Nomenclature

Synonyms

solanum nigrum mosaic virus, solanum nodiflorum virus.

Acronym

SNMV

ICTV decimal code

67.0.1.0.006

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Solanum nodiflorum, S. nitidibaccatum, S. nigrum - leaf mottling and rugosity.

Transmission

Transmitted by a vector; an insect; Epilachna vigintioctopunctata pardalis (syn. E. sparsa), E. vigintisexpunctata vigintisexpunctata (syn. E. doryca australica) and E. guttatopustulata; Coleoptera. Virus not transmitted by seed.

Geographical distribution

Spreads in Australia (the east).

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Solanum nodiflorum - systemic leaf mottling and puckering.
• Nicotiana clevelandii - chlorotic local lesions; systemic vein chlorosis, mottling and puckering.
• Nicotiana debneyi - necrotic local lesions and small chlorotic ring local lesions; not systemic.

Maintenance and propagation hosts

Nicotiana clevelandii - for purification. Solanum nodiflorum - for culture and vector maintenance.

Assay hosts (Local lesions or Whole plants)

Nicotiana debneyi (L).

Susceptible host species

• Chenopodium quinoa
• Datura stramonium
• Gomphrena globosa
• Nicandra physalodes
• Nicotiana benthamiana
• Nicotiana clevelandii
• Nicotiana debneyi
• Nicotiana glutinosa
• Nicotiana tabacum
• Petunia × hybrida
• Solanum melongena
• Solanum nigrum
• Solanum nitidibaccatum
• Solanum nodiflorum
• Solanum rostratum
• Tetragonia tetragonioides

Families containing susceptible hosts

• Chenopodiaceae (1/1)
• Solanaceae (13/13)
• Tetragoniaceae (1/1)

Sources of host-range data

Greber (1981); Jones and Mayo (1984).

Physical and biochemical properties

Properties of particles in sap

TIP: 90 °C. LIV: 365 days (at 2ºC and 7 years at -20ºC). DEP: log₁₀ minus 5. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains many virions.

Purification method

Greber (1981); Hollings et al. (1979); Kiberstis and Zimmern (1984).

Particle morphology

Virions isometric; not enveloped; 28-30 nm in diameter; angular in profile.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 114 S (Hollings et al., 1979). Density 1.35 g cm^-3 in CsCl.

Biochemical properties

Genome consists of RNA; single-stranded; linear. Total genome size 4.2 kb. Genome unipartite; largest (or only) genome part 4.2 kb. Genomic nucleic acid isolated by Gould and Hatta (1981).

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• J02386 Em(40)_vi:NOR2 Gb(84)_vi:MSNR2 solanum nodiflorum mottle virus (circular viroid-like) RNA2. 4/90 377bp. 1 sequence.

Features of the genome

Non-genomic nucleic acid found in the virions; is satellite RNA (of 2 species, (RNA-2 and RNA-3), which are similar in size (c. 0.37 kb) but one is circular (RNA-2) the other linear (Gould et al., 1981; Jones and Mayo, 1984)).

Features of proteins

Virion protein(s) one; M_r 31000; coat protein (Hollings et al., 1979; Greber, 1981; Chu and Francki, 1983).

Replication

Replication does not depend on a helper virus. Acts as helper for a satellite RNA (Some of the isolates of the virus have no satellite RNA; Jones and Mayo, 1984).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm and in nuclei. Inclusions present in infected cells; are crystals in the cytoplasm, membranous bodies, and unusual in shape; long tubules or rod structures.

Taxonomy and relationships

Sobemovirus

Virus(es) with serologically related virions

Velvet tobacco mottle virus (Randles et al., 1981; Chu and Francki, 1983).

Additional comments on relationships

No serological relationship was found to 53 other viruses with isometric virions (Hollings et al., 1979).
