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
