Pathway Edits

  • PME overexpression (pectin methylesterase) for cell wall pectin demethylation and tannin association
  • PG1 upregulation (polygalacturonase 1) for pectin architecture remodeling
  • BAHD-GT glucosyltransferase amplification for polysaccharide-tannin linker formation
  • XTH co-expression (xyloglucan endotransglucosylase-hydrolase) for xyloglucan matrix optimization
  • Protoplast PEG-fusion transient and stable integration protocol
  • Enhanced flux via 5'UTR synthetic leader sequence optimization
