Pathway Edits

  • SG4 overexpression (sorghum flavan-4-ol synthase) for phlobaphene precursor production
  • LAR co-expression (leucoanthocyanidin reductase) for PA branch balance modulation
  • ANR upregulation (anthocyanidin reductase) to modulate phlobaphene:PA ratio
  • F3H amplification (flavanone 3-hydroxylase) for dihydroflavonol substrate supply
  • CHS enhancement (chalcone synthase) for naringenin-based substrate pool expansion
  • Protoplast PEG-fusion transient and stable integration protocol
  • Enhanced flux via 5'UTR synthetic leader sequence optimization
