Transmission
Transmitted by a vector (2/2); a nematode
(1/1). Virus does not require a helper virus for vector transmission (1/1);
transmitted by mechanical inoculation; transmitted by grafting (2/2);
transmitted by contact between plants (1/1); not transmitted by seed (2/2).
Experimental host range
Many (>9) families susceptible
(1), or several (3-9) families susceptible (2), or few (<3) families
susceptible (1).

Physical and

Properties of particles in sap
TIP:
80-85.83-90 °C. LIV: 50-60.75-70 days. DEP: log10 minus 5 (2/3), or 6-7
(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 (1/3), or contains many virions (2/3).
Particle morphology
Virions isometric; not enveloped;
31-33.87-35 nm in diameter; rounded in profile (2), or angular in profile (2);
with a conspicuous capsomere arrangement (1/3), or without a conspicuous
capsomere arrangement (2/3).
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 126-132-135 S. Density
1.363-1.364-1.366 g cm-3 in CsCl. Isoelectric point pH 4.5.
A260/A280 ratio 1.64-1.72-1.8.
Biochemical properties
Virions contain 20-22.87-28 %
nucleic acid; 72-77.12-80 % protein; 0 % lipid.
Genome consists of RNA; single-stranded; linear (2/2). Total genome size
5.25-5.382-5.6 kb. Genome of two parts; largest (or only) genome part
3.75-3.882-4 kb; the 2nd largest 1.448-1.499-1.6 kb. Base composition 26 % G; 27
% A; 23 % C; 24 % U. 5´ terminus of RNA has a methylated nucleotide cap
(1/1). Infectivity retained when deproteinised with phenol or detergent (2/2).
Poly A region absent (1/1).
Features of the genome
Non-genomic nucleic acid
found in the virions (1/1). Sub-genomic mRNA found in infected cells
(1/1).
Features of proteins
Virion protein(s) one;
Mr 37000-38780-40800.
Virus-coded non-virion proteins identified by genomic sequence
analysis (1/1); three proteins found (1/1). Mr 99900. Mr of
2nd largest 37000. Mr of 3rd 34000.
Replication
Replication does not depend on a helper virus
(2/2).
Cytopathology
Virions found in cytoplasm (3/3), or in
nuclei (1/3). Inclusions present in infected cells (3), or absent from infected
cells (1); are amorphous X-bodies (1/3), or unusual in shape (2/3); they
contain virions (1/1).
Taxonomy and relationships
No data available.
