    Hydroxynitrile glucosides (HNGs) are present in many plant species. Barley (Hordeum vulgare L.) contains five HNGs which are biosynthesized in the mesophyll and accumulated in the epidermal cells. The transport mechanisms will be investigated. HNGs are often found to be cyanogenic and by herbivore or pathogen attack, hydrogen cyanide is released. The enzyme required for this reaction is not present in barley, challenging the function of barley HNGs as defense compounds. The barley powdery mildew Blumeria graminis f.sp. hordei strictly infects the cells where the compounds are accumulated. This interaction is used to study the potential role of barley HNGs in chemical defense.
