Abstract
Nucleic acid molecules encoding enzymes which participate in the starch synthesis in plants are described. These enzymes are a novel isotype of starch synthase. Furthermore, the invention relates to vectors and hose cells which were transformed with the described nucleic acid molecules, in particular to transformed plant cells and to plants which may be regenerated therefrom and which exhibit an increased or reduced activity of the described proteins.
Claims14
An isolated nucleic acid molecule comprising a regulatory element operably linked to a part of a nucleic acid sequence in antisense orientation thereto, wherein the nucleic acid sequence is selected from the group consisting of:
- (a) a nucleic acid sequence encoding a protein comprising the amino acid sequence of SEQ ID NO:
- 2;
- (b) the nucleic acid sequence of SEQ ID NO:
- 1;
- and
- (c) a nucleic acid sequence that has more than 90% sequence identity to the nucleic acid sequence of (a) or (b);
- wherein the part is sufficient to reduce the expression of a soluble starch synthase gene in a plant cell when introduced in antisense orientation with respect to the regulatory element.
