Pathway Edits
- SlGDH2 glutamate dehydrogenase isoform 2 overexpression under fruit-ripening RIN promoter for TCA-to-glutamate reductive amination burst at red stage
- SlGS1 cytosolic glutamine synthetase feedback-resistant mutant (G295A) for unregulated glutamine-to-glutamate cycling under high-nitrogen conditions
- SlGOGAT glutamine:2-oxoglutarate aminotransferase upregulation for expanded GS-GOGAT cycle flux amplifying net free glutamate output
- SlGLN1;2 pericarp-specific glutamine synthetase overexpression for localized free amino acid accumulation in fruit skin
- SlAAT aspartate aminotransferase isoform 1 redirected via active-site mutation (K256R) favoring glutamate over aspartate output
- SlVGT1 vacuolar glutamate transporter overexpression for apoplastic glutamate accumulation and controlled release upon maceration
