Abstract
The existence of an enzymatic activity catalyzing the NADPH-dependent reduction of (+)-dihydroquercetin to (+)-2,3-trans-3,4-cis-leucocyanidin in crude extracts of wild type Zea mays is described. Expression of this dihydroquercetin reductase (DQR) activity depends on the genotype of mutants for anthocyanin biosynthesis. Protein translated in vitro from the RNA product of a full-length A1 cDNA clone exhibits DQR activity; therefore, the A1 locus is the structural gene for DQR of maize.
