Pathway Edits

  • SlGOGAT1 NADH-dependent glutamate synthase isoform 1 overexpression under fruit-ripening MADS-box RIN promoter for pericarp-specific GS-GOGAT cycle amplification
  • SlGS2 plastidic glutamine synthetase upregulation via dual 35S promoter for chloroplast glutamine synthetase expansion supporting GOGAT substrate supply
  • SlFd-GOGAT ferredoxin-dependent GOGAT chloroplast isoform overexpression for photosynthetically driven glutamate synthesis complementing NADH-GOGAT
  • SlGDH glutamate dehydrogenase overexpression as overflow safety valve ensuring excess ammonium is channeled into glutamate rather than GABA or free ammonia

Key Interventions

GS-GOGAT cycle optimization via GOGAT1/GS2/Fd-GOGAT triple upregulation for maximum net glutamate export in tomato pericarpNitrogen assimilation amplification through NiR/NR upregulation ensuring substrate supply to GS-GOGAT glutamate synthesis cycleOverflow GDH expression preventing ammonium accumulation and directing excess nitrogen into glutamate mGluR1 agonist pool
