ICTV decimal code
Host range and symptoms
First reported
in Prunus persica; from the U.S.A.; by Cochran and Hutchins (1941).
Natural host range and symptoms
Symptoms persist (in some
hosts), or disappear soon after infection (in some hosts).
- Prunus cerasus - dark necrotic lines and rings, shotholes,
recovery.
- Prunus persica - brown lines and rings, recovery.
- Rosa (rose) - chlorotic lines and rings, oak leaf patterns, no
recovery.
- Prunus (plum) - chlorotic lines and rings only some
strains.
- Prunus (almond) - bright mosaic.
- Humulus
(hops) - no symptoms.
- Cucumis sativus - chlorotic local
lesions, systemic necrosis and severe stunting.
Transmission
Transmitted by means not involving a vector.
Virus transmitted by mechanical inoculation; transmitted by grafting; not
transmitted by contact between plants; transmitted by seed (to over 80% in
Prunus pennsylvanica but much less in peach); transmitted by pollen to
the seed and transmitted by pollen to the pollinated plant.
Geographical distribution
Probably distributed worldwide.
Experimental host range
Many (>9) families
susceptible.
Diagnostically susceptible host species and
symptoms
- Cucumis sativus - large yellow chlorotic local
lesions in cotyledons, growing point stunted.
- Momordica balsamina
- necrotic local lesions.
- Cyamopsis tetragonoloba - dark
necrotic local lesions.
- Chenopodium quinoa - systemic mottle.
- Prunus serrulata - local necrosis and gumming at site of grafts.
- Lupinus albus - systemic mottle.
- Helianthus annuus -
systemic chlorotic lines and rings.
- Cassia tora - local and
systemic ringspotting.
Diagnostically insusceptible host species
Tithonia speciosa, Lagenaria siceraria, Nepeta cataria, Crotalaria
spectabilis, Plantago virginica.
Maintenance and propagation hosts
Cucumis sativus, Catharanthus roseus.
Assay hosts
(Local lesions or Whole plants)
Momordica balsamina (L), Cucumis sativus (W),
Cyamopsis tetragonoloba (L).

purified preparations; sedimentation coefficient of the fastest 95 S (B);
of the other(s) 72 S (T), or 90 S (M; the B and M components
required for infection). Density 1.35 g cm-3 in CsCl (unfixed).
A260/A280 ratio 1.56 (B).
Biochemical properties
Virions contain 16 % nucleic acid;
84 % protein; 0 % lipid.
Genome consists of RNA; single-stranded. Total genome size 8.056 kb.
Genome of three parts; largest (or only) genome part the largest 3.662 kb; the
2nd largest 2.507 kb; the 3rd largest 1.887 kb. Genomic nucleic acid isolated by
Loesch and Fulton (1975). Base composition 27 % G; 25 % A; 21 % C; 27 % U.
Additional factor required for infectivity.

Features of the genome
Non-genomic nucleic acid
found in the virions; is subgenomic mRNA; for the coat protein.
Sub-genomic mRNA found in infected cells.
Features of proteins
Mr 25000. Method of
preparation: Gonsalves and Fulton (1977).
Replication
Replication does not depend on a helper
virus.
Taxonomy and
relationships
Virus(es) with serologically related virions
Virions of prunus necrotic ringspot virus share some serological
determinants with those of apple mosaic.
Virus(es) with serologically
unrelated virions
Tobacco streak, asparagus 2,
citrus leaf rugose, citrus variegation, elm mottle, Tulare apple mosaic and
prune dwarf viruses.
