摘要

The inner periplast component (IPC) of numerous cryptomonads is composed of discrete inner plates, situated beneath (and intimately associated with) the plasma membrane (PM). Freeze-fracture images reveal that the PM is organized into a series of ordered structural domains, which directly correspond in size and shape to the underlying inner plates. Freeze-fracture images are used here to compare IPC arrangement in Rhinomonas pauca, Proteomonas sulcata [haplomorph], Rhodomonas baltica, and Cryptomonas ovata, and to examine development of inner plates in these cryptomonads. In all genera examined, the IPC is highly ordered across most of the cell periphery but appears to be modified adjacent to the vestibulum and mid-ventral line, which represent the anamorphic zones. Variations in the size and shape of PM domains in these regions suggest that development of the IPC occurs within anamorphic zones, by the de novo formation and enlargement of inner plates throughout the cell cycle.
