Pathway Edits

  • DXMT 3,7-dimethylxanthine N-methyltransferase RNAi blocks final methylation converting theobromine to caffeine
  • TCSAMT 7-methylxanthine N-methyltransferase RNAi reduces theobromine-to-caffeine conversion efficiency
  • CS caffeine synthase partial antisense reduces overall N-methylation capacity in young leaves
  • XDH xanthine dehydrogenase engineering redirects xanthine oxidation away from the methylation pathway

Use Case

Tier V Camellia sinensis lines for naturally low-caffeine tea production, decaffeinated specialty tea formulations, and pediatric or sensitive-population beverage applications where methylxanthine content must be strictly controlled without solvent-based decaffeination.
