Nomenclature

Acronym

CoLV

ICTV decimal code

14.0.T.1.011

Host range and symptoms

Natural host range and symptoms

Symptoms none.
• Brassica oleracea - usually symptomless.

Transmission

Transmitted by a vector; an insect; Myzus persicae, but transmits infrequently; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by seed.

Geographical distribution

Spreads in Brazil (in the states of San Paulo and the Federal District).

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show latent infection, some show local lesions.

Diagnostically susceptible host species and symptoms

• Gomphrena globosa, Chenopodium amaranticolor, C. quinoa, Malva parviflora - local lesions.
• Brassica oleracea var. acephala, B. oleracea var. botrytis, Raphanus sativus, Citrullus lanatus, Glycine max, Solanum melongena - latent.

Diagnostically insusceptible host species

Dianthus caryophyllus, Lactuca sativa, Zea mays, Phaseolus vulgaris, Capsicum annuum.

Maintenance and propagation hosts

Physical and biochemical properties

Properties of particles in sap

TIP: 75-80 °C. LIV: 2-4 days. DEP: log₁₀ minus 3-4. Leaf sap contains few virions.

Purification method

Extraction, clarification, precipitation with PEG 6000, differential centrifugation (2 cycles).

Particle morphology

Virions filamentous; not enveloped; usually straight; with a clear modal length; of 650 nm; 15 nm wide. Axial canal obscure. Basic helix obscure.

Biochemical properties

Virions contain 8.5 % nucleic acid.

Cytopathology

Virions found in leaves, mesophyll and epidermis; in cytoplasm. Inclusions present in infected cells; are unusual in shape; are masses of virions.

Taxonomy and relationships

Possible Carlavirus

Virus(es) with serologically related virions

Potato S virus.

Best tests for diagnosis

Chenopodium amaranticolor and Gomphrena globosa are susceptible.
