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
Protoplast PEG-fusion transient and stable integration protocol
Enhanced flux via 5'UTR synthetic leader sequence optimization
