FIG. 1.

Maturation of RRV particles. (A) TEM of intranuclear RRV capsids 6 days postinfection. Three morphologically distinct capsid species are evident. The inset displays the dashed boxed area at a greater magnification with type A, B, and C capsids indicated. (B) Released RRV particles collected from the supernatant of infected RhF. Virions contain a capsid with an inner density surrounded by a tegument layer (t) and an envelope layer with protrusions consistent with glycoproteins (g). A capsid (c) lacking these two outer layers is also present in this micrograph.
