  • volatile sulfur flavour compound biosynthesis;
  • flavours as secondary metabolites;
  • secondary metabolite biosynthesis - of highly organized and controlled process;
  • compounds, dispensable or ‘secondary’ - biological and ecological functions;
  • sulfur, important macronutrient in plant biology - component of housekeeping biomolecules;
  • sulfur compounds as flavour volatiles;
  • alk(en)yl cysteine sulfoxide flavour precursors;
  • enzyme lachrymatory factor synthase;
  • volatile GS hydrolysis product release;
  • hydrogen sulfide (H2S), major reduced sulfur compound - released by plants, origin uncertain
