Carrot red leaf
Data collated by P.M. Waterhouse, 1986.
carrot motley dwarf virus (Stubbs, 1948; 1952).
ICTV decimal code
Host range and symptoms First reported
in Daucus carota; from England; by Watson et al. (1964).
Natural host range and symptoms
Symptoms persist and vary
- Daucus carota, Anethum graveolens - chlorosis or reddening of
older leaves, but mostly symptomless.
- Anthriscus sylvestris -
reddening of leaf margins.
Transmitted by a vector; an insect;
Cavariella aegopodii; Aphididae. Transmitted in a persistent manner.
Virus retained when the vector moults; does not multiply in the vector; not
transmitted congenitally to the progeny of the vector; can help the vector
transmission of another virus (carrot mottle umbravirus); not transmitted by
mechanical inoculation; not transmitted by contact between plants; not
transmitted by seed; not transmitted by pollen.
Spreads in Australia, Canada, Germany, Japan, New Zealand,
the UK, and the USA.
Experimental host range
Few (<3) families susceptible.
Experimentally infected plants mostly show yellowing, reddening.
Diagnostically susceptible host species and symptoms
- Anthriscus cerefolium, Apium leptophyllum, Coriandrum sativum -
yellowing and reddening of older leaves.
Apium graveolens, Petroselinum crispum.
Maintenance and propagation hosts
Assay hosts (Local lesions or
Anthriscus cerefolium (W);
Apium leptophyllum (W); Coriandrum sativum (W).
Susceptible host species
Insusceptible host species
Families containing susceptible hosts
Properties of particles in sap
contains few virions.
Virions isometric; not enveloped; 25
nm in diameter; rounded in profile, or angular in profile.
One sedimenting component in purified
preparations; sedimentation coefficient 104 S. Density 1.403 g cm-3
Virions contain 28 % nucleic acid;
72 % protein; 0 % lipid.
Genome consists of RNA; single-stranded; linear. Total genome size 5.75
kb. Genome unipartite; largest (or only) genome part 5.75 kb. Genomic nucleic
acid isolated by Murant et al. (1985).
Features of proteins
Virion protein(s) four;
Mr of the largest 60000; component 1. Mr of 2nd largest
50000; minor component 2. Mr of 3rd largest 40000; minor component 3.
Mr of 4th largest 25000; coat protein (major component). Method of
preparation: Murant et al. (1985).
Replication does not depend on a helper
Virions found in phloem and companion
cells; in cytoplasm and in cell vacuoles. Inclusions present in infected cells;
are amorphous X-bodies and membranous bodies; they contain virions.
Virus(es) with serologically related virions
Barley yellow dwarf-RPV and beet western yellows viruses moderately
closely; tobacco necrotic dwarf, potato leafroll and bean leaf roll viruses
distantly; and soybean dwarf, barley yellow dwarf-MAV viruses very distantly.
Best tests for diagnosis
is the only luteovirus known to infect Apiaceae and has a very narrow host
range. It is usually found in a complex with CMotV, which unlike CRLV is sap
Carrot motley dwarf
virus (Stubbs, 1948; 1952) is a complex of carrot red leaf and carrot mottle
