symptoms
Natural host range and symptoms
Symptoms
persist (6/7), or vary seasonally (1/7), or disappear soon after infection
(1/7).
Transmission
Transmitted by a vector (7/7); an insect
(7/7); Aphididae (3/7), or Delphacidae (4/7). Transmitted in a persistent manner
(6/6). Virus retained when the vector moults (5/5); multiplies in the vector
(5/5); transmitted congenitally to the progeny of the vector (3/5), or not
transmitted congenitally to the progeny of the vector (2/5); transmitted by
mechanical inoculation (9/15), or not transmitted by mechanical inoculation
(6/15); transmitted by grafting (3/3); not transmitted by contact between plants
(3/3); not transmitted by seed (8/8); not transmitted by pollen (2/2).
Experimental host range
Several (3-9) families
susceptible (4/11), or few (<3) families susceptible (7/11).

Physical and
biochemical properties
Properties of particles in sap
TIP:
50-52.78-60 °C. LIV: 0.1-1.328-5 days. DEP: log10 minus 2 (2/7), or 3-4
(3/7), or 5-6 (1/7). Infectivity of sap decreased by treatment with di-ethyl
ether (3/3). Leaf sap contains few virions (8/9), or contains many virions
(2/9).
Particle morphology
Virions rhabdo- or
bullet-shaped; enveloped (12/12); usually straight (3/3); with a clear modal
length (12/13), or with no clear modal length (1/13); of 100-278.2-360 nm;
42-63.32-130 nm wide. Axial canal obvious (5/5); 14-20.5-35 nm in diameter.
Basic helix obvious (6/7), or obscure (1/7); pitch of basic helix 4.2-4.633-5.5
nm.
Physical properties
One sedimenting component in purified
preparations (5/5); sedimentation coefficient 704-839.3-940 S. Density
1.19-1.194-1.2 g cm-3 in sucrose.
Biochemical properties
Genome consists of RNA (5/5);
single-stranded (5/5); linear (1/1). Total genome size 10.5-12.34-14 kb.
Genome unipartite (3/3); largest (or only) genome part 10.5-12.34-14 kb. Base
composition 16.3 % G; 30.3 % A; 16.7 % C; 36.6 % U. Infectivity lost when
deproteinised with phenol or detergent (2/2).
Features of the genome
Non-genomic nucleic acid
found in the virions (1/1); is rRNA (1/1). Sub-genomic mRNA
found in infected cells (1/1).
Features of proteins
Virion protein(s) three (1/3),
or five (1/3), or six (1/3); Mr 50000-108200-189900. Mr of
2nd largest 49000-62160-76000. Mr of 3rd largest 20000-40160-54000.
Mr of 4th largest 38000-39000-40000. Mr of 5th largest
19000. Virion proteins glycosylated (4/4).
Replication
Genome replicates in cytoplasm (1/1).
Replication does not depend on a helper virus (3/3).
Cytopathology
Virions found in cytoplasm, or in the
perinuclear space (1). Inclusions present in infected cells (5/7), or absent
from infected cells (2/7); are membranous bodies (2/5), or viroplasms (3/5), or
unusual in shape (1/5); they contain virions (2/4), or they do not contain
virions (2/4).
