Pathway Edits

  • ANR anthocyanidin reductase RNAi shifts flavan-3-ol flux away from EGCG accumulation
  • LAR leucoanthocyanidin reductase RNAi reduces catechin/epicatechin precursor pool for galloylation
  • F3H flavanone 3-hydroxylase modification limits dihydroflavonol substrate for catechin entry
  • DFR dihydroflavonol 4-reductase engineering reduces anthocyanidin branch competition pressure
