Pathway Edits

  • SG4-RNAi silencing (sorghum flavan-4-ol synthase RNAi) for phlobaphene/PA precursor suppression
  • ANR-RNAi knockdown (anthocyanidin reductase RNAi) for epicatechin extension unit depletion
  • TT19-RNAi suppression (vacuolar transport RNAi) for PA sequestration efficiency reduction
  • Protoplast PEG-fusion transient and stable integration protocol
  • Enhanced flux via 5'UTR synthetic leader sequence optimization
