Nomenclature

Synonyms

loganberry calico virus.

Acronym

WLV

ICTV decimal code

56.0.1.T.020

Host range and symptoms

Natural host range and symptoms

Symptoms vary seasonally. Symptoms chlorotic or yellow line pattern.
• Rubus phoenicolasius - symptomless. However, it has been shown to induce calico disease-like symptoms in blackberry.

Transmission

Not transmitted by Macrosiphum euphorbiae. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Spreads in the USA. Found, but with no evidence of spread, in the U.K.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show necrotic or red local lesions.

Diagnostically susceptible host species and symptoms

• Gomphrena globosa, Chenopodium album, C. amaranticolor, C. ambrosioides, C. murale, C. quinoa - necrotic local lesions.

Diagnostically insusceptible host species

Nicotiana clevelandii, N. debneyi, N. glutinosa, N. tabacum, Phaseolus vulgaris.

Maintenance and propagation hosts

Chenopodium amaranticolor, C. quinoa, Gomphrena globosa.

Physical and biochemical properties

Properties of particles in sap

TIP: less than 70 °C. LIV: less than 8 days (at 18ºC). DEP: log₁₀ minus 3-4. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains few virions.

Purification method

Jones et al. (1990).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 620 nm; 12 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

Sometimes two sedimenting components in purified preparations; sedimentation coefficient 115-125 S. Density 1.29 and 1.3 g cm^-3 in CsCl. Density 1.25 and 1.26 g/cm³ in Cs₂SO₄. A₂₆₀/A₂₈₀ ratio 1.26.

Biochemical properties

Virions contain 5 % nucleic acid; 95 % protein.

Genome consists of RNA; single-stranded; linear. Total genome size 8.5 kb. Genome unipartite. Genomic nucleic acid isolated by Jones: use proteinase K + phenol.

Features of the genome

Non-genomic nucleic acid not found in the virions. 1 virus specified dsRNA species found in infected cells. Size of largest virus specified dsRNA 17 kbp.

Features of proteins

Virion protein(s) one; M_r 31000. Method of preparation: Jones et al. (1990).

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves and all parts of the host plant.

Taxonomy and relationships

(ungrouped)

Virus(es) with serologically unrelated virions

9 carlaviruses.

Best tests for diagnosis

ISEM and mechanical inoculation to Chenopodium quinoa.
