Abstract: Nucleic acid molecules are described encoding a starch granule-bound protein from maize as well as methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch. Moreover, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.

Abstract: Nucleic acid molecules are described encoding a starch granule-bound protein as well as methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch with modified viscosity properties and a modified phosphate content. Moreover, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.

Abstract: The present invention relates to plant cells and plants which synthesize hyaluronan and to methods for preparing such plants, and also to methods for preparing hyaluronan with the aid of these plant cells or plants. Furthermore, the present invention relates to the use of plants for preparing hyaluronan and to food or feed which comprises hyaluronan.

Abstract: Transgenic plant cells and plants are described which, compared to wildtype cells and plants, exhibit an increased yield, in particular, an increased oil and/or starch content and which preferably synthesize a modified starch. The described plants exhibit an increase or a decrease of the plastidial ADP/ATP translocator activity.

Abstract: The invention relates to DNA sequences coding for proteins having the enzymatic activity of an amylosucrase which allows the synthesis of linear &agr;-1,4 glucans from the substrate sucrose by bacteria, fungi and plants or in cell-free systems. The invention furthermore describes plasmids and bacteria containing these DNA sequences as well as processes for the production of plants and microorganisms capable of intracellularly or extracellularly expressing a polypeptide having amylosucrase activity. The invention furthermore relates to the production of pure fructose using proteins exhibiting the enzymatic activity of amylosucrase.
