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.
