Pathway Edits

CcGS1 overexpression under pericarp-specific Cc2A11 promoter for compartment-targeted glutamine synthetase boost
CcGDH2 allosteric tuning via N-terminal domain truncation for higher Vmax without ADP inhibition
GABA shunt suppression via CcSSADH partial RNAi knockdown to redirect succinate-semialdehyde back to glutamate
Vacuolar H+-ATPase CcVHA-A subunit upregulation for enhanced glutamate compartmentalization driving cytosolic replenishment
Feedback-resistant CcGLN1 mutant (G297A, R299K) for glutamine synthetase desensitization to glutamine product inhibition

Key Interventions

Free amino acid pool redirection from GABA and alanine pathways toward net glutamate accumulationTAS1R1/TAS1R3 co-agonist enhancement via IMP co-accumulation through purine salvage pathway modulationSynergistic IMP/GMP co-enrichment via nucleotide transporter upregulation
