Abstract: The present invention relates to methods of increasing the cold tolerance of a plant or part thereof and/or preventing or inhibiting bolting of a plant, comprising deregulating phloem flux and plants or parts thereof having deregulated phloem flux. The invention also extends to the use of genes for deregulating phloem flux in a plant or part thereof; and/or increasing cold tolerance of a plant or part thereof; and/or preventing or inhibiting bolting in a plant. The invention also provides methods of selecting and/or producing a plant with deregulated phloem flux and/or increased cold tolerance and/or delayed or inhibited bolting. The invention also extends to constructs, isolated polynucleotides and polypeptides which can be used to deregulate phloem flux, plant cells transformed with such constructs, and to plants or parts thereof having deregulated phloem flux.

Abstract: The invention relates to tonoplast proton/sugar antiporter proteins, more particularly tonoplast proton/saccharose antiporter proteins, the nucleotide sequences which encode them and uses thereof for producing transgenic plants with an increased saccharose concentration. The invention also includes methods for producing transgenic plants with an increased saccharose concentration, methods for increasing the saccharose concentration in plants, and for identifying plants which are suitable for creating a higher saccharose concentration.

Abstract: The invention relates to a method of enhancing the seed yield and promoting the growth of monocotyledonous or dicotyledonous plants by overexpression of TMT (tonoplast monosaccharide transporter) protein in osogenic or transgenic plant cells. The invention further concerns a transgenic plant having the property of an enhanced seed yield and increased growth as compared with the wild type, comprising a nucleotide sequence which codes for a TMT (tonoplast monosaccharide transporter) protein, as well as a regulatory nucleotide sequence, operably linked therewith, for the control of an increased gene expression of the TMT protein in the plant cells of the transgenic plant. It further relates to the use of the transgenic plant for the cultivation or production of cultivated plants or useful plants, or biomass, oils or proteins produced therefrom.

Abstract: Transgenic plant cells and plants are described which, compared to wildtype cells and plants, exhibit an increased yield, in particular, an increased oil and/or starch content and which preferably synthesize a modified starch. The described plants exhibit an increase or a decrease of the plastidial ADP/ATP translocator activity.

Abstract: The invention relates to a method of generating or increasing a resistance in organisms, in particular plants, to biotic and abiotic stress. The method is based on a change adapted to be carried out by various methods in the distribution of ATP and/or ADP in cells of the organism.
