Virgaviridae is a family of positive-strand RNA viruses. Plants serve as natural hosts.[1][2][3][4] The name of the family is derived from the Latin word virga (rod), as all viruses in this family are rod-shaped. There are currently 59 species in this family, divided among seven genera.[2][3][5]

| Furovirus | Rod-shaped | Helical | Non-enveloped | Linear | Segmented |
| Pecluvirus | Rod-shaped | Helical | Non-enveloped | Linear | Segmented |
| Hordeivirus | Rod-shaped | Helical | Non-enveloped | Linear | Segmented |
| Tobravirus | Rod-shaped | Helical | Non-enveloped | Linear | Segmented |
| Pomovirus | Rod-shaped | Helical | Non-enveloped | Linear | Segmented |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by leaky scanning, and suppression of termination. The virus exits the host cell by tripartite non-tubule guided viral movement, and monopartite non-tubule guided viral movement. Plants serve as the natural host.[2][3]
