Sources of host-range data

Physical and biochemical properties

Properties of particles in sap

TIP: 80-85 °C. LIV: 60 days (or more). DEP: log₁₀ minus 5-6. Electron microscopy: use 2% UA for negative staining.

Purification method

Behncken and Dale (1984).

Particle morphology

Virions isometric; not enveloped; 30 nm in diameter; rounded in profile; with a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 138 S.

Biochemical properties

Virions contain 20 % nucleic acid.

Genome consists of RNA; single-stranded. Total genome size 4.2 kb. Genome unipartite; largest (or only) genome part 4.2 kb.

Features of proteins

Virion protein(s) one (plus 2 fragments); M_r 39000 (plus two of 37500 and 31000); coat protein. Method of preparation: Dale and Gibbs (1976).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm and in nuclei (especially associated with the nucleolus and cytoplasmic invaginations of chloroplasts). Other cellular changes: vesicles in peroxisomes closely associated with chloroplasts. Number of vesicles are variable and are located around microbodies.

Taxonomy and relationships

Possible Carmovirus: Tombusviridae

Virus(es) with serologically unrelated virions

Artichoke mottled crinkle, carnation Italian ringspot, cymbidium ringspot, galinsoga mosaic, pelargonium leaf curl, petunia asteroid mosaic, saguaro cactus, tephrosia symptomless, tomato bushy stunt and turnip crinkle viruses.
