FIGURE 3.

Electron tomography of P. massiliensis particle from Movie 4. (A) Single plane in the tomogram from Movie 4 showing a whole Pandoravirus particle and its ostiole located at one apex (arrow). (B). The inner-most layer is composed of two thick tubules well separated (black arrowheads) or contacting each other (white arrowheads). (C,D) Thin fibers (arrows) originating from the inner-most tubular thick layer projecting toward the peripheral sugars (white arrows, C), toward the inner core of the particle (white arrow, D) or at the level of the ostiole (black arrow, D).
