Pathway Edits

  • GmADSS adenylosuccinate synthase overexpression for elevated IMP via de-novo purine pathway in Glycine max seed tissue
  • GmIMPDH2 inosine monophosphate dehydrogenase balanced overexpression for IMP/GMP co-accumulation without net IMP depletion
  • GmGMPS GMP synthase activity tuned to 60% of IMPDH output to maintain 1.7:1 IMP:GMP ratio for maximum synergy
  • GmADSL adenylosuccinate lyase upregulation ensuring AMP/IMP cycling prevents adenylate deficiency during IMP accumulation phase
  • GmNT5C 5′-nucleotidase expression calibrated via synthetic promoter strength to maintain free nucleotide fraction over phosphorylated forms
  • GmPNP purine nucleoside phosphorylase isoform 2 overexpression for nucleoside salvage amplification across IMP and GMP branches
  • GmGDH glutamate dehydrogenase upregulation for co-production of free glutamate to enhance nucleotide synergy via triple co-agonism
  • GmAMPD AMP deaminase partial knockdown (40%) to prevent IMP loss via adenylate catabolism during seed maturation

Key Interventions

Synergistic 5′-IMP + 5′-GMP co-accumulation at optimized 1.7:1 ratio for maximum mGluR1 and TAS1R1/TAS1R3 receptor co-activationTriple co-agonism via IMP + GMP + free glutamate co-engineering for IFI-U score multiplication beyond individual nucleotide effectsPurine pathway flux balancing preventing adenylate pool depletion while sustaining maximal IMP/GMP steady-state concentrations
