Pathway Edits

  • LAR upregulation (leucoanthocyanidin reductase) for catechin starter unit supply
  • ANR co-activation (anthocyanidin reductase) for epicatechin extension units
  • TT12 vacuolar flavonoid transporter amplification
  • TT19 glutathione S-transferase overexpression for PA vacuolar sequestration
  • AHA10 H+-ATPase enhancement for vacuolar acidification and tannin stability
  • Biolistic tungsten-particle coating for leaf/seed explant delivery

Key Interventions
