Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Pastinaca sativa; from the U.K. in Scotland; by Murant and Munthe
(1967).
Natural host range and symptoms
Symptoms disappear soon
after infection.
- Pastinaca sativa - mild mosaic.
Transmission
Transmitted by a vector; an insect;
Carvariella aegopodii, C. theobaldi, Myzus persicae; Aphididae.
Transmitted in a non-persistent manner. Virus transmitted by mechanical
inoculation.
Geographical distribution
Experimental host range
Several (3-9) families
susceptible. Experimentally infected plants mostly show veinal necrosis and
local lesions.
Diagnostically susceptible host species and
symptoms
- Anthriscus cerefolium, Bupleurum rotundifolium,
Coriandrum sativum, Daucus carota, Thaspium aureum, Trachymene pilosa -
systemic veinal necrosis.
- Chenopodium amaranticolor, C. quinoa, Gomphrena
globosa, Spinacia oleracea - local lesions; no systemic infection.
Diagnostically insusceptible host species
Beta vulgaris,
Brassica campestris ssp. pekinensis, Cucumis melo, Datura stramonium,
Nicotiana clevelandii.
Maintenance and propagation hosts
Chenopodium quinoa, Coriandrum sativum.
Assay hosts
(Local lesions or Whole plants)
Chenopodium amaranticolor (L), C. quinoa (L).

Physical and
biochemical properties
Properties of particles in sap
TIP:
55-58 °C. LIV: 7-10 days (at 18ºC). DEP: log10 minus 3-4.
Particle morphology
Virions filamentous; usually
flexuous; with a clear modal length; of 736 nm; 14 nm wide.
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 149 S.
Cytopathology
Virions found in leaves and mesophyll; in
cytoplasm. Inclusions present in infected cells; are pinwheels.
Taxonomy and
relationships
Virus(es) with serologically unrelated virions
Bean yellow mosaic, clover yellow vein, cocksfoot streak, henbane
mosaic, iris mild mosaic, lettuce mosaic, pea mosaic, turnip mosaic, tulip
breaking, potato Y and celery mosaic viruses.
