Pathway Edits

  • F6H1 feruloyl-CoA 6'-hydroxylase RNAi blocks scopoletin-to-coumarin lactone conversion
  • CYP98A caffeic acid 3-O-methyltransferase modification reduces feruloyl substrate availability for the coumarin branch
  • scopoletin-GT glucosyltransferase overexpression stabilizes scopoletin as non-bitter scopolin glucoside
