| Abstract: | The major UDPG: flavonol glucosyltransferase (UFGT) in maize is an enzyme of strict positional specificity known to be coded by the Bz locus. In bz mature endosperms, no UFGT can be detected. However, bz embryos possess a residual flavonol glucosyltransferase activity which is independent of Bz locus control. The products of this activity have been identified as the 3′-, 7- and 3-glucosides. |
