Virions isometric; not enveloped; 33 nm in diameter.

Biochemical properties

Genome consists of RNA; single-stranded. Total genome size 4.8 kb. Genome unipartite; largest (or only) genome part 4.8 kb.

Features of proteins

Virion protein(s) one; M_r 35800; coat protein.

Cytopathology

Virions found in cytoplasm. Other cellular changes: few peroxisomal vesicles induced; endoplasmic reticulum adjacent to peroxisomes.

Taxonomy and relationships

Possible Tombusvirus: Tombusviridae

Virus(es) with serologically unrelated virions

Artichoke mottled crinkle, carnation Italian ringspot, cymbidium ringspot, cucumber necrosis, eggplant mottled crinkle, grapevine Algerian latent, Lato River, pepper Moroccan, Neckar River, petunia asteroid mosaic, pelargonium leaf curl and tomato bushy stunt tombusviruses, and 15 carmoviruses.

Additional comments on relationships

In Northern blot hybridization tests, the genomic RNA showed some homology with the genomic RNAs of grapevine Algerian latent, petunia asteroid mosaic and cymbidium ringspot tombusviruses.
