Virions are quasi-isometric or occasionally bacilliform, and are about 30 nm in diameter.
There is a short region of sequence similarity at the 3-ends of the RNAs.
The capsid protein is required for activation of replication, but may be substituted with capsid protein from the genus Alfamovirus.
Viruses in each subgroup are all serologically related, and there are also some serological cross-reactions between certain subgroups; however, there are no cross-reactions between subgroup 1 viruses and any other viruses.
The viruses infect mainly woody plants.
List of Species Demarcation Criteria in the Genus
The criteria demarcating species in the genus are:
