Pathway Edits

  • GmGCL gamma-glutamylcysteine ligase overexpression under seed-specific promoter for glutathione accumulation as CaSR-activating gamma-glutamyl peptide in soy
  • GmGS glutathione synthase upregulation for complete GSH synthesis from GCL product, enabling triple gamma-glutamyl peptide pool formation
  • GmGDH2 glutamate dehydrogenase isoform 2 overexpression for free glutamate co-accumulation ensuring mGluR1 direct agonism alongside CaSR kokumi activity
  • GmGGT gamma-glutamyltransferase upregulation for gamma-Glu-Val-Gly tripeptide synthesis as potent CaSR agonist from GSH pool
  • GmGLN1 glutamine synthetase cytosolic isoform overexpression for sustained glutamine supply to both GCL and GOGAT pathways
  • GmGSR glutathione reductase upregulation for GSSG recycling maintaining reduced GSH pool available for gamma-glutamyl transfer
  • GmPCS phytochelatin synthase partial suppression to prevent GSH diversion into phytochelatin synthesis during metal stress
