Abstract
Nucleic acid molecules are described encoding enzymes involved in the starch synthesis in plants. These enzymes are a novel isotype of soluble starch synthesis from maize. Furthermore, the invention relates to vectors containing such nucleic acid molecules and to host cells, which have been transformed with the nucleic acid molecules, in particular to transformed plant cells or plants regenerable therefrom, which exhibit an increased or reduced activity of the described proteins.
Claims27
An isolated nucleic acid molecule comprising a nucleic acid sequence encoding a protein with the biological activity of a type I soluble starch synthase or comprising the complementary strand of said nucleic acid sequence, 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) a nucleic acid sequence that is the coding region of SEQ ID NO:
- 1;
- (c) a nucleic acid sequence that has more than 90% sequence identity to the entire coding region of SEQ ID NO:
- 1;
- (d) a fragment of the nucleic acid sequence of (a), (b) or (c), wherein the fragment encodes a protein which has the biological activity of a type I soluble starch synthase;
- and
- (e) a nucleic acid sequence that deviates from the sequence of any one of the nucleic acid sequences of (a), (b), (c) or (d) due to the degeneracy of the genetic code.
An isolated nucleic acid molecule comprising a nucleic acid sequence encoding a protein with the biological activity of a type I soluble starch synthase, wherein the nucleic acid sequence is between 95% and 100% identical to the entire coding region of SEQ ID NO:
- 1.
An isolated nucleic acid molecule comprising the nucleic acid sequence of SEQ ID NO:
- 1.
