Genetically modified plants synthesizing starch with increased swelling power

摘要

Genetically modified plant cells with increased starch synthase II activity and increased glucan-water dikinase activity are new. Independent claims are also included for: (1) plants comprising the cells; (2) propagules of the plants; (3) producing genetically modified plants by genetically modifying a plant cells to increase starch synthase II activity and glucan-water dikinase activity, regenerating a plant from the cell and optionally using the plant to generate other plants; (4) producing modified starch by extracting starch from a cell, plant or propagule as above; (5) modified starch produced as above; (6) producing derivatized starch by derivatizing the modified starch; (7) derivatized starch produced as above; (8) flour comprising the modified starch; (9) producing flour by milling plants or propagules as above.
