Abstract
This invention relates to an isolated nucleic acid fragment encoding a sorbitol biosynthetic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the sorbitol biosynthetic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the sorbitol biosynthetic enzyme in a transformed host cell.
Claims8
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having sorbitol dehydrogenase activity, wherein the polypeptide has an amino acid sequence of at least 90% sequence identity, based on the Clustal method of alignment, when compared to SEQ ID NO:20, or
- (b) a full-length complement of the nucleotide sequence of (a).
Dependencies are inferred from the claim text.
