Abstract
The present invention relates to recombinant nucleic acid molecules which contain two or more nucleotide sequences which encode enzymes which participate in the starch metabolism, methods for generating transgenic plant cells and plants which synthesize starch which is modified with regard to its phosphate content and its side-chain structure. The present invention furthermore relates to vectors and host cells which contain the nucleic acid molecules according to the invention, the plant cells and plants which originate from the methods according to the invention, to the starch synthesized by the plant cells and plants according to the invention, and to processes for the preparation of this starch.
Claims20
An isolated recombinant nucleic acid molecule comprising
- a) at least one nucleotide sequence encoding a potato soluble starch synthase III;
- and
- b) one or more nucleotide sequences which encode a branching enzyme,
- wherein said isolated recombinant nucleic acid molecule inhibits the synthesis of endogenous soluble starch synthase III and endogenous branching enzyme when introduced into plants.
A transgenic plant cell, comprising
- a) at least one nucleotide sequence encoding a potato soluble starch synthase III;
- and
- b) one or more nucleotide sequences encoding a branching enzyme,
- wherein said nucleotide sequences inhibit the synthesis of endogenous soluble starch synthase III and endogenous branching enzyme.
A method of generating a transgenic plant cell, wherein
- a) at least one nucleotide sequence encoding a potato soluble starch synthase III;
- and
- b) one or more nucleotide sequences encoding a branching enzyme are simultaneously or subsequently integrated into the genome of the transgenic plant cell, thereby inhibiting the synthesis of endogenous soluble starch synthase III and endogenous branching enzyme.
