symptoms
Natural host range and symptoms
Symptoms
persist (18/20), or vary seasonally (2/20), or disappear soon after infection
(1/20).
Transmission
Transmitted by a vector (19/19); an insect
(18/19), or a mite (1/19); Aphididae (7/17), or Cicadellidae (4/17), or
Delphacidae (6/17). Transmitted in a persistent manner (13/13). Virus retained
when the vector moults (7/8), or lost by the vector when it moults (1/8);
multiplies in the vector (8/8); transmitted congenitally to the progeny of the
vector (2/6), or not transmitted congenitally to the progeny of the vector
(4/6); transmitted by mechanical inoculation (10/25), or not transmitted by
mechanical inoculation (15/25); transmitted by grafting (11/11); transmitted by
contact between plants (1/10), or not transmitted by contact between plants
(9/10); not transmitted by seed (14/14); transmitted by pollen to the seed
(1/7), or not transmitted by pollen (6/7).
Experimental host range
Several (3-9) families
susceptible (2/24), or few (<3) families susceptible (22/24).

Physical and
biochemical properties
Properties of particles in sap
TIP:
40-54-75 °C. LIV: 0.12-7.564-44 days. DEP: log10 minus 2 (1/8), or 3 (5/8),
or 4 (4/8), or 5 (3/8). Infectivity of sap decreased by treatment with
di-ethyl ether (3/3). Leaf sap contains few virions (10/15), or contains many
virions (5/15).
Particle morphology
Virions bacilliform (1/37), or
rhabdo- or bullet-shaped (37/37); enveloped (24/24); usually straight
(9/9); with a clear modal length (28/28); of 95-243.2-500 nm; 43-77.67-100 nm
wide. Axial canal obvious (13/18), or obscure (5/18); 4.5-17.25-30 nm in
diameter. Basic helix obvious (10/13), or obscure (3/13); pitch of basic helix
4-4.437-5 nm.
Physical properties
One sedimenting component in purified
preparations (7/8), or two sedimenting components in purified preparations
(2/8); sedimentation coefficient 774-922.1-1044 S. Density
1.165-1.181-1.2 g cm-3 in sucrose.
Biochemical properties
Virions contain 1-2.25-5 % nucleic
acid; 68-76.5-80 % protein; 15-20.37-25 % lipid.
Genome consists of RNA (5/5); single-stranded (5/5); linear (4/4). Total
genome size 7-11.84-14 kb. Genome unipartite (5/5); largest (or only) genome
part 7-11.84-14 kb. Base composition 26.4 % G; 21.3 % A; 22.5 % C; 29.8 % U.
Infectivity lost when deproteinised with proteases (4/4); lost when
deproteinised with phenol or detergent (4/4). Poly A region absent (2/2).
Additional factor required for infectivity (2/2). Genome has no
tRNA-like activity (1/1).
Features of the genome
Non-genomic nucleic acid
not found in the virions (2/2). Sub-genomic mRNA found in infected
cells (1/2), or not found in infected cells (1/2).
Features of proteins
Virion protein(s) four (4/11),
or five (6/11), or six (1/11); Mr 200-118000-240900. Mr of
2nd largest 78-62440-92000. Mr of 3rd largest 56-45380-61000.
Mr of 4th largest 31-25670-45000. Mr of 5th largest
37-23820-33000. Virion proteins glycosylated (7/7).
Replication
Genome replicates in nuclei (4/4), or in
cytoplasm (1/4). Replication does not depend on a helper virus (8/8).
Cytopathology
Virions found in cytoplasm (13/36), or in
nuclei (12/36), or in nucleoli (1/36), or in the perinuclear space (31/36), or
in mitochondria (2/36), or in unusual sites (1/36). Inclusions present in
infected cells (6/12), or absent from infected cells (6/12); are crystals in the
nucleus (1/7), or membranous bodies (1/7), or viroplasms (4/7), or unusual in
shape (3/7); they contain virions (5/6), or they do not contain virions (1/6).
