Pathway Edits

  • UGT76G1 overexpression via strong 35S promoter for C-13 stevioside glucosylation
  • UGT74G1 upregulation for C-19 glucosylation step completion toward rebaudioside A
  • DXS overexpression to enhance MEP pathway flux into IPP and DMAPP precursors
  • KAH cytochrome P450 optimization for improved ent-kaurenoic acid hydroxylation efficiency
  • CDPG co-expression for ent-copalyl diphosphate precursor amplification
  • KO upregulation for ent-kaurene oxidation step enhancement toward steviol
  • RNAi cassette suppressing stevioside diversion pathway to maximize RebA-directed flux

Key Interventions
