Ultrastructural identification of ZAM viral particles in ovarian follicles of the RevI strain from D. melanogaster. (A) A posterior follicle cell (fc) facing the oocyte (oo) from a stage 9 ovarian follicle is shown. Vm, vitelline membrane. Bar, 0.5 μm. (B) Enlargement of panel A to show the apical end of a follicle cell, where numerous roundish viral particles (arrows) (average diameter, 45 nm) can be clearly seen. Bar, 0.3 μm. (C) The apical end of a posterior follicle cell from a stage 10 ovarian follicle of the wIR6 strain showing several vitelline membrane precursors (pVm) and the vitelline membrane itself, but not viral particles. Bar, 0.9 μm. (Inset) Enlargement of the vitelline membrane precursors.
