Nomenclature

Synonyms

common pea mosaic virus.

ICTV decimal code

57.0.1.0.009

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Pisum sativum, Pisum arvense, Trifolium pratense, Vicia faba, Trifolium incarnatum, Lathyrus odoratus - marble or yellow mosaic, stunting, delayed unfolding of leaflets.

Transmission

Transmitted by a vector; an insect; 15 spp. including Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Probably distributed worldwide. Spreads in China.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - chlorotic local lesions, then systemic mosaic, leaf malformation, apical necrosis.
• C. quinoa - chlorotic local lesions.
• Lathyrus odoratus, Lupinus angustifolius, Pisum arvense, P. sativum, Trifolium pratense - systemic mosaic.
• T. subterraneum - systemic mosaic, vein banding, stunting.
• Vicia faba - systemic marble mosaic.

Diagnostically insusceptible host species

most Phaseolus vulgaris cvs.

Maintenance and propagation hosts

Pisum arvense, P. sativum, Vicia faba.

Sources of host-range data

Physical and biochemical properties

Properties of particles in sap

TIP: 55-60 °C. LIV: 1-2 days. DEP: log₁₀ minus 3-4. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains few virions.

Purification method

Moghal and Francki (1976).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 785-800 nm; 13 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 140 S. Density 1.321 g cm^-3 in CsCl.

Biochemical properties

Virions contain 5.5-6 % nucleic acid; 94-94.5 % protein; 0 % lipid.

Genome consists of RNA; single-stranded; linear; unipartite.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• S71232 Gb(84)n:S71232 3´ end: polyprotein pea mosaic potyvirus PMV-I, I, Genomic RNA, 1035 nt. 9/94 1,035bp.

Features of proteins

Virion protein(s) one; M_r 33000.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in mesophyll and epidermis; in cytoplasm. Inclusions present in infected cells; are crystals in the cytoplasm, or crystals in the nucleus (associated with the nucleolus, 2-3 m), or unusual in shape; and granular bodies, 10-30 m; they contain virions (in the cytoplasm only). Other cellular changes: chloroplast damage.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Bean yellow mosaic virus is closely related; bean common mosaic and clover yellow vein viruses are distantly related.

Comments and References

General comments

Synonym of bean yellow mosaic potyvirus.
