Pathway Edits

SlGAD1 glutamate decarboxylase isoform 1 overexpression under fruit-ripening promoter for GABA accumulation from free glutamate in ripening tomato pericarp
SlGAD2 isoform 2 co-overexpression via bidirectional promoter for expanded GABA biosynthesis capacity across fruit development stages
SlGABA-T GABA transaminase RNAi knockdown (70%) to block GABA catabolism to succinate-semialdehyde, preserving GABA pool for mGluR1 modulation
SlSSADH succinate-semialdehyde dehydrogenase partial suppression (40%) to slow downstream GABA shunt flux without TCA cycle impairment

Key Interventions

GABA mGluR1 allosteric modulation via GAD1/GAD2 upregulation and GABA-T suppression for sustained GABA pool in tomato fruitVacuolar GABA compartmentalization via VAT overexpression for processing-triggered release and mGluR1 activation in food matrixGABA-glutamate balance engineering preventing glutamate depletion while maximizing GABA accumulation for dual mGluR1 signaling
