Plasmids containing DNA sequences which provide changes in carbohydrate and protein concentration and carbohydrate and protein compositions in plants, and plant cells and plants containing these plasmids

摘要

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