Abstract
This invention relates to isolated nucleic acid fragments encoding fructosyltransferases. More specifically, this invention relates to polynucleotides encoding 1-FFTs, 6-SFTs, or 1-SSTs. The invention also relates to the construction of a recombinant DNA constructs encoding all or a portion of the fructosyltransferases, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the fructosyltransferases in a transformed host cell.
Claims10
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having fructan:fructan fructosyltransferase activity, wherein the polypeptide has an amino acid sequence of at least 95% sequence identity, based on the Clustal V method of alignment, when compared to SEQ ID NO:
- 4, or
- (b) a complement of the nucleotide sequence, wherein the complement and the nucleotide sequence consist of the same number of nucleotides and are 100% complementary.
