Table 1. Characteristics of the family Cystoviridae.

Typical member: Pseudomonas phage phi6 (Segment S, M12921; Segment M, M17462; Segment L, M17461), species Pseudomonas virus phi6, genus Cystovirus
Virion Enveloped virions (~85 nm) with two concentric, icosahedrally symmetric protein layers: the nucleocapsid surface shell (T=13) and the polymerase complex core (T=1). Spikes protrude from the virion surface
Genome Three segments of linear, double-stranded RNA, totaling 13.4 kbp, encoding 13 genes
Replication Single-stranded genomic precursor molecules are packaged into the viral polymerase complex. The packaged RNA molecules are replicated and transcribed within the particle
Translation Viral proteins are translated from polycistronic messenger RNA molecules
Host range Gram-negative bacteria, mostly Pseudomonas species
Taxonomy One genus (Cystovirus) and one species (Pseudomonas virus phi6)
