Pathway Edits

  • S6PDH sorbitol-6-phosphate dehydrogenase overexpression for direct conversion of glucose-6-P to sorbitol
  • SDH sorbitol dehydrogenase downregulation to prevent catabolism of accumulated sorbitol
  • SPS sucrose phosphate synthase activity optimization for sucrose-sorbitol metabolic balance
  • SPP sucrose phosphate phosphatase co-expression for enhanced sucrose-to-sorbitol flux management
  • Fructokinase activity suppression to redirect fructose toward the sorbitol biosynthetic route
  • Vacuolar H+-ATPase upregulation for enhanced sorbitol compartmentalization in sugarcane
  • SWEET transporter expression for optimized sorbitol loading into phloem and sink tissues

Key Interventions

S6PDH overexpression for direct glucose-6-phosphate conversion to sorbitol in sugarcaneSDH downregulation preventing sorbitol catabolism to maintain high steady-state accumulationSPS co-optimization balancing sucrose-sorbitol carbon partitioning for desired sweetness profile
