Physical and biochemical properties

Properties of particles in sap

TIP: 85-90 °C. LIV: 23 days. DEP: log₁₀ minus 6-7. Leaf sap contains many virions.

Purification method

Bock et al. (1981).

Particle morphology

Virions isometric; not enveloped; 33 nm in diameter; rounded in profile; with a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 126-127 S. Density 1.361 g cm^-3 in CsCl.

Biochemical properties

Virions contain 20 % nucleic acid (estimated from bouyant density in CsCl and A₂₆₀/A₂₈₀); 80 % protein.

Genome consists of RNA; single-stranded. Total genome size 4.5-4.7 kb. Genome unipartite; largest (or only) genome part 4.5-4.7 kb.

Features of proteins

Virion protein(s) one; M_r 42000; coat protein. Method of preparation: Bock et al. (1981).

Taxonomy and relationships

Possible Carmovirus: Tombusviridae

Virus(es) with serologically unrelated virions

44 other viruses, including eight tombus- or carmoviruses (Bock et al., 1981).
