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)
- Cell-free wheat germ extract reconstitution system
- Enhanced flux via 5'UTR synthetic leader sequence optimization
