Pathway Edits

  • SUS4 sucrose synthase isoform 4 overexpression for sucrose synthesis in Capsicum pericarp
  • SUS3 sucrose synthase isoform 3 co-expression for expanded sucrose biosynthetic capacity
  • SuSy sucrose synthase activity enhancement for increased sucrose accumulation in fruit tissue
  • INV-vac vacuolar invertase downregulation to prevent sucrose hydrolysis and maintain pool
  • SUT1 sugar transporter upregulation for phloem unloading and sink sucrose import enhancement

Key Interventions
