Abstract
Nucleic acid molecules are described encoding a starch granule-bound protein as well as methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch with modified viscosity properties and a modified phosphate content. Moreover, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.
Claims18
A method for reducing undesirable products of Maillard reactions comprising
- producing french fries or crisps from a tuber comprising genetically modified potato plant cells having a reduced expression of a nucleic acid molecule, wherein said nucleic acid molecule comprises
- (a) a nucleic acid molecule encoding a protein with the amino acid sequence of SEQ ID NO:
- 2;
- (b) a nucleic acid molecule comprising the coding region of the nucleotide sequence of 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 greater than 90% 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);
- and wherein undesirable able products of Maillard reactions are reduced in said french fries or crisps as compared to french fries or crisps produced from a wild-type tuber.

A method for decreasing the amount of a reducing sugar in a tuber comprising
- storing at low temperatures a tuber comprising genetically modified potato plant cells having a reduced expression of a nucleic acid molecule, wherein said nucleic acid molecule comprises
- (a) a nucleic acid molecule encoding a protein with the amino acid sequence of SEQ ID NO:
- 2;
- (b) a nucleic acid molecule comprising the coding region of the nucleotide sequence of SEQ ID NO:
- 1;
- (c) a nucleic acid molecule hybridizing to the nucleic acid molecule of (i) or (ii) under stringent conditions;
- (d) a nucleic acid molecule that has greater than 95% 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 (i) or (ii) or (iii) or (iv);
- and wherein said tuber has a decreased amount of a reducing sugar as compared to the amount of the same reducing sugar in a wild-type tuber.
