Narnavirus
Virus classification
Group:	Group IV ((+)ssRNA)
Family:	Narnaviridae
Genus:	Narnavirus
Type species

Species
Saccharomyces 20S RNA narnavirus Saccharomyces 23S RNA narnavirus

Narnavirus is a genus of viruses, in the family Narnaviridae. Fungi serve as natural hosts. There are currently only two species in this genus including the type species Saccharomyces 20S RNA narnavirus.^[2]^[1]

Structure

Genomes are linear and non-segmented.^[2]

Genus	Structure	Symmetry	Capsid	Genomic Arrangement	Genomic Segmentation
Narnavirus	No structural proteins		Non-Enveloped	Linear	Monopartite

Life Cycle

Viral replication is cytoplasmic. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell-to-cell movement. Fungi serve as the natural host. Transmission routes are parental and sexual.^[2]

Genus	Host Details	Tissue Tropism	Entry Details	Release Details	Replication Site	Assembly Site	Transmission
