Megabirnaviridae
provided by wikipedia EN

Megabirnaviridae is a family of viruses. Fungi serve as natural hosts. There is only one species in this family: the type species Rosellinia necatrix megabirnavirus 1. Diseases associated with this family include: reduced host virulence.[1][2]

Taxonomy

Group: dsRNA

Order: Unassigned
  • Family: Megabirnaviridae

Structure

Viruses in Megabirnaviridae are non-enveloped, with icosahedral geometries, and T=1 symmetry. The diameter is around 50 nm. Genomes are linear and segmented, around 7kb in length. The genome codes for 4 proteins.[1]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. 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. Transmission routes are parental and sexual.[1]
