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. plant tissue colonization biological_process Do not confuse with ' GO:0036267 invasive filamentous growth ', which doesn't include invasion of cells within the host.
