Pathway Edits

  • LAR balanced expression (leucoanthocyanidin reductase) for procyanidin catechin unit topology
  • ANR tuning (anthocyanidin reductase) for epicatechin extension unit frequency
  • TT12 vacuolar transport for procyanidin structure-preserving sequestration
  • TT19 glutathione S-transferase for PA sequestration efficiency optimization
  • LDOX co-expression (leucoanthocyanidin dioxygenase) for structural feature modulation of condensed tannin
  • Protoplast PEG-fusion transient and stable integration protocol
