Pathway Edits

  • FLS1 overexpression (flavonol synthase 1) for quercetin and myricetin production
  • F3H upregulation (flavanone 3-hydroxylase) for dihydroquercetin precursor supply
  • F3-5H co-expression for myricetin branch from dihydromyricetin
  • CHS amplification (chalcone synthase) for naringenin chalcone substrate expansion
  • CHI enhancement (chalcone isomerase) for naringenin isomerization efficiency
  • Protoplast PEG-fusion transient and stable integration protocol
  • Enhanced flux via 5'UTR synthetic leader sequence optimization

Key Interventions

FLS1 diversion of dihydroflavonol intermediates toward quercetin/myricetin accumulationCHS/CHI substrate pool expansion for elevated flavonol precursor availabilityF3-5H hydroxylation for myricetin enrichment alongside quercetin productionPEG-4000 mediated membrane fusion at 37°CVariant B enhanced: iterative codon optimization for host-matched expression
