Classification

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

ICTVdB Virus Code: 00.000.4.00.001. Virus accession number: 00400001. Obsolete virus code: 00.079.0.70.006.; 79.0.P.DE.06; superceded accession number: 79070006; 790pde06.

Name, Synonyms and Lineage

Synonym(s): black raspberry mild mosaic virus, raspberry black necrosis virus. ICTV approved acronym: BRNV. Virus is unclassified and not assigned to a genus or family..

Virion Properties

Morphology

Virions are not enveloped. The capsid is round and exhibits icosahedral symmetry. The isometric capsid has a diameter of 25-30 nm. Capsids appear round. The capsomer arrangement is not obvious.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Murant et al. (1976).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 1-2.

Nucleic Acid

The genome is monopartite, only one particle size is recovered.

Proteins

The viral genome encodes structural proteins.

Lipids

Lipids are not reported.

Diagnostics and Reference Collections

The best tests for diagnosis are aphid transmission to Rubus indicator hosts.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

General Symptoms in Plants Symptoms mild leaf mottle.

Severity and Occurrence of Disease

Host: Infection is apparent, or not apparent. Signs and symptoms disappear soon after infection.

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; not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Amphorophora agathonica, A idaei, A rubicumberlandii, Illinoia rubicola. 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 few families. Susceptible host species are found in the Family Amaranthaceae, Chenopodiaceae, Rosaceae, Solanaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Gomphrena globosa, Nicotiana debneyi, Petunia x hybrida, Rubus fruticosus, Rubus henryi, Rubus idaeus, Rubus lasiocarpus, Rubus loganobaccus, Rubus occidentalis, Rubus phoenicolasius, Rubus procerus, Rubus ursinus, Spinacia oleracea.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor, C. quinoa, Gomphrena globosa, Nicotiana debneyi, Petunia x hybrida, Spinacia oleracea — local chlorotic lesions.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Rubus idaeus, R. occidentalis.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Rubus occidentalis (W), R. henryi (W).

References to host data: Jones and Murant (1972, Murant et al. (1976).

Histopathology: Virus can be best detected in the leaves.

Geographical Distribution

The virus occurs in Australia, Canada, France, Germany, Italy, the Netherlands, New Zealand (Aotearoa), Norway, Poland, and the United States of America. The virus is found, but with no evidence of proliferation, in Australia and New Zealand.

Ecology, Epidemiology and Control

Studies reported by Jones and Jennings (1986).
