Tentative Species in the Genus
List of Unassigned Viruses in the Family
The species that follow could not be allocated to any of the genera either because the available information is scanty
(Megakepasma mosaic virus; MegMV and Alligatorweed stunting virus; AWSV), or because more molecular
(Olive leaf yellowing-associated virus; OLYaV and Grapevine leafroll-associated virus 7; GLRaV-7) or
biological data (Little cherry virus 1; LChV-1) are needed for unequivocal classification.

Similarity with other Taxa
Virions of the genera Capillovirus, Trichovirus, and Vitivirus have the same particle morphology as those
of the family Closteroviridae. However, the sequence of the CP of members of this family has little homology with that of CPs
of viruses in the three above genera, and major differences exist in genome size and organization, and strategy of expression.
Replication-associated proteins (RdRp, Mtr and Hel) contain signature sequences homologous to those of other taxa of the "alpha-like"
supergroup of ssRNA viruses, the closest affinity being with the family Bromoviridae and the genera Tobravirus,
Tobamovirus, and Hordeivirus. The replication strategy, based on polyprotein processing, translational frameshifting,
and multiple sgRNA generation, closely resembles that of viruses in the families Coronaviridae and Arteriviridae.
However, unlike closteroviruses, the RdRp of coronaviruses and arteriviruses belong to the "picorna-like" supergroup of polymerases.
Hence, the transcriptional strategy of members of the family Closteroviridae follows the mechanism of other "alpha-like" viruses,
and is dissimilar from the discontinuous, leader-primed transcription of coronaviruses and arteriviruses.
Derivation of Names
ampelo: from ampelos, Greek for grapevine, the host of the type species of the genus;
clostero: from Greek kloster, 'spindle, thread';
crini: from crinis, Latin for hair, from the appearance of the very long thread-like particles.
