Abstract

The present invention relates to genetically modified monocotyledonous plant cells and plants whose starch has an apparent amylose content of less than 5% by weight and an increased activity of a protein with the activity of a starch synthase II and an increased activity of a protein with the activity of a glucan, water dikinase. Such plants synthesize starch with an increased hot-water swelling power. Methods and processes for the generation/preparation of these plant cells, plants, starches and flours are likewise subject matter of the present invention.
