Pathway Edits

  • MYB14 transcription factor overexpression for stilbene and flavonoid network co-activation
  • MYB15 transcription factor amplification for synergistic MYB14 polyphenol network induction
  • LAR downstream target activation (leucoanthocyanidin reductase) for PA branch output
  • ANR downstream target upregulation (anthocyanidin reductase) for epicatechin PA branch
  • TT12 vacuolar transport upregulation for broad-spectrum polyphenol vacuolar sequestration
  • TT19 glutathione S-transferase overexpression for PA and flavonoid sequestration efficiency
  • AHA10 H+-ATPase activation for vacuolar acidification and polyphenol stability
  • Protoplast PEG-fusion transient and stable integration protocol
  • Enhanced flux via 5'UTR synthetic leader sequence optimization
