Genetic control of UDPglucose:flavonol 3-O-glucosyltransferase in the endosperm of maize

H K Dooner et al. Biochem Genet. 1977 Jun.

Abstract

The enzyme UDPglucose:flavonol 3-O-glucosyltransferase is shown to be under the coordinate control of three genes involved in anthocyanin biosynthesis in the aleurone of maize: C, R, and BZ. Of the three, BZ appears to be the structural gene. Data presented here (dosage comparisons, induction in the mutant c-p, and effect of paramutation at R) indicate that the enzyme is inducible by substances resulting from the action of the C and R genes and that active forms of C and R are required for this induction. Mechanisms of regulation of the BZ gene by C and R are discussed.
