Pathway Edits
- ANR anthocyanidin reductase RNAi reduces catechin/epicatechin extension units available for tannin polymerization
- TT12 tonoplast multidrug transporter RNAi impairs vacuolar sequestration and stabilization of condensed tannins
- LAR leucoanthocyanidin reductase RNAi reduces (+)-catechin monomer supply for proanthocyanidin polymerization

Use Case
Tier I Vitis vinifera lines with reduced condensed tannin load for palatable table grape production, low-astringency wine varieties, and grape-derived polyphenol extracts where TAS2R activation is undesirable.
