Pathway Edits

  • F3-5H overexpression (flavonoid 3',5'-hydroxylase) for 3,5-dihydroxyl ring B substitution
  • F3H upregulation (flavanone 3-hydroxylase) for dihydromyricetin precursor supply
  • ANR co-activation (anthocyanidin reductase) for gallocatechin extension unit formation
  • LAR alternative allele for leucodelphinidin reductase activity toward gallocatechin
  • DFR-alt selection for leucodelphinidin substrate preference over leucocyanidin
  • Protoplast PEG-fusion transient and stable integration protocol

Key Interventions
