Pathway Edits
- LAR balanced expression (leucoanthocyanidin reductase) for catechin starter unit control
- ANR high-flux variant (anthocyanidin reductase) for epicatechin extension unit dominance
- DFR-EC epicatechin-favoring dihydroflavonol 4-reductase allele overexpression
- F3H substrate channeling (flavanone 3-hydroxylase) for dihydroquercetin precursor flux
- TT12 vacuolar transport for procyanidin structure-preserving sequestration
- Cell-free wheat germ extract reconstitution system
- Enhanced flux via 5'UTR synthetic leader sequence optimization
