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
  • SlPurA GMP reductase variant introduction to redirect GMP back to IMP under nucleotide surplus conditions
  • SlXMP accumulation suppressed via SlGMPS guanosine monophosphate synthase down-regulation, reducing IMP diversion to GMP branch
  • SlNT5C 5′-nucleotidase overexpression for enhanced IMP dephosphorylation and re-phosphorylation cycling to elevate free IMP steady state
