Isolate Description

Location: Devon, England; the United Kingdom.

Host of Isolate and Habitat Details
Source of isolate: Avena sativa.

Natural host and symptoms
Avena sativa — yellow striping on two youngest leaves.

Many plants may have infected roots, but show no systemic symptoms.

Reference to Isolation Report
Plumb et al. (1977).

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: 00.027.0.01.002. Virus accession number: 27001002. Obsolete virus code: 27.0.1.0.002; superceded accession number: 27010002.
NCBI Taxon Identifier NCBI Taxonomy ID: 45103.

Name, Synonyms and Lineage

Synonym(s): oat chlorotic stripe virus, oat tubular virus (Plumb and MacFarlane, 1978), soil-borne oat stripe virus. ICTV approved acronym: OGSV. Virus is an ICTV approved species of the genus 00.027.0.01. Furovirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. Virus preparations contain more than one particle component. The capsid is rod-shaped, straight with a clear modal length; with a length of 150-300 nm and a width of 20 nm. Axial canal is distinct. Basic helix is obscure.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Adams et al. (1988).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.321 g cm-3. There are 2 sedimenting component(s) found in purified preparations. The sedimentation coefficient is of the fastest 218 S20w; of the other(s) are 168 S20w.

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. The complete genome is 9700 nucleotides long. Genome is sequenced, complete sequence is about 6200 nucleotides long, is sequenced, but only an estimate is available, complete sequence is 3500 nucleotides long. The multipartite genome is divided among more than one type of particle. Reference to nucleotide sequence isolation method by Jones: proteinase K incubation followed by phenol/chloroform and precipitation with ethanol.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s).

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to soil borne wheat mosaic virus. The virus does not show serological relationships to Beet necrotic yellow vein, Hypochoeris mosaic and potato mop top viruses.

Very distantly serologically related to potato M and red clover vein mosaic carlaviruses.

Diagnostics and Reference Collections

The best tests for diagnosis are often found with oat mosaic virus. Distinguish by virion morphology in EM 'dip preparations'.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

Class Liliopsida (Monocotyledonae)
Subclass COMMELINIDAE; Order Poales;
Family Poaceae. Virus found in Avena sativa.

General Symptoms in Plants Symptoms yellow striping on tip leaves when systemically infected.

Severity and Occurrence of Disease

Host: Signs and symptoms vary seasonally.

Transmission and Vector Relationships

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

Vector Transmission:
Virus is transmitted by fungi (presumably, of the order Plasmodiophorales; Polymyxa graminis. The principal natural vector(s) are Polymyxa graminis.

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, Gramineae, Solanaceae. The following species were susceptible to experimental virus infection: Avena sativa, Chenopodium amaranticolor, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana debneyi.

Host:
Experimentally infected hosts mainly show symptoms of mottling; striping rare in glasshouse plants.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Gramineae, Leguminosae-Papilionoideae. Species inoculated with virus that do not show signs of susceptibility: Hordeum vulgare, Phaseolus vulgaris, Triticum aestivum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Avena sativa — yellow mottling and stripes on leaves; systemic infection.

Nicotiana clevelandii, Chenopodium amaranticolor — necrotic local lesions, sometimes systemic in N. clevelandii.

Nicotiana debneyi — chlorotic local lesions.

Nicotiana benthamiana. Diagnostic host: insusceptible host species Triticum sp., Hordeum vulgare, Phaseolus vulgaris.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Avena sp.

References to host data: Plumb et al. (1977).

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

Cytopathology: Other cellular changes include disruption of organelles (Plumb et al., 1977).

Geographical Distribution

The virus occurs in France, the United Kingdom, and the United States of America (North Carolina).
