The invention relates to recombinant nucleic acid molecules containing two or more nucleotide sequences which code enzymes involved in the metabolism of starch. The invention also relates to methods for producing transgenic plant cells and plants which synthesize a starch that is modified with regard to the phosphate content and side-chain structure thereof. In addition, the invention relates to vectors and host cells which contain the inventive nucleic acid molecules, to the plant cells and plants produced using the inventive methods, to the starch which is synthesized by the inventive plant cells and plants, and to methods for producing this starch.
