Abstract
Two separate genes, Fg and Vg, which govern the presence of isovitexin 2″-O-glucoside and vitexin 2″-O-glucoside respectively in the petals of Silene alba control different glucosyltransferases. In Vg/Vg,fg/fg plants no isovitexin 2″-O-glucosyltransferase was present and in vg/vg,Fg/Fg plants no vitexin 2″-O-glucosyltransferase activity could be detected. The Fg-controlled UDP-glucose: isovitexin 2″-O-glucosyltransferase
