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
- SlTOMA1 tomatidine acetyltransferase heterologous suppression to prevent tomatidine acetylation and shift any residual alkaloid toward inactive forms
- SlUGT steroidal glycosyltransferase UGT73P2 directed-evolution variant for rapid tomatine glycosylation and sequestration in vacuoles, clearing active pool
- SlGS1 cytosolic glutamine synthetase upregulation for sustained glutamine-to-glutamate cycling complementing GDH2-driven free glutamate increase
- SlLox1 lipoxygenase 1 partial knockdown to reduce hexanal/nonenal off-notes unmasked by tomatine removal, cleanly revealing umami character
