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.
