pepino latent virus (Dolby and Jones, 1988; Jones
et al., 1980).
ICTV decimal code
Host range and symptoms First reported
in Solanum tuberosum; from the Netherlands; by de Bruyn Ouboter (1952);
Natural host range and symptoms
- Solanum tuberosum - causes few or no symptoms, but decreases
yield of potato tubers by up to 20%.
Transmitted by a vector; an insect; Myzus
persicae. Isolates differ in their transmissibility by Myzus persicae
(Bode and Weidemann, 1970); an isolate from the U.S. seedling 41956 could not be
transmitted under conditions in which the related potato virus M was transmitted
(Wetter and Völker, 1960); Aphididae. Transmitted in a non-persistent
manner. Virus transmitted by mechanical inoculation; not transmitted by seed.
Ecology and control
Studies reported by Kassanis (1957).
Infected potato, cv. King Edward has been freed from potato M, S and other
viruses by apical meristem culture.
Probably distributed worldwide (in cultivated varieties of potato).
Experimental host range
Few (<3) families susceptible.
Diagnostically susceptible host species and symptoms
- Chenopodium amaranticolor, C. quinoa, C. album -
chlorotic local lesions which, in older leaves, may develop a green halo; not
- Solanum rostratum - small necrotic local lesions,
systemic necrotic spots.
- Nicotiana debneyi - symptomless in
inoculated leaves; systemic veinclearing and mottling and necrosis.
- Cyamopsis tetragonoloba - small brown necrotic local lesions in
cotyledons, not systemic.
Diagnostically insusceptible host species
Maintenance and propagation hosts
Assay hosts (Local lesions or Whole plants)
Chenopodium amaranticolor (L); Chenopodium quinoa (L);
Chenopodium album (L).

Features of the genome
Features of the genome: the
sequence of the 3´ 3553 nucleotides of the genomic RNA has been determined;
six ORF's recognised which encode for polypeptides, respectively of Mr 10734,
32515, 7222, 11803, 25092 and 41052.
Features of proteins
Replication does not depend on a helper
Virus(es) with serologically related virions
Carnation latent, potato M, chrysanthemum B, passiflora latent,
cactus 2 and red clover vein mosaic viruses, but distantly.
Best tests for diagnosis
potato cultivars potato S virus is found with the related potato M carlavirus.
Potato S virus may be obtained from the mixture by inoculating Nicotiana
debneyi which is systemically infected by potato S virus, but only locally
by potato M virus.
