The present invention relates to a process for increasing the phosphate content of starches of genetically modified plant cells in comparison with starches from corresponding wild-type plant cells by introducing a foreign nucleic acid molecule which codes for a soluble starch synthase II. The present invention furthermore relates to the overexpression of this soluble starch synthase II in the genetically modified plant cells. Furthermore, the present invention relates to rice starch and rice flour with improved quality characteristics, to rice grains comprising this rice starch, and to rice plants on which these rice grains grow.

Transgenic potato plants with increased hyaluronan production

Methods and means are provided for the modification of the reactivity of plant cell walls, particularly as they can be found in natural fibers of fiber producing plants by inclusion of positively charged oligosaccharides or polysaccharides into the cell wall. This can be conveniently achieved by expressing a chimeric gene encoding an N-acetylglucosamine transferase, particularly an N-acetylglucosamine transferase, capable of being targeted to the membranes of the Golgi apparatus in cells of a plant.

Cotton fibers having positively charged oligosaccharides

The present invention relates to plant cells and plants which synthesize an increased amount of glucosaminoglycans, and to methods for preparing such plants, and also to methods for preparing glucosaminoglycans with the aid of these plant cells or plants. Here, plant cells or genetically modified plants according to the invention have glucosaminoglycan synthase activity and additionally an increased glucosamine 6-phosphate acetyltransferase activity and an increased UDP-N-acetyl-glucosamine pyrophosphorylase activity compared to wild-type plant cells or wild-type plants. The present invention furthermore relates to compositions comprising plant cells having an increased glucosaminoglycan synthesis.

Plants which synthesize increased amounts of glucosaminoglycans

Methods for altering the reactivity of plant cell walls

The present invention relates to plant cells and plants having an increased content of N-acetylated glucosamine derivatives. Furthermore, the present invention relates to plant cells and plants which synthesize glucosaminoglycans. The present invention also provides processes for producing said plants and compositions comprising said plant cells.

Plants having an increased content of amino sugars

The present invention relates to plant cells and plants which synthesize an increased amount of hyaluronan, and to methods for preparing such plants, and also to methods for preparing hyaluronan with the aid of these plant cells or plants. Here, plant cells or genetically modified plants according to the invention have hyaluronan synthase activity and additionally an increased glutamine:fructose 6-phosphate amidotransferase (GFAT) activity and an increased UDP glucose dehydrogenase (UDP-Glc-DH) activity, compared to wild-type plant cells or wild-type plants. The present invention furthermore relates to the use of plants having increased hyaluronan synthesis for preparing hyaluronan and food or feedstuff containing hyaluronan.
