A plant cell (A) modified so that it has, relative to the wild type, reduced activities of at least one each of endogenous starch synthase III (SSIII) and branching enzymes (BE) I and II proteins, is new. Independent claims are also included for: (1) plants containing cells (A); (2) preparing (A) having modified starch synthesis; (3) preparing genetically modified plants by regeneration of (A); (4) replicative material from the plants of (3); (5) composition containing at least one nucleic acid (NA) able to reduce synthesis of at least one of SSIII or BEI/II when introduced into a plant cell; (6) plant cell transformation system comprising at least one NA and a plant cell; (7) host cell containing the composition of (5); (8) starch (St) produced by the new cells, plants or replicative material; (9) preparing St by extraction from the new cells, plants or replicative material; (10) processed products (especially food, animal feeds, dyes, adhesives, building material and sound proofing) that contain St; and (11) starch-containing parts of the new plants. |
