00.082. Ascoviridae

Figure 1: Morphology of ascovirus virions. (Top left) Schematic illustration of the structure of a typical ascovirus virion. The virion consists of an inner particle and an outer envelope. The inner particle is complex and contains a DNA/protein core surrounded by an apparent unit membrane, the external surface of which bears a layer of distinctive protein subunits. (Center left, Bottom left) Respectively, ultrathin longitudinal- and cross-sections through typical ascovirus virions. The dense inner layer corresponds with the distinctive layer of subunits shown in Top left. (Right) Negatively stained reparations of virions from three different ascovirus species: Top right, Spodoptera frugiperda ascovirus 1a preparations Center right, Trichoplusia ni ascovirus 2a (TnAV-2a), and Bottom right, Heliothis virescens ascovirus 3a (HvAV-3a). The reticulate appearance of the virions is thought to be due to the superimposition of top and bottom layers of the inner particle and outer envelope.
