Cellulase activity was localized at the ultrastructural level in the articulated, anastomosing laticifers of Papaver somniferum. Electron‐dense crystalline deposits indicating the presence of cellulase activity were restricted to discrete patches along the laticifer wall in regions of recently formed perforations. This report presents the first direct evidence for the involvement of cellulases in the cell wall perforation process in articulated laticifers.
