Influence of B and Pl on UDPG:Flavonoid-3-O-glucosyltransferase in Zea mays L

Biochem Genet. 1984 Dec;22(11-12):1161-9. doi: 10.1007/BF00499639.

Abstract

The influence of the genetic constitution at the B and Pl loci on UDPG:flavonoid-3-O-glucosyltransferase activity is described. More than a 90% reduction in activity is found when either B or Pl was present in the homozygous recessive condition. A positive correlation between quercetin-3-O-glucoside and pelargonidin-3-O-glucoside production is observed for all genotypes tested. Changes in UFGT activity during plant development are described for R-r B Pl plants.
