Secoviridae
family of viruses
Secoviridae is a family of viruses in the order Picornavirales. Plants serve as natural hosts. There are 10 genera in the family, four of which are assigned to a subfamily. The family was created in 2009 with the grouping of families Sequiviridae, now dissolved, and Comoviridae, now subfamily Comovirinae, along with the then unassigned genera Cheravirus, Sadwavirus, and Torradovirus.
Taxonomy
The family includes the following genera (-virinae denotes subfamily and -virus denotes genus):
Comovirinae
Comovirus
Fabavirus
Mersevirus
Nepovirus
Unassigned to a subfamily:
Cheravirus
Sadwavirus
Sequivirus
Stralarivirus
Strawberry latent ringspot virus
Torradovirus
Waikavirus
Structure
Viruses in Secoviridae are non-enveloped, with icosahedral geometries, and T=pseudo3 symmetry. The diameter is around 25-30 nm. Genomes are linear and segmented, bipartite, around 24-7kb in length.
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model.
“Secoviridae” enters the record as family of viruses. Crown Archives preserves that source wording while asking what Secoviridae, family and viruses can confirm, complicate or overturn.
Why this record matters
“Secoviridae” is worth following because a concise public description often conceals a longer documentary argument. Here, Secoviridae, family and viruses provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 19, 2025. The linked authority identifier is Q3477217. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
