Patent number: 10428341Abstract: 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.Type: GrantFiled: October 5, 2006Date of Patent: October 1, 2019Assignee: BASF SEInventors: Claus Frohberg, Bernd Essigmann

Patent number: 9404119Abstract: 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.Type: GrantFiled: July 15, 2013Date of Patent: August 2, 2016Assignee: Bayer CropScience N.V.Inventors: Marc De Block, Frank Meulewaeter, Rainhard Koch, Bernd Essigmann
