Nucleic acid molecules are described which encode enzymes involved in starch synthasis in plants. These enzymes are wheat isoamylases. The invention furthermore relates to vectors and host cells which contain the above-described nucleic acid molecules, in particular to transformed plant cells and plants which can be regenerated from these and which have an increased or reduced activity of the isoamylases according to the invention.

Nucleic acid molecules which code for enzymes derived from wheat and which are involved in the synthesis of starch

The present invention relates to promoters which permit a caryopsis-specific expression or suppression of genes in genetically modified plants, to methods for the tissue-specific gene expression or gene suppression in plants, expression cassettes, recombinant vectors and host cells containing such promoters, to transgenic plant cells and plants transformed with said promoters, and to methods for generating such plant cells and plants.

Promoters for gene expression in caryopses of plants

The invention relates to nucleic acid molecules which code for enzymes and which are involved in the synthesis of starch in plants. These enzymes concern isoamylases derived from wheat. The invention also relates to vectors and host cells which contain the described nucleic acid molecules, especially transformed plant cells and plants which can be regenerated therefrom, which exhibit an increased or reduced activity of the inventive isoamylases.

Nucleic acid molecules encoding wheat enzymes involved in starch synthesis

Nucleic acid molecules are described which encode wheat enzymes involved in starch synthesis in plants. These enzymes are soluble wheat starch synthases. The invention furthermore relates to vectors and host cells which contain the above-described nucleic acid molecules. In particular to transformed plant cells and plants which can be regenerated from these and which have an increased or reduced activity of the soluble starch synthases according to the invention.

The present invention provides promoters which bring about a caryopsis-specific expression of coding nucleotide sequences controlled by them, and to expression cassettes, recombinant vectors and host cells containing such promoters. Transformed transgenic plant cells and plants and methods for generating them, are also described.
