Abstract
An isolated nucleic acid fragment encoding a chalcone isomerase is disclosed. Also of concern is the synthesis of a recombinant DNA construct encoding all or a portion of the chalcone isomerase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the chalcone isomerase in a transformed host cell.

An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having chalcone isomerase activity, wherein the amino acid sequence of the polypeptide and the amino acid sequence of SEQ ID NO:2, 4 or 6 have at least 80% sequence identity, or
- (b) the full-length complement of the nucleotide sequence of (a).
An isolated polynucleotide comprising a first nucleotide sequence, wherein the first nucleotide sequence contains at least 30 nucleotides, and wherein the first nucleotide sequence is comprised by another polynucleotide, wherein the other polynucleotide includes:
- (a) a second nucleotide sequence, wherein the second nucleotide sequence encodes a polypeptide having chalcone isomerase activity, wherein the amino acid sequence of the polypeptide and the amino acid sequence of SEQ ID NO:2, 4 or 6 having at least 80% sequence identity, or
- (b) the complement of the second nucleotide sequence of (a).
An isolated polypeptide having chalcone isomerase activity, wherein the amino acid sequence of the polypeptide and the amino acid sequence of SEQ ID NO:2, 4 or 6 have at least 80% identity.
