Transmission
Transmitted by a vector (5/5); an insect
(5/5); Delphacidae (5/5). Transmitted in a persistent manner (5/5). Virus
retained when the vector moults (5/5); multiplies in the vector (5/5);
transmitted congenitally to the progeny of the vector (2/4), or not transmitted
congenitally to the progeny of the vector (2/4); does not require a helper virus
for vector transmission (1/1); transmitted by mechanical inoculation (2/5), or
not transmitted by mechanical inoculation (3/5); not transmitted by grafting
(2/2); not transmitted by contact between plants (3/3); not transmitted by seed
(4/4); not transmitted by pollen (3/3).
Experimental host range

(5/5).

Physical and
biochemical properties
Properties of particles in sap
TIP: 60
°C. LIV: 6-6.5-7 days. DEP: log10 minus 5-6 (1/1). Leaf sap contains few
virions (4/5), or contains many virions (4/5).
Particle morphology
Virions isometric; not enveloped
(5/5); 54-67.5-80 nm in diameter; rounded in profile (5), or angular in profile
(3); with a conspicuous capsomere arrangement (2/4), or without a conspicuous
capsomere arrangement (2/4).
Physical properties
One sedimenting component in purified
preparations (2/4), or two sedimenting components in purified preparations
(3/4), or three sedimenting components in purified preparations (1/4), or four
sedimenting components in purified preparations (1/4); sedimentation coefficient
400 S.
Biochemical properties
Virions 0 % lipid.
Genome consists of RNA; double-stranded; linear (4/4). Total genome size
23.89-26.25-28.91 kb. Genome of 10 parts; largest (or only) genome part
3.405-3.95-4.4 kb; the 2nd largest 3.2-3.459-3.9 kb; the 3rd largest
3.15-3.379-3.7 kb; the 4th largest 2.6-3.231-3.7 kb; the 5th largest
2.55-2.975-3.3 kb; the 6th largest and other parts 2.293-2.488-2.9 kb.
Additional factor required for infectivity (2/2).
Features of the genome
Non-genomic nucleic acid
not found in the virions (2/2).
Features of proteins
Virion protein(s) three (1/2),
or six (1/2); Mr 138900-143200-149900. Mr of 2nd largest
124900-125900-128900. Mr of 3rd largest 36000-80250-122900.
Mr of 4th largest 110900. Mr of 5th largest 97000.
Mr of 6th largest and smaller, 64000.
Replication
Genome replicates in cytoplasm (1/3), or in
cytoplasmic viroplasms (2/3). Replication does not depend on a helper virus
(3/3).
Cytopathology
Virions found in cytoplasm, or in cell
vacuoles (1). Inclusions present in infected cells (5/5); are crystals in the
cytoplasm (2), or crystals in the nucleus (1), or viroplasms (5), or unusual in
shape (4); they contain virions.
Taxonomy and
relationships
