Pathway Edits

  • UGT91D2 expression cassette for multi-glucosylation of RebD intermediate to rebaudioside M
  • UGT40 upregulation for the final C-3' glucosylation step in RebM biosynthesis
  • UGT76G1 co-expression to maintain upstream RebA and RebD intermediate supply
  • UGT74G1 expression enhancement for complete C-19 glucosylation toward RebM precursors
  • CDPG co-expression for enhanced ent-copalyl diphosphate precursor availability
  • Antisense UGT85C2 element suppressing stevioside diversion and maximizing RebM-directed flux
  • RebD intermediate stabilization via transient vacuolar targeting signal deletion

Key Interventions

UGT91D2 and UGT40 dual overexpression for complete RebM multi-glucosylation cascadeUGT76G1 co-expression maintaining upstream RebA and RebD intermediate fluxStevioside diversion pathway suppression to maximize RebM-directed carbon flow
