Pathway Edits

ANS overexpression (anthocyanidin synthase) for parallel anthocyanin formation
UFGT amplification (UDP-glucose flavonoid 3-O-glucosyltransferase) for anthocyanin glycosylation
LAR co-activation (leucoanthocyanidin reductase) for proanthocyanidin branch supply
ANR upregulation (anthocyanidin reductase) for epicatechin PA extension units
TT12 vacuolar transport for co-localization of tannin and anthocyanin in vacuole
T-DNA right-border optimized integration cassette
Enhanced flux via 5'UTR synthetic leader sequence optimization
