Index
Data collated by T. Omura, 1984. Revised 1989.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Oryza sativa; from Thailand; by Omura et al. (1982).
Natural host range and symptoms
Symptoms persist.
- Oryza sativa - stunting, gall formation and dark green
leaves.
Transmission
Transmitted by a vector; an insect;
Nephotettix nigropictus, N. cincticeps, N. malayanus, N. virescens, Recilia
dorsalis; Cicadellidae. Transmitted in a persistent manner. Virus retained
when the vector moults; multiplies in the vector; transmitted congenitally to
the progeny of the vector; not transmitted by mechanical inoculation; not
transmitted by contact between plants; not transmitted by seed; not transmitted
by pollen.
Geographical distribution
Spreads in China. Found,
but with no evidence of spread, in Malaysia and Thailand.
Experimental host range
Few (<3) families susceptible.
Diagnostically susceptible host species and symptoms
- Avena sativa, Hordeum vulgare, Lolium multiflorum, Secale
cereale, Triticum aestivum - stunting, gall formation and leaf
discoloration.
Maintenance and propagation hosts
Assay hosts (Local lesions or Whole plants)
Avena sativa (W), Hordeum
vulgare (W), Oryza sativa (W), Secale cereale (W), Triticum
aestivum (W).

Features of proteins
Virion protein(s) 7;
Mr of the largest 183000. Mr of 2nd largest 165000.
Mr of 3rd largest 150000. Mr of 4th largest 143000.
Mr of 5th largest 120000. Mr of 6th largest and smaller,
45000 and 56000. Method of preparation: Omura (1985).
Cytopathology
Virions found in phloem; in cytoplasm and
in cell vacuoles. Inclusions present in infected cells; are viroplasms; they do
not contain virions (but incomplete virion-like particles are frequently
observed).
Taxonomy and
relationships
Virus(es) with serologically unrelated virions
Rice dwarf and clover wound tumour viruses. The antiserum against
SDS-dissociated rice dwarf virus cross-reacted with one peptide component of
rice gall dwarf virus when tested by immunoblotting.
