Pathway Edits

  • LAR balanced expression (leucoanthocyanidin reductase) for catechin starter unit control
  • ANR high-flux variant (anthocyanidin reductase) for epicatechin extension unit dominance
  • DFR-EC epicatechin-favoring dihydroflavonol 4-reductase allele overexpression
  • F3H substrate channeling (flavanone 3-hydroxylase) for dihydroquercetin precursor flux
  • TT12 vacuolar transport for procyanidin structure-preserving sequestration
  • Biolistic tungsten-particle coating for leaf/seed explant delivery
