Pathway Edits

  • SlASNS1 asparagine synthetase 1 partial suppression (55% via amiRNA) to reduce glutamine diversion to asparagine, freeing glutamine for GS-GOGAT glutamate cycling
  • SlASP4 aspartate 4-hydroxylase RNAi knockdown to block asparagine catabolism to succinate, redirecting aspartate toward glutamate via AAT2
  • SlGDH glutamate dehydrogenase overexpression for enhanced reductive amination of alpha-ketoglutarate to glutamate under accumulated ammonium from ASNS suppression
  • SlAAT2 aspartate aminotransferase isoform 2 upregulation for enhanced aspartate-to-oxaloacetate transamination freeing glutamate equivalents
  • SlNSP asparagine peptide hydrolase overexpression to liberate free asparagine from peptide pools for downstream ASN-to-GLU conversion

Key Interventions

ASN-to-GLU pathway re-routing via ASNS1 suppression and GDH/AAT2 upregulation for net free glutamate accumulation in ripening tomatoNitrogen recycling engineering capturing asparagine amide nitrogen into glutamate pool for mGluR1 direct agonismAspartate-to-glutamate carbon routing via AAT2 for complementary free amino acid pool conversion supporting umami intensity
