Abstract:
1. A modified starch obtainable from a transgenic plant cell, or from a plant comprising said plant cell, said plant cell exhibiting a reduction in the amount of a protein that is present in the plant cell in starch granule-bound form as well as in soluble form and that is involved in the phosphorylation of starch when expressed in plants and/or that increases the phosphorylation of glycogen when expressed in E. coli , said protein encoded by a nucleic acid molecule selected from the group consisting of: (a) a nucleic acid molecule encoding a protein with the amino acid sequence indicated in SEQ ID NO: 2; (b) a nucleic acid molecule comprising the coding region of the nucleotide sequence indicated in SEQ ID NO: 1; (c) a nucleic acid molecule hybridizing to the nucleic acid molecule of (a) or (b) under stringent conditions; (d) a nucleic acid molecule that has more than 80% sequence identity to the nucleic acid molecule of (a) or (b); and (e) a nucleic acid molecule the sequence of which is degenerate as a result of the genetic code to the nucleic acid molecule of (a) or (b) or (c) or (d); wherein said modified starch has a phosphate content reduced by at least 50% compared to starch from a non-transgenic plant cell.
