Pathway Edits

  • PAR1 (phenylacetaldehyde reductase 1) downregulation to prevent phenylacetaldehyde reduction to 2-phenylethanol, maximizing aldehyde accumulation
  • PAAS (phenylacetaldehyde synthase / aromatic amino acid decarboxylase) overexpression for phenylalanine-to-phenylacetaldehyde one-step conversion in Brassica nigra
  • PAL downregulation in relevant tissue type to redirect phenylalanine from trans-cinnamic acid branch toward PAAS-mediated decarboxylative pathway
  • Phenylalanine aminomutase (PAM) modulation for phenylalanine pool management in PAAS-overexpression context

Key Interventions

PAAS overexpression with PAR1 downregulation establishes high-yield phenylacetaldehyde accumulation in Brassica nigra through one-step phenylalanine decarboxylationPAL-branch partial suppression and phenylalanine transporter upregulation maximize PAAS substrate supply for phenylacetaldehyde productionPhenylacetaldehyde TRPA1 agonism via aldehyde electrophilic Schiff base formation at TRPA1 Lys708 confirmed by IFI-P calcium-flux assayCell-free T7/SP6 translation system for in-vitro pungency pathway enzyme validation

Use Case

Tier II phenylacetaldehyde-enriched Brassica platform for rose-honey flavor notes with TRPA1 mildly pungent character, floral-pungent flavor ingredient production in confectionery and baked goods, and functional flavor applications where the distinctive phenylacetaldehyde floral warmth complements mustard-sulfur or spice-heat profiles in complex savory-sweet product formulations.
