Index
Data collated by W.E. Howell and A.A. Brunt, 1991.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Daucus carota; from Washington State, U.S.A.; by Howell and Mink
(1976).
Natural host range and symptoms
Symptoms persist.
Symptoms malformation, leaf narrowing and some vein clearing.
- Daucus carota, Conium maculatum - symptomless.
- Daucus
carota ssp. sativus - leaflet lobes malformed and narrow, vein
clearing and some chlorotic spots.
Transmission
Transmitted by a vector; an insect;
Cavariella aegopodii, Myzus persicae; Aphididae. Transmitted in a
non-persistent manner. Virus transmitted by mechanical inoculation; not
transmitted by contact between plants; not transmitted by seed.
Ecology and control
Studies reported by Howell and Mink
(1977a and b).
Geographical distribution
Experimental host range
Several (3-9) families
susceptible. Experimentally infected plants mostly show systemic thread like
leaflets, twisted leaves, vein clearing in Apiaceae; chlorotic and necrotic
local lesions in Chenopodium.
Diagnostically
susceptible host species and symptoms
- Anthriscus
cerefolium - thread like leaflets.
- Apium australe -
chlorosis and death of older leaves.
- Chenopodium quinoa -
chlorotic and necrotic local lesions.
- C. amaranticolor - chlorotic
and red ring local lesions.
- Coriandrum sativum, Daucus carota ssp.
sativus - thread like leaflets, vein clearing.
- Pastinaca
sativa, Petroselinum crispum, Zinnia elegans - symptomless.
Diagnostically insusceptible host species
Apium
graveolens var. dulce, Cucumis sativus, Datura stramonium, Nicotiana
tabacum, Phaseolus vulgaris.
Maintenance and propagation hosts
Chenopodium quinoa, Coriandrum sativum, Daucus carota.
Assay hosts (Local lesions or Whole plants)
Chenopodium amaranticolor (L),
C. quinoa (L), Coriandrum sativum (W), Daucus carota (W).

Physical and
biochemical properties
Properties of particles in sap
TIP:
50-55 °C. LIV: 2 days. DEP: log10 minus 5-6. Leaf sap contains few virions.
Purification method
Particle morphology
Virions filamentous; not enveloped;
usually flexuous; with a clear modal length; of 736 nm; 11 nm wide. Axial canal
obscure.
Physical properties
One sedimenting component in purified
preparations, or two sedimenting components in purified preparations.
A260/A280 ratio 1.18.
Biochemical properties
Replication
Replication does not depend on a helper
virus.
Cytopathology
Virions found in leaves, stems and roots.
Inclusions present in infected cells; are pinwheels.
Taxonomy and
relationships
Virus(es) with serologically unrelated virions
Bean common mosaic, bean yellow mosaic, celery mosaic, clover yellow
vein, iris mild mosaic, parsnip mosaic, pea seed-borne mosaic, peanut mottle,
potato Y, soybean mosaic, sugarcane mosaic, tobacco etch and turnip mosaic
viruses.
