Pathway Edits
- LAR-short overexpression (truncated leucoanthocyanidin reductase variant) for low-DP catechin unit production
- ANR-low expression (low-activity anthocyanidin reductase) to limit PA chain elongation
- TT12-alt alternative vacuolar transporter preferentially sequesters short-chain PAs for smooth-finish accumulation
- Cell-free wheat germ extract reconstitution system
Key Interventions
LAR-short truncation for low-DP catechin unit supply limiting proanthocyanidin chain elongationANR-low activity attenuation for reduced epicatechin extension and short PA distributionTT12-alt selective vacuolar transport for smooth-finish low-MW proanthocyanidin accumulationSP6/T7 dual-polymerase cell-free transcription/translation
