Tymovirales is an order ofviruses with five families. The group consists of viruses which havepositive-sense, single-stranded RNA genomes. Their genetic material is protected by a specialcoat protein.
Tymoviruses are mainly plant pathogens first described in 2004.[1] They are characterised by similarities in theirreplication-associatedpolyproteins. These account for the majority of theirgenomiccoding capacity. They are considered to form a group,phylogenetically, referred to as flexiviruses, with filamentousvirions.[2]
