rice infectious gall virus.
ICTV decimal code
Host range and symptoms First reported
in Oryza sativa; from Indonesia and the Philippines; by Hibino et
al. (1977); Ling (1977); Shikata et al. (1977).
Natural host range and symptoms
- Oryza latifolia, O. nivara, O. sativa - stunting, enations on
veins of leaves and leaf sheaths, ragged leaves, flower suppression.
Transmitted by a vector; an insect;
Nilaparvata lugens; Delphacidae. Transmitted in a persistent manner.
Virus retained when the vector moults; multiplies in the vector; not transmitted
congenitally to the progeny of the vector; does not require a helper virus for
vector transmission; not transmitted by mechanical inoculation; not transmitted
by contact between plants; not transmitted by seed; not transmitted by pollen.
Spreads in Bangladesh, China,
India, Indonesia, Japan, Malaysia, the Philippines, Sri Lanka, Taiwan, and
Experimental host range
Few (<3) families susceptible.
Diagnostically susceptible host species and symptoms
- Oryza sativa cv. Taichung Native (TN-1) - pale
spindle-shaped enations on abaxial surfaces of leaves and leaf sheaths, twisted
and ragged leaves, dark green colour, suppressed flowering, infected plants
remain green and appear grassy after healthy plants have senesced.
Diagnostically insusceptible host species
aestivum, Saccharum spp.
Maintenance and propagation hosts

Properties of particles in sap
contains few virions (whole leaf sap), or contains many virions (in sap from
Virions isometric; not enveloped; 65
nm in diameter; angular in profile; without a conspicuous capsomere arrangement
(but with 12 "B" type spikes 8-10 nm long).
One sedimenting component in purified
Genome consists of RNA;
double-stranded. Total genome size 26.66 kb (pairs). Genome of 10 parts
(named S1-10); largest (or only) genome part the largest 3.9 kb (pairs); the
2nd largest 3.9 kb (pairs); the 3rd largest 3.8 kb (pairs); the 4th largest 3.8
kb (pairs); the 5th largest 2.75 kb (pairs); the 6th largest and other parts 2.3
kb (pairs; also 1.95, 1.90, 1.20 and 1.16 kb pairs). Additional factor required
for infectivity; as only the whole virion is infective.
Features of the genome
Non-genomic nucleic acid
not found in the virions.
Features of proteins
Virion protein(s) 8;
Mr 125000. Mr of 2nd largest 97000. Mr of 3rd
largest 66000. Mr of 4th largest 64000. Mr of 5th largest
48000. Mr of 6th largest and smaller, 43000 (also 36000 and 32000).
Genome replicates in cytoplasmic viroplasms.
Coat protein mRNA translated in the cytoplasm. Replication does not
depend on a helper virus.
Virions found in phloem enations; in
cytoplasm. Inclusions present in infected cells; are viroplasms; they contain
virions. Other cellular changes: cell enlargement and sometimes cell wall
Virus(es) with serologically unrelated virions
Sugarcane Fiji disease, maize rough dwarf, pangola stunt, rice
black-streaked dwarf, oat sterile dwarf, rice dwarf, rice gall dwarf and clover
wound tumor viruses.
