Nomenclature

Acronym

ThMoV

ICTV decimal code

15.0.1.0.012

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Cirsium arvense - slight mottle.

Geographical distribution

Found, but with no evidence of spread, in the U.K.

Maintenance and propagation hosts

Cirsium arvense.

Susceptible host species

• Cirsium arvense

Families containing susceptible hosts

• Compositae (1/1)

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Donson and Hull (1983).

Particle morphology

Virions isometric; not enveloped; 50 nm in diameter; rounded in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 210 S. Density 1.36 g cm^-3 in CsCl.

Biochemical properties

Genome consists of DNA; double-stranded; circular. Total genome size 7.8 kb (pairs). Genome unipartite; largest (or only) genome part 7.8 kb (pairs). Genomic nucleic acid isolated by Donson and Hull (1983).

Features of the genome

Non-genomic nucleic acid not found in the virions.

Replication

Genome replicates presumably in nuclei and in cytoplasm (DNA to RNA in the former, RNA to DNA in the latter). Replication does not depend on a helper virus.

Cytopathology

Virions found in mesophyll; in cytoplasm. Inclusions present in infected cells; are viroplasms; they contain virions.

Taxonomy and relationships

Caulimovirus
