Abstract

This invention relates to an isolated nucleic acid fragment encoding soybean enzymes that catalyze steps in biosynthesis of isoflavones, the enzyme a member selected from the group consisting of chalcone isomerase, isoflavone reductase and vestitone reductase. The invention also relates to the construction of chimeric genes encoding all or a substantial portion of the enzymes, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the enzyme in a transformed host cell.
