Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.112.0.01.003. Virus accession number: 11201003. Obsolete virus code: 00.079.0.70.037.; 79.0.P.DE.37; superceded accession number: 79070037.; 790pde37. NCBI Taxon Identifier NCBI Taxonomy ID: 167161.

Name, Synonyms and Lineage

The taxon is listed in the current ICTV Report.

Synonym(s): strawberry mild crinkle virus. Virus is an ICTV approved species of the genus 00.112.0.01. Sadwavirus, but not assigned to a family.

Virion Properties

Morphology

Virions are not enveloped. The capsid is isometric, round and exhibits icosahedral symmetry, has a diameter of 37 nm. Capsids appear hexagonal in outline. The capsomer arrangement is not obvious.

Electron microscopic preparation and references: Reference for electron microscopic methods: Yoshikawa and Converse (1991).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.42 g cm-3. There are 1 sedimenting component(s) found in purified preparations.

Nucleic Acid

The genome is bipartite, linear, positive-sense, single-stranded RNA. Segements are distributed among 2 particle types.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Severity and Occurrence of Disease

Host: Infection is apparent, or not apparent. Signs and symptoms vary seasonally (reduced vigour and yield).

Transmission and Vector Relationships

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

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Chaetosiphon fragaraefolii, C. thomasi, C. minor, C. jacobi, Aphis gossypii. Virus is transmitted in a semi-persistent manner; lost by the vector when it moults; does not replicate in the vector; not transmitted congenitally to the progeny of the vector.

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 Amaranthaceae, Chenopodiaceae, Leguminosae-Papilionoideae, Rosaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium quinoa, Cyamopsis tetragonoloba, Fragaria chiloensis, Fragaria vesca, Fragaria virginiana, Fragaria x ananassa, Gomphrena globosa, Potentilla adscherica, Potentilla canadensis, Potentilla sterilis.

Host:
Experimentally infected hosts mainly show symptoms of Fragaria vesca shows vein clearing, mottling and dwarfing.

Diagnostic Hosts

Diagnostic host species and symptoms:

Fragaria x ananassa, Gomphrena globosa, Potentilla canadensis, P. sterilis — symptomless.

Fragaria virginiana — dwarfing of leaves.

F. vesca — mottle, vein clearing and stunting.

Potentilla adscherica — vein chlorosis.

Chenopodium quinoa — chlorotic local lesions and systemic mottling.

C. amaranticolor — vein clearing and necrotic spots.

Cyamopsis tetragonoloba — chlorotic local lesions, systemic vein clearing.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Fragaria x ananassa, F. virginiana.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Fragaria vesca (W).

References to host data: Frazier (1968, Converse (1987).

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

Cytopathology: Inclusions are not present in infected cells.

Geographical Distribution

The virus is probably distributed worldwide (where strawberries are grown).

List of Strains and Isolates in the Species

Many strains of differing severity have been described.
