Abstract

Analysis of mesophyll protoplasts and cell wall extracts of leaf discs of Costa Rican wild lima bean (Phaseolus lunatus L.) shows that the linamarase activity is confined to the apoplast. Its substrate linamarin, together with the related enzyme hydroxynitrile lyase, is found inside the cells. This compartmentation prevents cyanogenesis from occurring in intact tissue, and suggests that linamarin has to be protected during any translocation across the linamarase rich apoplast.
