Pathway Edits

  • SlADSS adenylosuccinate synthase overexpression under CaMV35S promoter for de-novo IMP flux amplification via SAMP intermediate
  • SlADSL adenylosuccinate lyase upregulation for SAMP-to-AMP conversion acceleration, expanding purine pool feeding IMP via AMPD
  • SlHGPRT hypoxanthine-guanine phosphoribosyltransferase overexpression for salvage-pathway IMP recovery from hypoxanthine
  • SlIMPDH inosine monophosphate dehydrogenase partial RNAi knockdown (60%) to prevent IMP oxidation to XMP, preserving free IMP pool

Key Interventions

mGluR1 co-agonist IMP pool maximization via de-novo purine biosynthesis plus salvage pathway dual amplificationTAS1R1/TAS1R3 synergist IMP accumulation targeting 5′-nucleotide receptor binding site for maximum umami potentiationIMPDH blockade preserving IMP from oxidative diversion toward XMP/GMP branch
