ICTV decimal code

57.0.3.0.006

Host range and symptoms

Natural host range and symptoms

Symptoms vary seasonally. Symptoms mosaic.
• Triticum aestivum - mosaic; chlorotic to necrotic streaks.

Transmission

Transmitted by a vector; a fungus; Polymyxa graminis probably; Plasmodiophorales. Not transmitted by Macrosiphum akebiae, Onychiurus matsumotoi, O. watanabei. Virus transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Ecology and control

Studies reported by Ikata and Kawai (1940); Saito et al. (1964).

Geographical distribution

Spreads in Canada, China, France, Japan, Korea D.P.R. (North), and Korea Republic.

Experimental host range

Physical and biochemical properties

Properties of particles in sap

TIP: less than 50 °C. LIV: 1 days. DEP: log₁₀ minus 2-3. Leaf sap contains few virions.

Purification method

Usugi and Saito (1976).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with clear modal lengths (two); of 275-300 nm, or 575-600 nm; 13-14 nm wide. Axial canal obscure.

Physical properties

Two sedimenting components in purified preparations. Density 1.281 g cm^-3 in CsCl. A₂₆₀/A₂₈₀ ratio 1.14.

NCBI sequence data (Entrez search)

Cytopathology

Virions found in all parts of the host plant; in cytoplasm. Inclusions present in infected cells; are amorphous X-bodies, membranous bodies, and pinwheels; they do not contain virions.

Taxonomy and relationships

Bymovirus: Potyviridae

Virus(es) with serologically related virions

Barley yellow mosaic and rice necrosis mosaic viruses.
