There are described plasmids for the production of transgenic plants, and these plants which are altered by the transfer and the expression of genes which are located on these plasmids and which engage in the sugar metabolism or sugar partitioning within a plant. The transferred genes cause an altered distribution of photoassimilates in the transgenic plants, which results in substantial modifications in the appearance such as size, leaf shape, distance between the internodes and root production, and in modifications of the yield. There are furthermore described plasmids which allow foreign proteins to be directed in the vacuoles of transgenic plants. |
