Pathway Edits
- SG4 overexpression (sorghum flavan-4-ol synthase) for phlobaphene precursor production
- LAR co-expression (leucoanthocyanidin reductase) for PA branch balance modulation
- ANR upregulation (anthocyanidin reductase) to modulate phlobaphene:PA ratio
- F3H amplification (flavanone 3-hydroxylase) for dihydroflavonol substrate supply
- CHS enhancement (chalcone synthase) for naringenin-based substrate pool expansion
- Cell-free wheat germ extract reconstitution system
