Pathway Edits

  • DFR-alt overexpression (3',5'-dihydroxyl-preferring dihydroflavonol 4-reductase allele)
  • F3-5H upregulation for B-ring trihydroxylation toward leucodelphinidin branch
  • ANS-KO (anthocyanidin synthase knockout) to block leucodelphinidin conversion to delphinidin
  • LAR-alt co-expression (alternative LAR allele with leucodelphinidin substrate preference)
  • Biolistic tungsten-particle coating for leaf/seed explant delivery
  • Enhanced flux via 5'UTR synthetic leader sequence optimization
