Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Glycine max - systemic mosaic, stunting.
• Lablab purpureus - systemic vein-clearing.
• Phaseolus vulgaris - chlorotic local lesions. systemic vein clearing, mottling, leaf curling.
• Vigna unguiculata - systemic infection, no symptoms.

Transmission

Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Spreads in Japan.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

Physical and biochemical properties

Properties of particles in sap

TIP: 85-90 °C. LIV: 1 days. DEP: log₁₀ minus 3-4. Leaf sap contains few virions.

Purification method

Iwaki et al. (1984).

Particle morphology

Virions isometric; not enveloped; 50 nm in diameter; rounded in profile; with a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations.

Biochemical properties

Genome consists of DNA; double-stranded; circular. Total genome size 8.175 kb (pairs). Genome unipartite; largest (or only) genome part 8.175 kb (pairs). Genomic nucleic acid isolated by Hibi et al. (1986). Base composition of ds genome 28 % (G + C). Infectivity decreased when deproteinised with proteases; retained when deproteinised with phenol or detergent. Nucleotide sequence references: Verver et al. (1986).
