Data collated by A. Varma, 1984.
temple tree mosaic virus, champa mosaic virus.
Ald (Allahabad), Del (Delhi).
ICTV decimal code
Host range and symptoms First reported
in Plumeria acutifolia, P. alba; from India and Australia; by Francki
et al. (1971); Varma and Gibbs (1978).
Natural host range and symptoms
- Plumeria acutifolia - mosaic, ringspots, vein banding,
- P. alba - ringspots, leaf malformation, necrosis.
Transmitted by means not involving a vector.
Virus transmitted by mechanical inoculation.
Spreads in Australia, India, and Kenya.
Experimental host range
Several (3-9) families
Diagnostically susceptible host species and
- Datura stramonium - chlorotic or black
necrotic local lesions; most strains not systemic.
glutinosa - chlorotic local lesions, not systemic.
tabacum cvs Samsun, Virginia Gold, White Burley - chlorotic or necrotic
ringspots, then systemically when grown at 35ºC.
- Nicotiana ×
edwardsonii - faint chlorotic lesions which become necrotic when plants
are grown at 35ºC. Not systemic.
Chenopodium amaranticolor, Cucumis sativus, Phaseolus
Maintenance and propagation hosts
Assay hosts (Local
lesions or Whole plants)
Susceptible host species
Families containing susceptible hosts
Comments on host-range
high temperatures for replication. More species become infected at temperatures
above 25ºC than below. Symptoms appear in 3-6 days at 35ºC, but
after 2 weeks or more at 22ºC.

Properties of particles in sap
°C. LIV: 70 days (or more). DEP: log10 minus 5. Leaf sap contains many
Virions rod-shaped; not enveloped;
usually straight; with a clear modal length; of 297 nm; 17 nm wide. Axial canal
One sedimenting component in purified
preparations; sedimentation coefficient 188 S.
Features of proteins
Virion protein(s) one. Method of
preparation: Francki et al. (1971). Amino acid composition: Francki et
Replication does not depend on a helper
Virions found in mesophyll; in cytoplasm.
Inclusions present in infected cells; are crystals in the cytoplasm; they
Virus(es) with serologically related virions
Cucumber green mottle mosaic and sunn-hemp mosaic viruses are closely
related; tobacco mosaic virus-type strain, tobacco mild green mosaic (U2),
tomato mosaic and ribgrass mosaic viruses are more distantly related (Francki
et al., 1971). Nucleic hybridization tests have confirmed the relatedness
of tomato mosaic and tobacco mild green mosaic viruses (Palukaitis and Symons,
1980; Palukaitis et al., 1981).
