Figure 1 Negative contrast electron micrographs of virions of an isolate of Acidianus bottle-shaped virus. (Top) Intact virions. (Bottom, left) Horizontal slice (0.7 nm) though the three dimensional data set of the 3D reconstruction of the virion. (Bottom, center) partially disrupted virions. (Bottom, right) Schematic representation of the virion. The scale bars represent 100 nm.

Figure 2 Genome organisation of Acidianus bottle-shaped virus, showing location, sizes and direction of putative genes. The square indicates the position of the RNA gene. Red arrows indicate genes with assigned functions or recognizable structural motifs, while putative genes of unknown structure and function are denoted by yellow arrows. Three internal ORFs are denoted by green arrows and their amino acid sizes are given in brackets.
