Pathway Edits

  • LOX2 (lipoxygenase 2) upregulation for C18-fatty acid hydroperoxide formation in Nasturtium officinale leaf tissue
  • HYDROLYASE (fatty acid hydroperoxide hydrolyase) engineering for C3-volatile aldehyde cleavage product yield optimization
  • FAD (fatty acid desaturase) activity modulation for linolenic acid C18:3 substrate enrichment as LOX2 input
  • AOS (allene oxide synthase) partial knockdown to redirect FA hydroperoxide flux toward hydrolyase-mediated volatile pathway
  • Aldehyde dehydrogenase (ALDH) suppression in relevant cell types to prevent acrolein-analog oxidation to non-volatile acid

Key Interventions

LOX2/HYDROLYASE cascade optimization for controlled C3-volatile aldehyde accumulation in Nasturtium officinale via linolenic acid oxidationAOS partial knockdown redirects fatty acid hydroperoxide flux from jasmonate pathway toward hydrolyase-mediated volatile pungent aldehyde formationAcrolein-analog TRPA1 volatile aldehyde agonism confirmed by IFI-P calcium-flux assay; mild irritating pungency characteristic of green-volatile leaf volatiles validated in panelBiolistic bombardment parameters optimized for high-copy tandem stable integration events

Use Case

Tier IV acrolein-analog volatile platform for green-pungent flavor notes in Nasturtium-based condiments, watercress-flavor ingredient standardization, and low-intensity TRPA1 aldehyde activation in fresh salad dressings and cold-process sauces requiring the characteristic peppery-green sharpness of Nasturtium at calibrated sub-irritant concentrations verified by IFI-P panel scoring.
