Taxonomy

Virus Code. 00.015.0.02.002. (15.0.1.0.009.) Virus Accession number 15002002 (15010009).
Approved acronym: PCSV.

Virus infects plants.

Description is on taxonomic level of species. Virus is an approved species in the genus. Virus belongs to the genus "Soybean chloritic mottle-like viruses" (VC 00.015.0.02. ); family Caulimoviridae (VC 00.015. ).

Virus first reported in Arachis hypogaea. From Anantapoor, India. Reference(s): Reddy et al. (1978); Ghanekar et al. (1978).

Properties of Virion

Morphology

Virions not enveloped. Nucleocapsids isometric; 45-50 nm in diameter; appear to be round. Surface capsomer arrangement obvious.

Physicochemical an Physical Properties

Buoyant density 1.337 g cm-3 in CsCl. One sedimenting component in purified preparations. TIP: 80-85 °C. LIV: 3 days (at 4°C). DEP: log10 minus 3-4. Infectivity retained when deproteinised with phenol or detergent.

Nucleic Acid

Virions contain 16.1 % nucleic acid. Virions contain two segments of double stranded DNA.

Total genome length is 7600 nt. Sequence database accession code(s):
U13988 Gb(84)n:PCU13988 Peanut chlorotic streak virus, complete genome. 10/94 8,174bp. The largest segment 7600 nt. NCBI Taxon ID: 35593. Genomic nucleic acid isolated by Gardner and Shepherd (1980).

Proteins

Virions contain 85.9 % protein. Three structural virion proteins found. Protein size of the largest 75000 Da. Protein size of 2nd largest 44000 Da. Protein size of 3rd largest 33000 Da.

Lipids

Virions contain 0 % lipid.

Function of Helper and Satellite Viruses. Virions associated with helper virus, but independent from its functions during replication.

Cytopathology. Virions found in leaves and mesophyll; in cytoplasm. Inclusions present in infected cells. Inclusions are unusual in shape. A matrix. They contain virions.

Antigenic Properties

Serological Relationships

Virus(es) with serologically unrelated virions: cauliflower mosaic, figwort mosaic, soybean chlorotic mottle and dahlia mosaic viruses.

Biological Properties

Symptoms and Host Range

Host of virus belongs to the Domain Eucarya. Host of virus belongs to the Kingdom Plantae.

Natural Host Range and Symptoms

Symptoms persist.


Arachis hypogaea - chlorotic vein streaking and stunting. Symptoms slow to appear.

Experimental Host Range and Symptoms

Several (3-9) families susceptible.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
