Carnation vein
mottle potyvirus
Index
Data collated by J.R. Moran, M. Verhoyen and G. van
Caneghem, 1987.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Dianthus caryophyllus; from the U.S.A.; by Kassanis (1954).
Natural host range and symptoms
- Dianthus
caryophyllus - chlorotic and darker green spots, flecks and mottling.
Flower breaking and malformation.
- Dianthus barbatus - mottle.
Transmission
Transmitted by a vector; an insect;
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
Hollings et al. (1977); Poupet et al. (1981). Stocks freed from
virus by tip propagation and heat treatment.
Geographical
distribution
Probably distributed worldwide (wherever carnations are
grown).
Experimental host range
Few (<3) families susceptible.
Experimentally infected plants mostly show chlorotic and necrotic local lesions
rarely systemic.
Diagnostically susceptible host species and
symptoms
- Chenopodium amaranticolor - chlorotic and
necrotic local lesions; not systemic.
- Chenopodium quinoa -
chlorotic spots, local lesions; systemic spotting.
- Silene pendula
- necrotic local lesions, systemic chlorotic or necrotic spots (Tochihara
et al., 1975).
Maintenance and propagation hosts
Chenopodium quinoa, Dianthus barbatus.
Assay hosts (Local lesions or Whole plants)
Chenopodium quinoa (L), Chenopodium amaranticolor (L).
Susceptible host species
Insusceptible host species
Families containing susceptible hosts
Families containing
insusceptible hosts
Sources of host-range data
Hollings
and Stone (1977); Tochihara et al. (1975).
Physical and
biochemical properties
Properties of particles in sap
TIP:
55-65 °C. LIV: 2-10 days. DEP: log10 minus 2-5. Leaf sap contains many
virions.
Purification method
Hollings and
Stone (1971); Borges et al. (1981).
Particle morphology
Virions filamentous; not enveloped;
usually flexuous; of 790 nm; 12 nm wide. Axial canal obvious.
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 144 S.
Biochemical properties
Genome consists of RNA;
single-stranded. Base composition 21 % G; 25 % A; 28 % C; 29 % U.
Features of proteins
Virion protein(s) one;
Mr 32000-34800.
Cytopathology
Virions found in all parts of the host
plant; in unusual sites; in a single, thin layer between two membranes just
inside the tonoplast. Inclusions present in infected cells; are pinwheels and
unusual in shape; dense bands, loops and circles (Weintraub, 1970) or tubular
structures (Bergtrup, 1976); they do not contain virions. Other cellular
changes: elongated nuclei with abnormally electron dense areas of chromatin.
Taxonomy and
relationships
Virus(es) with serologically related virions
Bean yellow mosaic, pepper veinal mottle, pea mosaic, freesia streak,
turnip mosaic (cabbage black ring strain) and watermelon mosaic 2 viruses
(Borges, 1981).
Virus(es) with serologically unrelated
virions
Turnip mosaic (tigridia mosaic strain),
narcissus degeneration, clover yellow vein, narcissus yellow stripe, hippeastrum
mosaic, potato veinal necrosis, iris mosaic, potato Y, sugar beet mosaic,
tobacco severe etch and lettuce mosaic viruses.
Best tests for diagnosis
For
electron microscopy use leaf sap, virus aggregates are found in plant membranes.
CVMV can be distinguished from carnation latent virus either by ISEM decoration
or by inoculation to Chenopodium amaranticolor, which carnation latent
infects systemically, but CVMV does not.
