Patent ID: 7968766

Claim:
A method of selecting an isolated polynucleotide that reduces the level of expression of a UDP-galactose 4-epimerase polypeptide in a plant cell, the method comprising the steps of: (a) constructing a recombinant DNA construct comprising a promoter operably linked to an isolated polynucleotide comprising a nucleotide sequence of at least 60 contiguous nucleotides of SEQ ID NO:13; (b) introducing the recombinant DNA construct into a plant cell; (c) measuring the level of UDP-galactose 4-epimerase polypeptide in the plant cell containing the recombinant DNA construct; (d) comparing the level of UDP-galactose 4-epimerase polypeptide in the plant cell containing the recombinant DNA construct with the level of UDP-galactose 4-epimerase polypeptide in a plant cell that does not contain the recombinant DNA construct; and (e) selecting for the isolated polynucleotide that reduces the level of expression of the UDP-galactose 4-epimerase polypeptide in the plant cell.
