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.

Description

Tymoviruses are mainly plant pathogens first described in 2004.[1] They are characterised by similarities in their replication-associated polyproteins. These account for the majority of their genomic coding capacity. They are considered to form a group, phylogenetically, referred to as flexiviruses, with filamentous virions.[2]

Additional species

A new virus — Sclerotinia sclerotiorum deltaflexivirus 1 — has been described that appears to belong to a new genus in this family.[3] The name Deltaflexiviridae has been proposed for this genus.

Another virus — Fusarium graminearum deltaflexivirus 1 — has been described.[4]

gollark: Oh. Hmm. Why?

gollark: I could do that, but it would be hard to make it know which webpages.

gollark: That could be implemented without browser support actually. Hmm.
