A method of modifying at least one carbohydrate in a tissue of a plant is described. The method is typically applied to a sugarcane plant of the genusmethod and includes the steps of inserting into a plant cell a gene silencing cassette which includes nucleic acid operably linked to transcription elements such as a monocotyledonous promoter for transcribing the nucleic acid in a plant cell, wherein transcription of the nucleic acid decreases activity of UMP synthase. The method further includes the steps of regenerating a transgenic plant from the plant cell and producing the tissue with increased carbohydrate content. Vectors for use therefor, as well as a transformed plant cell and a transgenic plant or plant part containing or derived from a transformed plant cell are also described.

Method of modifying the carbohydrate content of a plant

Nucleic acid molecules are described encoding a starch granule-bound protein as well as methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch with modified viscosity properties and a modified phosphate content. Moreover, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.

Plants which synthesize a modified starch, process for the production thereof and modified starch

The present invention relates to nucleic acid molecules encoding enzymes which are involved in the starch synthesis in plants. These enzymes are starch synthases from wheat. The invention further relates to vectors and host cells containing said nucleic acid molecules, in particular transformed plant cells and plants regenerated from these cells, which exhibit an increased or a reduced activity of the described starch synthases.

Nucleic acid molecules encoding enzymes from wheat which are involved in starch synthesis

Nucleic acid molecules encoding an alternansucrase are provided. Moreover, vectors, host cells and plant cells transformed by the herein-described nucleic acid molecules and plants containing them are provided. Furthermore, methods are described for preparing transgenic plants which synthesize the carbohydrate alternan, because of the insertion of nucleic acid molecules encoding an alternansucrase. Moreover, methods for preparing alternan and products resulting from them are provided.

DNA sequences coding for enzymes capable of facilitating the synthesis of linear &#x25a1;-1,4 glucans in plants, fungi and microorganisms. The invention relates to DNA sequences Coding for proteins having the enzymatic activity of an amylosucrase which allows the synthesis of linear &#x25a1;1,4 glucans from the substrate sucrose by bacteria, fungi and plants or in cell-free systems. The invention furthermore describes plasmids and bacteria containing these DNA sequences as well as processes for the production of plants and microorganisms capable of intracellularly or extracellularly expressing a polypeptide having amylosucrase activity. The invention furthermore relates to the production of pure fructose using proteins exhibiting the enzymatic activity of amylosucrase.
