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.

Method for increasing cold or frost tolerance in a plant

A nucleic acid suitable for reducing the enzymatic activity of an invertase for configuring a sucrose storage organ of a plant, wherein the sucrose concentration is increased relative to the sucrose concentration of an unchanged control sucrose storage organ of the same genotype at a comparable stage of development. The increase in sucrose concentration by X percentage points can thereby lead to a changed or unchanged sucrose storage organ yield, wherein, in the case of a reduction in the sucrose storage organ yield, the reduction is a maximum of 5X percent. The invention further relates to a method for increasing the sucrose yield in agricultural production of sugar beet or sugar cane plants, wherein sugar beet or sugar cane plants are used, the genetic makeup thereof being set up for reducing the enzymatic activity of an invertase.

Method for increasing sucrose yield in agricultural production of sugar beet and sugar cane

The invention relates to the biotechnological production of isomaltulose and isomaltulose-containing compositions and improved means, therefore particularly microbial cells.

Microorganisms having enhanced sucrose mutase activity

For the biotechnological production of isomaltulose and compositions containing isomaltulose from saccharose the invention provides improved means, particularly a sucrose mutase with improved product specificity as well as microbial cells containing the improved sucrose mutase.

Sucrose mutase with improved product specificity

The invention relates to a method and means for the bioengineered fermentative production of solvents, in particular of butanol, acetone and ethanol, and of short-chained carboxylic acids such as acetic acid and butyric acid, in particular in host cells of the species. The invention provides new methods and means for regulating the expression of the enzyme activities involved in acid production and or solvent production of the host cell.

Production of acid and solvent in microorganisms

The present invention relates to a nucleic acid molecule encoding a vacuolar invertase and its use for modifying the plant saccharose metabolism, in particular in the vacuole of the cell of a plant storage organ. The present invention also relates to a fragment of the nucleic acid molecule, a vector containing the nucleic acid molecule or a fragment thereof, as well as a host cell, in particular a plant cell that contains the nucleic acid molecule or a fragment thereof. The present invention also comprises a transgenic plant, methods for producing a transgenic plant, as well as methods for modifying the saccharose metabolism of a plant, in particular of a plant part.

Nucleic acids coding for vacuolar invertases, vegetal cells and plants containing said nucleic acids and the use thereof
