Nomenclature

Synonyms

alfalfa latent virus, Steinklee Virus, Wisconsin pea streak virus, probably pea streak New Zealand virus (Bos, 1964; Chamberlain, 1954).

Acronym

PeSV

ICTV decimal code

14.0.1.0.023

Host range and symptoms

Natural host range and symptoms

Symptoms persist, or disappear soon after infection (in the glasshouse).
• Medicago sativa - symptomless.
• Pisum sativum - necrotic lesions or streaks.

Transmission

Transmitted by a vector; an insect; Acyrthosiphon pisum; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Spreads in the Eurasian region; Canada and the USA.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Pisum sativum - inoculated leaves symptomless, systemic necrosis, vein banding, reddening.
• Vicia faba cv. Bell - necrotic local lesions, then systemic necrosis, necrotic spots and streaks.
• Cassia occidentalis - necrotic or chlorotic local lesions only.

Maintenance and propagation hosts

Pisum sativum, Vicia faba.

Comments on host-range

The isolate orginally described as alfalfa latent virus induces milder symptoms and infects fewer species.

Sources of host-range data

Bos (1973); Edwardson and Christie (1986); Hampton et al. (1978); Thornberry (1966).

Physical and biochemical properties

Properties of particles in sap

TIP: 70 °C. LIV: 7 days. DEP: log₁₀ minus 6. Leaf sap contains many virions.

Purification method

Veerisetty and Brakke (1978).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 630 nm; 13.5 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 160 S.

Biochemical properties

Virions contain 5 % nucleic acid; 95 % protein.

Genome consists of RNA; single-stranded. Total genome size 7 kb. Genome unipartite; largest (or only) genome part 7 kb. Infectivity retained when deproteinised with phenol or detergent.

Features of the genome

Non-genomic nucleic acid not found in the virions. Sub-genomic mRNA not found in infected cells.

Features of proteins

Virion protein(s) two; M_r of the larger 29000. M_r of 2nd largest 24000.

Cytopathology

Virions found in mesophyll; in cytoplasm. Inclusions present in infected cells; are unusual in shape; vacuolated, paracrystalline and banded bodies; they contain virions. Other cellular changes: cells and their organelles deteriorate and endoplasmic reticulum increases.

Taxonomy and relationships

Carlavirus

Virus(es) with serologically unrelated virions

Red clover vein mosaic, potato M, potato S, hop mosaic, hop latent and American hop latent viruses.
