Family: Marnaviridae
Genus: Salisharnavirus
Distinguishing features
Members of the genus form a separate clade from other members of the family upon phylogenetic analysis of RNA-directed RNA polymerase amino acid sequences.
Virion
See discussion under family description.
Genome organization and replication
The current members have di-cistronic genomes (Figure 2. Marnaviridae). See discussion under family description.
Biology
See discussion under family description.
Species demarcation criteria
Species demarcation cut-offs are based on pairwise comparisons of the RdRP and capsid amino acid sequences. The cut-offs are 90% identity for the RdRP and 75% identity for the capsid. The phylogenetic relationship of classified virus isolates and numerous unclassified viruses is shown in Figure 1. Salishavirus.

Figure 1. Salishavirus. Maximum likelihood tree of salisharnavirus RdRP amino sequences. The tree was produced using the JTT model with a gamma distribution of frequencies and invariant sites. Bootstrap values are shown where they were over 70%. Tips are labelled with filled circles for members of species; open circles represent unclassified viruses. Heterosigma akashiwo RNA virus (AY337486) was used as an outgroup. This phylogenetic tree and corresponding sequence alignment are available to download from the Resources page. |
