Pathway Edits

GSTU20 (glutathione S-transferase) upregulation for glucoerucin biosynthesis and TRPA1-active erucin formation
MAM3 (methylthioalkylmalate synthase 3) overexpression for 4-methylthiobutyl glucosinolate chain elongation
CYP79F1 upregulation for long-chain aliphatic glucosinolate oxime synthesis from homomethionine
FMOGS-OX1-null allele introduction to prevent glucoerucin oxidation to sulforaphane-analog branch

Key Interventions

MAM3/CYP79F1 chain-elongation pathway amplification for glucoerucin pool expansion in Brassica nigraFMOGS-OX1-null allele preserves glucoerucin in the reduced thioether form for selective erucin ITC formation via TGG1 myrosinaseErucin TRPA1 electrophilic agonism confirmed by IFI-P calcium-flux assay; erucin isothiocyanate targets TRPA1 Cys621 for covalent channel activationPEG-mediated transient expression protocol validated for rapid phenotypic pathway screening

Use Case

Tier II erucin-enriched Brassica platform for sulfurous-ITC flavor applications in mustard condiments, cooked brassica flavor development, and TRPA1-selective functional ingredient production where erucin's milder, less volatile profile relative to AITC is preferred for thermal stability in hot-processed food applications.
