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]

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]
