Index
Data collated by J. Cooper, 1986.
Nomenclature
Synonyms
aesculus line pattern virus (Schmelzer and
Schmidt, 1968), rhubarb virus 5.
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Fragaria vesca and Rubus idaeus; from Dundee, Scotland; by
Lister (1964).
Natural host range and symptoms
- Fragaria vesca
(strawberry) - mottle and death.
- Apium graveolens - strap leaf.
- Robinia pseudoacacia - mosaic.
- Rosa spp. - chlorotic
ringspots and stunting.
- Euonymus europaeus - yellow mottle.
- Aesculus carnea - line pattern.
- Rubus idaeus -
stunting. Other natural hosts include:
- Rubus fruticosus.
- Ribes
nigrum.
- Ribes rubrum.
- Asparagus officinalis.
- Vitis vinifera.
- Capsella bursa-pastoris, Delphinium spp.,
Lamium amplexicaule, Narcissus spp., Prunus domestica, P. persica,
Rheum rhaponticum, Sambucus nigra, Senecio vulgaris, Stellaria media, Taraxacum
officinale, Trifolium repens and Urtica dioica.
Transmission
Transmitted by a vector; a nematode;
Xiphinema diversicaudatum; Dorylamidae. Virus transmitted by mechanical
inoculation; transmitted by grafting; transmitted by seed (often more than 70%
in Capsella bursa-pastoris, Mentha arvensis, Lamium amplexicaule, Rubus
idaeus, Senecio vulgaris, Stellaria media, Chenopodium quinoa, Pastinaca sativa,
Petroselinum crispum and Apium graveolens).
Geographical
distribution
Spreads in Australia, Belgium, Canada, Finland, France,
Germany, Ireland, Israel, Italy, Luxembourg, the Netherlands, New Zealand,
Poland, Portugal, Romania, Spain, Switzerland, Turkey, the UK, the USA, the
former Yugoslavia. Found, but with no evidence of spread, in Canada and New
Zealand.
Experimental host range
Many (>9) families
susceptible.
Diagnostically susceptible host species and
symptoms
- Chenopodium amaranticolor, C. murale, C. quinoa
- chlorotic or necrotic local lesions, systemic chlorosis and deformation,
necrosis or faint chlorotic mottle.
- Cucumis sativus - chlorotic
local lesions or none; systemic interveinal chlorosis or necrosis; recovery in
summer, in winter symptoms may persist. Some isolates induce enations.
Diagnostically insusceptible host species
Nicotiana
rustica, Nicotiana tabacum, Petunia × hybrida.
Maintenance and
propagation hosts
Assay hosts
(Local lesions or Whole plants)
Chenopodium murale (L), Chenopodium amaranticolor (L).

3-5. Infectivity of sap not changed by treatment with di-ethyl ether.
Purification method
Lister (1964);
Richard and Proll (1970); Allen et al. (1970).
Particle morphology
Virions isometric; 30 nm in diameter;
angular in profile.

purified preparations; sedimentation coefficient of the fastest 126-134 S
(B); of the other(s) 50-58 S (T). Density 1.46 g cm-3 in CsCl (B).
Biochemical properties
Virions contain 38 % nucleic acid
(B); 62 % protein (T).
Genome consists of RNA; single-stranded. Total genome size 12.6 kb.
Genome of two parts (Mayo et al., 1974); largest (or only) genome part
7.8 kb; the 2nd largest 4.8 kb. Genomic nucleic acid isolated by Mayo et
al. (1974).

Cytopathology
Virions found in mesophyll and epidermis;
in the perinuclear space. Inclusions present in infected cells; are membranous
bodies and unusual in shape; and tubules; they contain virions (and empty
shells).
