Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Ullucus tuberosus - systemic leaf mottling and malformation.

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants.

Geographical distribution

Spreads in Bolivia and Peru.

Experimental host range

Sources of host-range data

Brunt et al. (1982).

Physical and biochemical properties

Properties of particles in sap

TIP: 65 °C (in Nicotiana clevelandii sap). LIV: 8-16 days. DEP: log₁₀ minus 5. Leaf sap contains few virions.

Purification method

Brunt et al. (1982).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 752 nm; 12 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 150 S.

Biochemical properties

Virions contain 5 % nucleic acid; 95 % protein.

Genome consists of RNA; single-stranded. Total genome size 9 kb. Genome unipartite; largest (or only) genome part 9 kb.

Features of the genome

Non-genomic nucleic acid not found in the virions.

Features of proteins

M_r 32000; coat protein.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in all parts of the host plant; in cytoplasm. Inclusions present in infected cells; are pinwheels; they do not contain virions.
