Abstract: The present invention relates to promoters which cause, in plants, permanent leaf-specific expression of an encoding nucleotide sequence under the control of said promoters, for example a sequence which imparts resistance or an increase in the photosynthetic performance.

Abstract: Plasmids are described having DNA sequences that after insertion into the genome of the plants cause changes in the carbohydrate concentration and the carbohydrate composition in regenerated plants. These changes can be obtained from a sequence of a branching enzyme that is located on these plasmids. This branching enzyme alters the amylose/amylopectin ratio in starch of the plants, especially in commercially used plants.

Abstract: There are described ferredoxin:NADP reductase inhibitors, an assay system for the search for such inhibitors, and their use as herbicides.

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.

Abstract: This invention relates to DNA sequences and plasmids containing these sequences which can be integrated into a plant genome and which modify the activity of the sucrose-phosphate-synthase (sps) of the plant. The invention relates further to derivatives of the DNA sequences of the invention that are obtained by exchange of single bases or by deletion or insertion of base sequences and which code for proteins with comparable activity to sucrose-phosphate-synthase. Methods for transforming plant cells and regenerating plants from the cells which exhibit modified sucrose-phosphate-synthase activity are also described.

Abstract: A protein having transketolase activity, containing an amino acid sequence which is a part sequence of at least 100 amino acids from SEQ ID NO 2, and nucleic acids coding for this protein and its use are described.

Abstract: There is disclosed plasmids for the preparation of transgenic plants which are modified through the transfer and the expression of genes localized on the plasmids, that influence the sugar metabolism or the sugar partitioning within a plant. In addition, transgenic plants with modified sugar metabolism or sugar partitioning are described. The genes cause a modified distribution of assimilates in the transgenic plant which result in significant changes in plant habit, such as size, leaf shape, internode separation and root formation, as well as improvements in plant yield. Plasmids and methods are also described which enable foreign proteins to be directed into specific tissues or portions of transgenic plants, including vacuoles, leaves and sink organs.

Abstract: DNA sequences are described, that by integration in a plant genome cause the activity of the sucrose-phosphate-synthase (SPS) of the plant to be changed, plasmids, containing these DNA sequences as well as transgenic plants that by introduction of the DNA sequences causes changes in the activity of sucrose-phosphate-synthase.

Abstract: There are described 5' transcriptional regulatory regions of plant genes which ensure sink organ specific expression of cis-linked DNA sequences as well as recombinant double stranded DNA molecules comprising these 5' regulatory regions. Furthermore the present invention relates to a method for producing transgenic plants which show a sink tissue specific expression of a desired DNA sequence.

Abstract: A method of and plasmids for producing specific gene expression in the guard cells of plants. In particular, 5' transcriptional regulatory promoter regions are provided for guard cell specific expression. In addition, methods for preparing an expression cassette, plasmids, and the use of the cassettes and plasmids to produce transgenic plant cells and plants are described.

Abstract: Plasmids that comprise a DNA sequence coding for a protein that modifies the metabolism of soluble sugars, for example, an inorganic pyrophosphatase agent and plant cells comprising those plasmids, for the production of transgenic plants that are modified in habit and yield arc described, the plants being modified in habit by the transfer and the expression of genes that intervene in sugar metabolism or sugar distribution inside a plant.

Abstract: There is disclosed plasmids for the preparation of transgenic plants, as well as the plants, that are modified through the transfer and the expression of genes influencing the sugar metabolism or the sugar partitioning within a plant, which are localised on these plasmids.The transferred genes cause a modified distribution of assimilates in the transgenic plant which result in significant changes in habit, such as size, leaf shape, internode separation and root formation, as well as improvements in yield.Plasmids are also described which enable foreign proteins to be directed into the vacuoles of transgenic plants.

Abstract: There is described a new DNA sequence of an expression cassette on which the potato tuber specific regulatory regions are localised as well as the transfer of this DNA sequence into the plant genome using agrobacteria as transfer micro-organisms. The DNA sequence contains a patatin gene with a patatin gene promoter. The transfer DNA sequence acts both for regulating endogenous as well as for preparation of heterologous products in crops.
