Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms irregular chlorotic mottle and distortion of leaves, especially terminal leaves.
• Prunus avium - irregular chlorotic mottling and distortion of foliage, especially terminal leaves.

Transmission

Transmitted by a vector; a mite; Eriophyes inaequalis; Eriophyidae. Virus transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in Belgium, Canada, the former Czechoslovakia, Italy, Poland, Romania, South Africa, and the USA.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - local lesions, systemic leaf distortion, epinasty, chlorosis and stunting.
• C. quinoa - local chlorotic spots and stunting.

Diagnostically insusceptible host species

Physical and biochemical properties

Properties of particles in sap

TIP: 50-55 °C. LIV: 1 days. Leaf sap contains many virions.

Purification method

James and Mukerji (1993).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 760 nm; 10.2 nm wide. Axial canal obscure. Basic helix obvious; pitch of basic helix 3.1 nm.

Physical properties

One sedimenting component in purified preparations. A₂₆₀/A₂₈₀ ratio 1.62.

Biochemical properties

Genome consists of RNA; single-stranded; linear. Total genome size 8.2 kb. Genomic nucleic acid isolated by James and Mukerjee, 1993.

Features of proteins

Virion protein(s) one; M_r 20500; coat protein.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves.

Taxonomy and relationships

Trichovirus

Virus(es) with serologically unrelated virions

Apple chlorotic leafspot virus, several grapevine viruses (GLRV-1, GLRV-3, NY-1 and GVA) and heracleum latent virus.

Best tests for diagnosis

ELISA, western blot using mAbs.
