Pathway Edits

  • SlGDH1 promoter swap to CaMV35S for constitutive glutamate dehydrogenase expression
  • SlGOGAT upregulation via synthetic fruit-ripening promoter for enhanced glutamine:2-oxoglutarate aminotransferase activity
  • Vacuolar glutamate transporter SlVGT1 overexpression for apoplastic glutamate accumulation
  • SlGS2 activity boost via T-DNA insertion at native locus for plastidic glutamine synthetase amplification
  • SlAAT1 aspartate aminotransferase redirected to favor glutamate over aspartate production
  • Feedback-resistant SlGS1 cytosolic isoform introduced for unregulated glutamate synthesis
  • SlGln1;2 pericarp-specific overexpression for localized free amino acid enrichment

Key Interventions

TAS1R1/TAS1R3 binding-site glutamate pool expansion via GDH/GS dual upregulationGlutamate vacuolar compartmentalization for controlled release during tissue disruptionmGluR1 sensitization via reduced competing amino acid background
