| description | The directional movement of a hyphal filament from one host cell to another. This process involves the clearance of plant-derived plasmodesmal occlusion materials, cytoskeleton based constriction of invasive hypha to traverse plasmodesmata. Septins and F-actin are reorganized into an hourglass shape at the point of maximum hyphal constriction. |
