Pathway Edits

SlGAME1 glycoalkaloid metabolism 1 RNAi knockdown (75%) to suppress alpha-tomatine biosynthesis and reveal latent savory character in ripening fruit
SlGAME4 steroidal alkaloid gamma-solanine methyltransferase RNAi suppression (60%) to block upper tomatine pathway flux complementing GAME1 knockdown
SlGDH2 glutamate dehydrogenase isoform 2 upregulation for net free glutamate elevation simultaneously with tomatine removal for compounded umami enhancement

Key Interventions

Alpha-tomatine bittering compound removal via GAME1/GAME4 RNAi for unmasking latent mGluR1 umami signal in tomato fruitGDH2 free glutamate elevation co-engineered with tomatine suppression for compounded umami intensity in finished productLOX1 off-note suppression for clean flavor unmasking after tomatine removal, ensuring revealed umami is not accompanied by aldehyde artifacts
