Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.015.0.02.002. Virus accession number: 15002003. Obsolete virus code: 15.0.1.0.009; superceded accession number: 15010009.
NCBI Taxon Identifier NCBI Taxonomy ID: 35593.

Name, Synonyms and Lineage

ICTV approved acronym: PCSV. Virus is an ICTV approved species of the genus 00.015.0.02. Soymovirus in the family 00.015. Caulimoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The capsid is isometric has a diameter of 45-50 nm. Capsids appear round. The capsomer arrangement is clearly visible.

Electron microscopic preparation and references: Virus preparation contains few virions.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.337 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The thermal inactivation point (TIP) is at 80-85°C. The longevity in vitro (LIV) is 3 days (at 4°C). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3-4. The infectivity is retained when deproteinized with phenol or detergent.

Nucleic Acid

The Mr of the genome constitutes 16.1% of the virion by weight. The genome is segmented and consists of two segments of circular. The genome is -RT. The genome is double-stranded DNA. The genome is fully sequenced and complete sequence is 8174 nucleotides long. Sequence has the accession number [U13988]. Reference to nucleotide sequence Gardner and Shepherd (1980).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 85.9% of the particle weight.

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 3 structural protein(s).

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are not reported.

Transcription: The virus codes for 8 ORF(s).

Translation: Replication involves a reverse transcription step.

Antigenicity

The virus does not show serological relationships to cauliflower mosaic, figwort mosaic, soybean chlorotic mottle and dahlia mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation; transmitted by grafting; transmitted by contact between hosts; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Aphis craccivora.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in several families. Susceptible host species are found in the Family Chenopodiaceae, Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Arachis hypogaea, Canavalia ensiformis, Cyamopsis tetragonoloba, Datura stramonium, Glycine max, Nicandra physalodes, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum, Nicotiana x edwardsonii, Petunia x hybrida, Phaseolus vulgaris, Spinacia oleracea, Vicia faba, Vigna radiata, Vigna unguiculata.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, Cruciferae, Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae. Species inoculated with virus that do not show signs of susceptibility: Brassica campestris, Brassica juncea, Brassica oleracea var. botrytis, Cajanus cajan, Cassia obtusifolia, Chenopodium amaranticolor, Chenopodium quinoa, Gomphrena globosa, Phaseolus vulgaris (cv. Kintoki), Pisum sativum, Raphanus sativus, Trifolium incarnatum, Vicia faba.

Diagnostic Hosts

Diagnostic host species and symptoms:

Canavalia ensiformis — local and systemic chlorotic spotting.

Cyamopsis tetragonoloba — necrotic local lesions; systemic vein-clearing.

Glycine max — systemic mosaic.

Phaseolus vulgaris cv. Top Crop — local lesions, systemic mosaic.

Vicia faba — chlorotic or necrotic local lesions; not systemic.

Datura stramonium, Nicotiana rustica — chlorotic local lesions; systemic mosaic.

Nicotiana glutinosa — systemic chlorotic spots.

Petunia x hybrida — systemic mosaic.

Vigna unguiculata — chlorotic local lesions with necrotic centre; not systemic.

Diagnostic host: insusceptible host species Chenopodium amaranticolor, C. quinoa, Brassica oleracea var. botrytis, Cassia obtusifolia, Cajanus cajan, Trifolium incarnatum, Raphanus sativus, Gomphrena globosa, Pisum sativum, Phaseolus vulgaris cv. Kintoki.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana benthamiana, N. x edwardsonii, N. glutinosa, N. rustica, N. clevelandii, Petunia x hybrida.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Datura stramonium (L,W), Spinacia oleracea (L), Vigna unguiculata (L), Phaseolus vulgaris cv. Top Crop (L,W).

Histopathology: Virus can be best detected in leaves and mesophyll. Virions are found in the cytoplasm.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Inclusions are a matrix. Inclusions contain mature virions.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Caulimoviridae at the meeting in Strasburg, April 1997. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997, the taxon has been removed from the Species (Caulimovirus).
