Pathway Edits

F3-5H overexpression (flavonoid 3',5'-hydroxylase) for 3,5-dihydroxyl ring B substitution
F3H upregulation (flavanone 3-hydroxylase) for dihydromyricetin precursor supply
ANR co-activation (anthocyanidin reductase) for gallocatechin extension unit formation
LAR alternative allele for leucodelphinidin reductase activity toward gallocatechin
DFR-alt selection for leucodelphinidin substrate preference over leucocyanidin
Protoplast PEG-fusion transient and stable integration protocol
Enhanced flux via 5'UTR synthetic leader sequence optimization
