Pathway Edits

  • ANS overexpression (anthocyanidin synthase) for parallel anthocyanin formation
  • UFGT amplification (UDP-glucose flavonoid 3-O-glucosyltransferase) for anthocyanin glycosylation
  • LAR co-activation (leucoanthocyanidin reductase) for proanthocyanidin branch supply
  • ANR upregulation (anthocyanidin reductase) for epicatechin PA extension units
  • TT12 vacuolar transport for co-localization of tannin and anthocyanin in vacuole
  • T-DNA right-border optimized integration cassette
