symptoms
Natural host range and symptoms
Symptoms
persist (19/20), or vary seasonally (4/20), or disappear soon after infection
(2/20).
Transmission
Transmitted by a vector (25/26), or means
not involving a vector (1/26); an insect (25/25); Aphididae (25/25). Transmitted
in a persistent manner (25/25). Virus retained when the vector moults (14/14);
does not multiply in the vector (11/11); not transmitted congenitally to the
progeny of the vector (9/9); does not require a helper virus for vector
transmission (2/8), or can help the vector transmission of another virus (7/8);
not transmitted by mechanical inoculation (20/20); transmitted by grafting
(10/12), or not transmitted by grafting (2/12); not transmitted by contact
between plants (14/14); not transmitted by seed (16/16); not transmitted by
pollen (12/12).
Experimental host range
Many (>9) families susceptible
(1/23), or several (3-9) families susceptible (6/23), or few (<3) families
susceptible (16/23).

Physical and
biochemical properties
Properties of particles in sap
TIP:
45-63.12-80 °C. LIV: 5-13.5-16 days. DEP: log10 minus 2 (2/3), or 3-4 (1/3).
Infectivity of sap decreased by treatment with di-ethyl ether (1/2), or not
changed by treatment with di-ethyl ether (1/2). Leaf sap contains few virions
(13/13).
Particle morphology
Virions isometric (15/15); not
enveloped (13/13); 23-26.36-30 nm in diameter; rounded in profile (7/14), or
angular in profile (8/14); with a conspicuous capsomere arrangement (1/12), or
without a conspicuous capsomere arrangement (11/12).
Physical properties
One sedimenting component in purified
preparations (13/13); sedimentation coefficient 104-113.3-118 S. Density
1.38-1.4-1.42 g cm-3 in CsCl. Isoelectric point pH 5.3. A260/A280
ratio 1.8.
Biochemical properties
Virions contain 28-30.31-37.8 %
nucleic acid; 70-70.71-72 % protein; 0 % lipid.
Genome consists of RNA (11/11); single-stranded (11/11); linear (9/9).
Total genome size 5.641-5.968-6.9 kb. Genome unipartite (9/9); largest (or only)
genome part 5.6-6.044-6.9 kb. Base composition 24.6 % G; 29.6 % A; 23.8 % C; 22
% U. Infectivity retained when deproteinised with proteases (1/1); retained when
deproteinised with phenol or detergent (1/1). Poly A region absent (4/4).
Features of the genome
Non-genomic nucleic acid
found in the virions (4/4); is subgenomic mRNA (1/4), or satellite RNA
(2/4), or of an unusual type of structure (1/4). Sub-genomic mRNA
found in infected cells (1/1).
Features of proteins
Virion protein(s) one (6/10), or
two (3/10), or four (1/10); Mr 22600-31540-60000. Mr of 2nd
largest 7000-34000-55000. Mr of 3rd largest 40000. Mr of 4th
largest 25000. Virion proteins not glycosylated (1/1). Virion proteins not
phosphorylated (1/1).
Virus-coded non-virion proteins isolated (1/2), or identified by
genomic sequence analysis (1/2); three proteins found (1/2), or six proteins
found (1/2). Mr 95000-109900-124900. Mr of 2nd largest
69000-70000-71000. Mr of 3rd 29000-31500-34000. Mr of 4th
22000. Mr of 5th and smaller 6000.
Replication
Genome replicates in cytoplasm (1/1).
Replication does not depend on a helper virus (7/7).
Cytopathology
Virions found in cytoplasm (9/10), or in
nuclei (5/10), or in cell vacuoles (6/10). Inclusions present in infected cells
(3/9), or absent from infected cells (6/9); are crystals in the cytoplasm (2/3),
or amorphous X-bodies (1/3), or membranous bodies (1/3); they contain virions
(3/3).
Taxonomy and relationships
No data available.
