Figure 1 (Left) Schematic presentation of cystovirus particle (Pseudomonas phage phi6) with location of virion proteins. (Middle) Three-dimensional reconstructions of the nucleocapsid. (Right) Thin-section electron micrograph of Pseudomonas phage phi6 particles attached to the pilus receptor. The bar represents 200 nm.
Figure 2 Genome organization of Pseudomonas phage phi6. The gene and protein numbers are the same. Genes encoding constituents of the polymerase complex and nucleocapsid are in green and blue, respectively. Genes encoding envelope associated proteins are in purple, and non-structural proteins in orange.

(G) Polymerase complex assembly. (H) ssRNA packaging and replication. (I) Late transcription. (J) Nucleocapsid shell assembly. (K) Translocation of the viral envelope and assembly of spikes. (L) Host cell lysis and release of mature virions.
