Pathway Edits

  • ANR differential expression (anthocyanidin reductase) for epicatechin flux control
  • LAR allelic balancing (leucoanthocyanidin reductase) for catechin:epicatechin ratio
  • F3-5H overexpression (flavonoid 3',5'-hydroxylase) for gallated catechin precursor enrichment
  • DFR allelic selection for 3',4'- vs 3',4',5'-dihydroxyl substrate preference
  • FLS suppression (flavonol synthase) to redirect dihydroflavonol flux toward catechins
  • Protoplast PEG-fusion transient and stable integration protocol
