Host range and symptoms

Natural host range and symptoms

Symptoms vary cyclically over a few weeks and vary seasonally.
• Glycine clandestina, G. tabacina - green mosaic, leaves malformation.

Transmission

Virus transmitted by mechanical inoculation.

Geographical distribution

Sources of host-range data

Bowyer et al. (1980).

Physical and biochemical properties

Properties of particles in sap

TIP: 55-60 °C. LIV: 7-8 days. DEP: log₁₀ minus 4-5. Leaf sap contains many virions.

Purification method

Bowyer et al. (1980).

Particle morphology

Virions isometric; not enveloped; 28 nm in diameter; angular in profile; without a conspicuous capsomere arrangement.

Physical properties

Three sedimenting components in purified preparations; sedimentation coefficient of the fastest 130 S (B); of the other(s) 60 S (T), or 103 S (M). A₂₆₀/A₂₈₀ ratio 1.63 (M), or 1.75 (B).

Biochemical properties

Virions contain 38.6 % nucleic acid (B), or 26.4 % nucleic acid (M), or 0 % nucleic acid (T); 63.2 % protein (B), or 73.6 % protein (M), or 100 % protein (T).

Features of proteins

Virion protein(s) two (major and 1 minor); M_r of the largest 42000. M_r of 2nd largest 21500. M_r of 3rd largest 19000. Method of preparation: Bowyer et al. (1980).

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in mesophyll; in cytoplasm. Inclusions present in infected cells; are unusual in shape; large aggregates, often in crystalline array, associated with amorphous, membrane-bound bodies; they contain virions. Other cellular changes: cytoplasmic vesiculation.

Taxonomy and relationships

Comovirus: Comoviridae

Virus(es) with serologically related virions

Broad bean stain, broad bean true mosaic and squash mosaic viruses to both strains; cowpea mosaic (Sb and Ark), bean pod mottle and red clover mottle viruses are related to the GW strain.
