Abstract: A combination of DNA sequences is described which, in transgenic plant cells and plants, results in the formation of a modified starch which differs from starch synthesized naturally in the cells, especially in respect of its degree of branching and its phosphate content. A process for the production of genetically modified plants which are modified in respect of the physical and chemical properties of the synthesized starch due to the expression of artificially introduced DNA sequences, the plants obtainable by this process, and the modified starch obtainable from these plants, are also described.

Abstract: Plasmids containing DNA sequences which when inserted into the genome of a plant modify the carbohydrate or protein concentration and the carbohydrate or protein composition, and plant cells and plants that contain these plasmids.DNA sequences located in plasmids reduce ADP-glucose-pyrophosphorylase activity in the plant and thereby the starch concentration, while at the same time increase the mono- and oligosaccharide concentration. Other DNA sequences in plasmids reduce or increase the protein concentration. Plants that contain these plasmids are suitable inter alia for the extraction of sugar or as protein-enriched food or fodder.
