Pea seed-borne
mosaic potyvirus
Index
Data collated by P. Fry, 1980. Revised 1984.
Nomenclature
Synonyms
pea fizzle top virus, pea leaf rolling virus, pea
leaf roll mosaic virus, pea leaf rolling mosaic virus.
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Pisum sativum; by Musil (1966).
Natural host range and symptoms
Symptoms disappear soon
after infection.
- Pisum sativum - transitory vein clearing, rosetting of stem
and branches, leaves dark green and leaflets folded adaxially, flowers malformed
and often sterile, pods small, few misshapen seeds.
Transmission
Transmitted by a vector; an insect;
Acyrthosiphon pisum, Aphis craccivora, A. fabae, Dactynotus escalanti,
Macrosiphum crataegarius, Rhopalosiphum padi; Aphididae. Transmitted in a
non-persistent manner. Virus transmitted by mechanical inoculation;
transmitted by seed (up to 100% in Pisum sativum, especially when testa
is split, but little seed transmission in Vicia faba, V. narbonensis and
V. pannonica).
Geographical distribution
Spreads in
the Central Asian region, the Eastern Asian region, and the North American
region; Australia and the UK. Found, but with no evidence of spread, in New
Zealand.
Experimental host range
Many (>9) families
susceptible.
Diagnostically susceptible host species and
symptoms
- Chenopodium amaranticolor - necrotic local
lesions.
- C. quinoa - chlorotic local lesions.
- Pisum
sativum - systemic stunting, vein clearing, leaf rolling.
- Vicia
faba - systemic vein chlorosis.
Maintenance and propagation
hosts
Lathyrus odoratus, Pisum sativum, Vicia faba.
Assay hosts (Local lesions or Whole plants)
Chenopodium amaranticolor, C.
quinoa.

usually flexuous; with a clear modal length; of 770 nm; 12 nm wide. Axial canal
obscure. Basic helix obscure; pitch of basic helix 3.4 nm.
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 154 S. Density 1.329 g cm-3
in CsCl.

Cytopathology
Virions found in roots in cortical
parenchyma and in mesophyll; in cytoplasm. Inclusions present in infected cells;
are pinwheels and unusual in shape; aggregates in tonoplasts; they contain
virions (in the aggregates).
