Purification method

Makkouk et al. (1981).

Physical and biochemical properties

Particle morphology

Virions isometric; not enveloped; 28-30 nm in diameter; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 132 S.

Features of proteins

Virion protein(s) one; M_r 41000.

Cytopathology

Virions found in leaves; in cytoplasm and in chloroplasts (but possibly after chloroplast membranes disintegrate). Inclusions present in infected cells; are unusual in shape; multivesicular cytoplasmic inclusions. Other cellular changes: an increase in the volume of cytoplasm.

Taxonomy and relationships

Tombusvirus: Tombusviridae

Virus(es) with serologically related virions

Pelargonium leaf curl, tomato bushy stunt (strain BS-3) and petunia asteroid mosaic viruses.

Best tests for diagnosis

Host range, as a large number of indicator plants produce local lesions, and serology.
