Nomenclature

Acronym

CoRSV

Strains

Coffee ringspot from the Philippines is reported to be seed-borne, that from Brazil is not.

ICTV decimal code

62.U.P.0.011

Host range and symptoms

Natural host range and symptoms

Symptoms persist (while viruliferous mites present).
• Coffea arabica - chlorotic lesions.

Transmission

Transmitted by a vector; a mite; Tenuipalpidae: Brevipalpus phoenicis. Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Spreads in Brazil and the Philippines.

Experimental host range

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

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, C. quinoa - necrotic local lesions.
• Coffea arabica - chlorotic spots on leaves about 40 days after infestation with viruliferous mites.

Diagnostically insusceptible host species

Gomphrena globosa, Cucumis sativus, Phaseolus vulgaris, Nicotiana glutinosa, N. tabacum.

Physical and biochemical properties

Properties of particles in sap

TIP: 70-75 °C. LIV: 19-22 days at 4ºC. DEP: log₁₀ minus 4-5.

Particle morphology

Virions rhabdo- or bullet-shaped; enveloped; with a clear modal length; of 178-224 nm (in thin sections); 59-76 nm wide (in thin sections). Axial canal obvious; 8 nm in diameter.

Cytopathology

Virions found in lesions of leaves and in fruit pulp; in nuclei and in the perinuclear space.

Taxonomy and relationships

Possible Nucleorhabdovirus: Rhabdoviridae
