Pathway Edits

  • CsCSHD cystathionine gamma-synthase homolog overexpression for enhanced L-theanine biosynthesis via glutamate-ethylamine condensation in young tea leaves
  • CsGDH glutamate dehydrogenase upregulation under CaMV35S for increased glutamate substrate availability feeding theanine synthase reaction
  • CsTSII theanine synthase isoform II overexpression for expanded glutamate-to-theanine conversion capacity in mesophyll cells
  • CsTDH theanine demethylase activity suppression via RNAi to prevent L-theanine catabolism to glutamate + ethylamine
  • CsATP-binding cassette transporter upregulation for vacuolar L-theanine accumulation and controlled release during tea processing

Key Interventions

L-theanine mGluR1 positive allosteric modulation engineering via CSDH/TSII dual upregulation for elevated tea umami characterGlutamate substrate pool maintenance ensuring theanine synthesis does not deplete free glutamate mGluR1 agonist poolmGluR1 PAM (positive allosteric modulator) concentration maximization in young leaf tissue for premium green tea umami intensity
