Natural host and symptoms
Very many hosts (Kaper and Waterworth, 1981)
including:
Cucumis sativus and many other cucurbits — mosaics and
stunting, reduced fruit yield.
Lycopersicon esculentum — mosaic,
reduction of leaf laminae ("fernleaf") and stunting.
Spinacia oleracea
— severe chlorosis and stunting.

ICTV approved acronym: CMV. Virus is the type of the genus
00.010.0.04.
Cucumovirus in the family
00.010.
Bromoviridae.
Virions consist of a capsid. Virus capsid is not
enveloped, round with icosahedral
symmetry. The isometric capsid has a diameter of
about 29 nm. Capsids appear round. The capsomer arrangement is not obvious. The
capsid consists of 32 capsomers. Virus preparations contain more than one
particle component.
Capsids all have the same appearance.

Addtional electron micrograph of
Bromoviridae can be found in the Picture Gallery.
Electron microscopic preparation and references: Virus preparation
contains few virions, or many virions. Freeze-dry preparations for shadowing, or
fix with aldehyde for negative staining with PTA. Reference for electron
microscopic methods: Lot et al. (1972) and modified by Peden and Symons
in 1973 (Clark et al., 1974).

Capsid structures, detailed structural and computational analysis are found
in the Protein Data Bank (PDB) using VIPERdB, the VIrus Particle
ExploreR 1f15.
Virions have a buoyant density in CsCl of 1.367 g
cm-3 (after fixation with formaldehyde). There are 1 sedimenting
component(s) found in purified preparations. The sedimentation coefficient is 99
S20w. Isoelectric point pH is 5.5 (Q strain).
A260/A280 ratio is 1.7 (corrected). The thermal
inactivation point (TIP) is at 55-70°C. The longevity in vitro
(LIV) is 1-10 days. Although the titer is dependent on the host, the
decimal exponent (DEX) of the dilution end point is usually around 3-6. The
infectivity is not changed by treatment with ether; retained when deproteinized
with proteases, or decreased when deproteinized with proteases; retained when
deproteinized with phenol or detergent.
The Mr
of the genome constitutes 18% of the virion by weight. The genome is segmented,
tripartite (segements are distribute among 3 particle types of different size), and
consists of four segments of to five segments of linear
positive-sense, single-stranded RNA. Minor species of
non-genomic nucleic acid are also found in virions. The encapsidated
nucleic acid is mainly of genomic origin, but virions may also contain
subgenomic RNA and satellite RNA (in some isolates, virions may contain
mRNA derived from genomic RNA-3. The complete genome is
8621 nucleotides long. RNA-1 is fully sequenced and complete sequence is
3389 nucleotides long. Sequenced genome has the accession number(s)

RNA-4 is subgenomic has been
sequenced, but only an estimate is provided, complete sequence is 1000
nucleotides long. The genome has a base ratio of 24 % guanine; 23 % adenine; 23
% cytosine; 30 % uracil. Nucleotide sequences at the 3'-terminus are
similar. The 5'-end of the genome has a methylated nucleotide cap; cap sequence
type is m7G5'ppp5 (on all 4 RNAs). The 3'-terminus has conserved nucleotide
sequences; sequence has 200 nucleotides in length; in all RNA species
(characteristic for each taxon). The 3'-terminus has no poly (A) tract. The
3'-terminus has on all genomic RNAs a tRNA-like structure
that can be aminoacylated with tyrosine. The genome has no
intergenic poly (A) region. The multipartite genome is divided among more than
one type of particle and the segments are distributed between 3
different types of particles. The largest particles contain each one molecule of
RNA-1 (sedimenting component B). The medium sized particles contain each one
molecule of RNA-2 (sedimenting component M). The smallest particles contain one
molecule each of RNA-3 and RNA-4 (sedimenting component T). Reference to
nucleotide sequence Gould and Symons (1977).
GenBank records for
nucleotide sequences;
complete genome sequences.
Proteins
constitute about 82% of the particle weight.
The viral genome encodes structural proteins and non-structural proteins.
Virions consist of 1 structural protein(s) located in the capsid.
Structural Proteins: Capsid protein is involved in viral
encapsidation and involved in protein movement.
Reference to method of preparation: Habili and Francki (1974).
Reference to amino acid sequence or composition Davies and Symons
(1987, Mossop (1978).
Non-Structural Proteins: Virus-coded non-structural
proteins have been identified by sequence analysis (Clark et al.
(1974, Kumarasamy and Symons (1979, Gill et al. (1981)) and 3
non-structural protein(s) are found.
Lipids are
absent.
Genome Organization and Replication
Transcription: Sub-genomic RNA is
present in infected cells; a transcription of coat protein mRNA, which is
also the encapsidated RNA-4 of 1.027 kb; encoding the coat protein.
The virus is serologically
related to peanut stunt and tomato aspermy viruses, but distantly.
Sequence homologies indicate that the virus is distantly related to brome
mosaic virus, and also, in sequences in RNA-1 and RNA-2, to alfalfa mosaic and
tobacco mosaic viruses (Rezaian et al., 1985; Davies and Symons, 1987).

Virus is transmitted by a vector. Virus is transmitted by
mechanical inoculation; transmitted by seeds (in 19 species, but in variable
extents).
Vector Transmission:
Virus is transmitted by arthropods, by insects

Acyrthosiphon pisum, Aphis craccivora and Myzus persicae. Virus is
transmitted in a non-persistent manner.
