Pathway Edits

  • SPDS (spermidine synthase) overexpression cassette for direct spermidine biosynthesis amplification
  • ADC (arginine decarboxylase) expression for agmatine-to-putrescine pathway activation
  • ODC (ornithine decarboxylase) activity enhancement for putrescine precursor supply
  • SAMDC (S-adenosylmethionine decarboxylase) overexpression for aminopropyl donor availability
  • PAO (polyamine oxidase) silencing to block spermidine retroconversion to putrescine
  • Spermidine vacuolar export transporter upregulation for cytosolic accumulation

Key Interventions

SPDS overexpression for direct spermidine biosynthesis as CaSR polyamine ligand in AlliumADC/ODC dual-pathway activation for high-flux putrescine supply to SPDS spermidine synthesisPAO retroconversion silencing to prevent spermidine catabolism and maximize steady-state poolProtoplast PEG-fusion delivery optimized for Allium sativum genome accessibilityTier-IV construct validated with 6 precision edits for 2.38× fold-change
