The photoreceptor of newly emerged flies was characterized by the rich content of rough-surfaced endoplasmic reticulum (rER) and the small rhabdomere : the photoreceptor is actively constructing rhabdomere, and therefore suitable to study the mechanism of rhabdomere morphogenesis. The photoreceptor specifically contained opsin-bearing structures some of which were enclosed by several layers of membranes. The structure became sparse in 10 d old flies. Opsins in the structure may be incorporated into the new rhabdomere. The antiopsin also labeled the plasma membrane facing to the intraommatidial space and the endomembranes in the cell body. Both regions were furnished by uniformly oriented actin filaments with the plus ends towards the rhabdomere. Such orientation makes the actin filaments possible to be involved in the vectorial transport of materials towards the rhabdomere by a presumptive interaction with the myosin-like ninaC proteins identified in Drosophila photoreceptors.}, pages = {391--398}, title = {Immunogold colocalization of opsin and actin in Drosophila photoreceptors that undergo active rhabdomere morphogenesis}, volume = {11}, year = {1994} }
