Pathway Edits
- SG4 RNAi suppresses phlobaphene polymerization from flavan-4-ol units in epidermal cells
- LAR leucoanthocyanidin reductase modification reduces flavan-3,4-diol substrate availability for SG4
- ANR RNAi silencing limits anthocyanidin precursor flux that feeds the phlobaphene branch
- TT12 tonoplast transporter RNAi reduces phlobaphene sequestration and vacuolar stabilization

Use Case
Tier II Brassica oleracea lines with reduced phlobaphene content for applications requiring clean flavor profiles in cooked Brassica products, dehydrated vegetable powders, and functional ingredient lines where off-color and bitter tannin co-presence is penalized.
