Pathway Edits

  • GAD1 (glutamate decarboxylase 1) overexpression cassette for high-flux GABA biosynthesis
  • GAD2 isoform co-expression for redundant GABA production under varied pH conditions
  • SSADH-RNAi (succinate semialdehyde dehydrogenase) silencing to block GABA catabolism
  • POP2 (pollen-pistil incompatibility 2) GABA transaminase attenuation via RNAi
  • GABA permease upregulation for cytosolic GABA pool accumulation and export
  • PYR/PYL ABA receptor modulation to relieve GAD1 inhibitory phosphorylation

Key Interventions

GAD1/GAD2 co-expression for redundant high-flux GABA biosynthesis from glutamate in CapsicumSSADH and POP2 dual silencing to prevent GABA catabolism and maximize steady-state poolGABA permease upregulation for cytosolic and extracellular CaSR allosteric modulator accumulationProtoplast PEG-fusion delivery optimized for Capsicum annuum genome accessibilityTier-IV construct validated with 7 precision edits for 2.75× fold-change
