Hypoviridae is a family of viruses. Fungi serve as natural hosts. There are currently four species in this family, divided among 1 genera. Diseases associated with this family include: host virulence reduction. [1][2]

Structure

The diameter is around 50-80nm. Genomes are linear, around 9-13kb in length. The genome has 1 or 2 open reading frames.[1] Hypoviridae was the first family of viruses described that lacked a capsid.[3] and does not assemble any virion to spread.

Hypovirus No true capsid Non-Enveloped Linear Monopartite

Life Cycle

Viral replication is cytoplasmic. Replication follows the double-stranded RNA virus replication model. Double-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.[1] The virus never leaves its host and probably replicates in pleomorphic host-derived lipid vesicles. Transmission is probably dependent on host hyphal anastomosis.[3]
