relates to a method for identifying proteins involved in the phosphorylation of starch and nucleic acids which code for such proteins. The present invention further relates to plant cells and plants which exhibit an altered activity of a protein which can be identified using the method according to the invention. Plant cells and plants of this type synthesise a modified starch. The present invention therefore also relates to the starch synthesised by the plant cells and plants according to the invention as well as to methods for the manufacture of this starch and to the manufacture of starch derivatives of this modified starch.

Methods for identifying proteins with starch phosphorylating enzymatic activity

The present invention relates to plant cells and plants, which are genetically modified, wherein the genetic modification leads to the reduction of the activity of a starch phosphorylating OK1 protein in comparison with corresponding wild type plant cells or wild type plants that have not been genetically modified. Furthermore, the present invention relates to means and methods for the manufacture of such plant cells and plants. Plant cells and plants of this type synthesise a modified starch. The present invention therefore also relates to the starch synthesised by 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. Furthermore, the present invention relates to nucleic acid molecules, which are suitable for manufacturing plants according to the invention.

The present invention relates to plant cells and plants, which are genetically modified, wherein the genetic modification leads to the increase of the activity of a starch phosphorylating OK1 protein and a starch phosphorylating R1 protein in comparison with corresponding wild type plant cells or wild type plants that have not been genetically modified. Furthermore, the present invention relates to means and methods for the manufacture of such plant cells and plants. Plant cells and plants of this type synthesize a modified starch. The present invention therefore also relates to the starch synthesized by 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. Furthermore, the present invention relates to nucleic acid molecules and vectors containing sequences which code for an OK1 protein and an R1 protein, as well as host cells which contain these nucleic acid molecules.
