Symptoms
persist (5/5), or vary cyclically over a few weeks (1/5).
Transmission
Transmitted by a vector (9/9); an insect
(9/9); Cicadellidae (1/9), or Delphacidae (8/9). Transmitted in a persistent
manner (9/9). Virus retained when the vector moults (6/6); multiplies in the
vector (5/5); transmitted congenitally to the progeny of the vector (4/5), or
not transmitted congenitally to the progeny of the vector (1/5); transmitted by
mechanical inoculation (1/8), or not transmitted by mechanical inoculation
(7/8); not transmitted by contact between plants (6/6); not transmitted by seed
(5/5); not transmitted by pollen (2/2).
Experimental host range
Few (<3) families susceptible
(5/5).

Physical and
biochemical properties
Properties of particles in sap
TIP:
50-52.5-55 °C. LIV: 0.5 days. DEP: log10 minus 2-4 (1/2). Leaf sap contains
few virions (1/3), or contains many virions (2/3).
Particle morphology
Virions filamentous (5/6), or
rhabdo- or bullet-shaped (1/6); not enveloped (5/5); usually flexuous
(3/3); with no clear modal length (2/2); of 950-1150-1350 nm; 3-5.2-8 nm wide.
Axial canal obvious (1/2), or obscure (1/2). Basic helix obvious (1/1).
Physical properties
One sedimenting component in purified
preparations (3/6), or two sedimenting components in purified preparations
(1/6), or three sedimenting components in purified preparations (2/6), or four
sedimenting components in purified preparations (2/6); sedimentation coefficient
87-137.5-187 S; of the other(s) 68-74-80 S. Density
1.28-1.283-1.288 g cm-3 in CsCl. Isoelectric point pH 4.5.
Biochemical properties
Virions contain 5.2-9.733-12 %
nucleic acid; 88-91.4-94.8 % protein; 0 % lipid.
Genome consists of RNA (4/4); single-stranded (4/4); linear (4/4). Total
genome size 15.46-17.21-18.6 kb. Genome of four parts (3/4), or of five parts
(1/4); largest (or only) genome part 4.39-8.077-9.8 kb; the 2nd largest
3.5-3.63-3.94 kb; the 3rd largest 2.3-2.7-3.64 kb; the 4th largest
1.99-2.462-3.49 kb; the 5th largest 1.32 kb. Base composition 18.1 % G; 26.3 %
A; 17.8 % C; 37.8 % U. Additional factor not required for infectivity (1/1).
Features of proteins
Cytopathology
Virions found in cytoplasm (5/5), or in
nuclei (1/5). Inclusions present in infected cells (6/6); are crystals in the
cytoplasm (3/6), or crystals in the nucleus (1/6), or amorphous X-bodies
(3/6), or unusual in shape (2/6); they contain virions (2/5), or they do not
contain virions (3/5).
Taxonomy and relationships
