Isolate Description

Location: New Jersey; the United States of America.

Host of Isolate and Habitat Details
Source of isolate: Vaccinium ssp.

Natural host and symptoms
Vaccinium corymbosum, V. angustifolium — "shoestring" disease; reddish streaks on stems, narrow strap-like leaves, occasional flower-breaking, severe yield reduction.

Reference to Isolation Report
Varney (1957).

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: 00.067.0.01.002. Virus accession number: 67001002. Obsolete virus code: 67.0.1.0.002; superceded accession number: 67010002.

Name, Synonyms and Lineage

ICTV approved acronym: BSSV. Virus is an ICTV approved species of the genus 00.067.0.01. Sobemovirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 27 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: Ramsdell (1979a, Ramsdell (1979b).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.392 g cm-3. The density of virions is 1.273 in Cs2SO4 and 1.355 g/cm3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 120 S20w. Isoelectric point pH is 4.6-4.7.

Nucleic Acid

The Mr of the genome constitutes 20% of the virion by weight (in the single component). The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered. Minor species of non-genomic nucleic acid are not found in virions. The complete genome is 4200 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 4200 nucleotides long. Reference to nucleotide sequence Ramsdell (1979b).

Proteins

Proteins constitute about 80% of the particle weight (in the single component).

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

Structural Proteins: Reference to method of preparation: Ramsdell (1979b).

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Transcription: Sub-genomic RNA is absent from infected cells.

Translation: Virions may provide helper functions to dependent virus during replication.

Antigenicity

The virus does not show serological relationships to 33 viruses with isometric virions (Ramsdell, 1979a).

Diagnostics and Reference Collections

The best tests for diagnosis are look for reddish streaks on stems.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Class Magnoliopsida (Dicotyledonae)
Subclass DILLENIIDAE.

Severity and Occurrence of Disease

Host: Signs and symptoms persist and vary seasonally.

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; Masonaphis pepperi. Virus is transmitted in a semi-persistent manner (probably, 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 Ericaceae. The following species were susceptible to experimental virus infection: Vaccinium, Vaccinium angustifolium, Vaccinium corymbosum.

Host:
Experimentally infected hosts mainly show symptoms of malformation, streaking.

Diagnostic Hosts

Diagnostic host species and symptoms:

Vaccinium ssp. — oak leaf pattern on leaves malformed shoestring leaves, red streaks on stems; blossoms pink.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Vaccinium corymbosum.

References to host data: Ramsdell (1979a).

Histopathology: Virus can be best detected in mesophyll, epidermis, meristem, xylem, phloem and palisade parenchyma. Virions are found in the cytoplasm, nucleus, and cell vacuole (in small cytoplasmic vacuoles).

Cytopathology: Inclusions are not present in infected cells. Other cellular changes include rod-like materials in palisade cells (Hartman et al., 1973).

Geographical Distribution

The virus occurs in the United States of America (in Michigan and New Jersey).

Ecology, Epidemiology and Control

Studies reported by Morimoto and Ramsdell (1985, Morimoto et al. (1985).
