Patent ID: 7009087

Claim:
A method for altering the disulfide status of storage proteins in a plant or part thereof, said method comprising transforming said plant with a first nucleotide construct comprising a first nucleotide sequence and a second nucleotide construct comprising a second nucleotide sequence, wherein said first nucleotide sequence encodes an NADPH-thioredoxin reductase, said second nucleotide sequence encodes a thioredoxin h, and said first nucleotide sequence is selected from the group consisting of: a) the nucleotide sequence set forth in SEQ ID NO: 24; b) a nucleotide sequence encoding the amino acid sequence set forth in SEQ ID NO: 25; c) a nucleotide sequence having at least 95% sequence identity to the coding sequence of the nucleotide sequence set forth in SEQ ID NO: 24, wherein said nucleotide sequence encodes a polypeptide comprising NADPH-thioredoxin reductase activity; d) a nucleotide sequence that hybridizes under stringent conditions to the complement of the nucleotide sequence set forth in SEQ ID NO: 24, wherein said nucleotide sequence encodes a polypeptide comprising NADPH-thioredoxin reductase activity, and wherein said stringent conditions comprise hybridization at 37° C. in a solution comprising in 50% formamide, 1 M NaCl, and 1% SDS, and at least one wash at 60° C. in a solution comprising 0.1×SSC; and e) a nucleotide sequence that is complementary to the nucleotide sequence or a), b), c), or d); wherein said disulfide status of said storage proteins is decreased in said plant or part thereof.
