Nomenclature

Synonyms

camellia leaf yellow mottle virus, camellia infectious variegation virus (Milbrath and McWhorter, 1946; Gailhofer et al., 1988), camellia colour-breaking virus (Gailhofer et al., 1988), camellia variegation virus.

ICTV decimal code

79.0.P.3.DE.1

Host range and symptoms

Natural host range and symptoms

Symptoms persist, or vary seasonally, or disappear soon after infection. Symptoms chlorotic leaf flecks and flower breaking.
• Camellia japonica, C. sasanqua - chlorotic leaf flecks and flower breaking.

Transmission

Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by pollen.

Geographical distribution

Probably distributed worldwide (wherever camellias are grown).

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show chlorotic flecks in leaves and flower breaking.

Diagnostically susceptible host species and symptoms

• Camellia japonica, C. sasanqua - chlorotic flecks and mottle, flower breaking.

Maintenance and propagation hosts

Camellia japonica, C. sasanqua.

Assay hosts (Local lesions or Whole plants)

Camellia japonica (W), C. sasanqua (W).

Susceptible host species

• Camellia
• Camellia japonica
• Camellia sasanqua

Families containing susceptible hosts

• Theaceae (3/3)

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Particle morphology

Virions rod-shaped; of 120-170 nm; 30 nm wide. Axial canal obvious; 10 nm in diameter. Pitch of basic helix 10 nm.

Cytopathology

Virions found in leaves, mesophyll, petals and stamens; in cytoplasm.

Taxonomy and relationships

Possible varicosavirus
