Tymovirales
''Tymovirales'' is an order of viruses with five families. The group consists of viruses which have positive-sense, single-stranded RNA genomes. Their genetic material is protected by a special coat protein.

Tymoviridae
''Tymoviridae'' is a family of single-stranded positive sense RNA viruses in the order ''Tymovirales''. Plants serve as natural hosts. There are 42 species in this family, assigned to three genera, with two species unassigned to a genus.

''. Plants serve as natural hosts. There is only one species in this genus: ''Grapevine fleck virus''.
Structure
Viruses in ''Maculavirus'' are non-enveloped, with icosahedral and isometric geometries. The diameter is around 30 nm. Genomes are linear, around 7.5kb in length.
Life cycle
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. The virus exits the host cell by monopartite non-tubule guided viral movement.
Plants serve as the natural host. The virus is transmitted via a vector (unknown). Transmission routes are vector and mechanical.
