Tymovirales
Tymovirales is an order of viruses with five families. This group consists of viruses which have sense single stranded RNA genomes without DNA intermediates. Their genetic material is protected by a special coat protein.Description
The Tymovirales are mainly plant pathogens first described in 2004. 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.Additional species
A new virus — Sclerotinia sclerotiorum deltaflexivirus 1 — has been described that appears to belong to a new genus in this family. The name Deltaflexiviridae has been proposed for this genus.
Another virus — Fusarium graminearum deltaflexivirus 1 — has been described.
