This invention relates to an isolated polynucleotide encoding an aldehyde reductase enzyme. The invention also relates to the construction of a recombinant construct encoding an aldehyde reductase enzyme wherein expression of the recombinant construct results in production of altered levels of aldehyde reductase enzyme in a transformed host cell. The present invention also concerns soybean products made from seeds obtained from soybean plants transformed with this recombinant construct wherein such seeds having increased aldehyde reductase activity.
