The development of a cell-substrate attachment system in a euglenoid flagellate.

摘要: The transition of the euglenoid Colacium libellae from free-swimming flagellated to nonflagellated stage attached by a stalk occurs in three distinct stages: (1) initial attachment, perhaps flagellum, (2) substrage contact anterior region cell concomitant with attachment disc formation, and (3) extrusion material. flagellum is resorbed within minutes attachment. Polysaccharide acid phosphatase derived intracellular cisternae initially accumulate reservoir, then transfer canal finally become incorporated into stalk, thus delineating source routte transport for most Indeed, inner “shaft” central “core” contain neutral polysaccharide that continuous similar material found reservoir canal. peripheral (the “cortex”), however, contains polyanionic which may be extruded special secretory system composed ring granules canals located beneth pellicle organism.
