Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are spherical to pleomorphic measuring 80-100 nm in diameter. The envelope surrounds three nucleocapsids. Surface projections are distinctive spikes that are surrounded by a prominent fringe. Surface projections are embedded in a lipid bilayer that is 5 nm thick. Surface projections are 5-10 nm long. Capsid/nucleocapsid is elongated and exhibits helical symmetry. The ribonucleocapsid is filamentous with a length of 200-3000 nm (depending on arrangement) and a width of 2-2.5 nm. Nucleocapsids are circular.

Nucleic Acid

The Mr of the genome constitutes 1-2% of the virion by weight. The genome is segmented and consists of three segments of circular, negative-sense and ambisense (RNA-L), or ambisense (RNA-S and RNA-M) single-stranded RNA that forms a non-covalently closed circle. The complete genome is 16600 nucleotides long. Sequence can be accessed from EBI-EMBL, GenBank, and Rothamsted; the RNA-L is fully sequenced, complete sequence is 8897 nucleotides long. Sequence has the accession number [D10066]. RNA-M is fully or partially sequenced. Complete sequence is 4821 nucleotides long and sequenced region is 1120 nucleotides long has the accession number
[S48091];
[S58512] Em(40)_vi:S58512 Gb(84)_vi:S58512 33.6 kda protein, 11/93 1,1

.

RNA-S is fully or partially sequenced. Complete sequence is 2916 nucleotides long and sequenced region is 777 nucleotides long and encodes N gene, nucleoprotein has the accession number
[D00645]
[D00821] Em(40)_vi:TSWSNS, 5/92 2,837bp
[D13926] Em(40)_vi:TSWSNS1 Gb(84)_vi:TSWSNS, 2/93 2,837bp.
[X61799] Em(40)_vi:TSWVN Gb(84)_vi:TSWVN N mRNA for Nucleocapsid (N) protein. 10/91 777bp.
[Z36882] Em(43)_vi:Tswvng Gb(89)_vi:Tswvng (Italy) N gene. 8/94 777bp. The genome has terminally redundant sequences. The terminally redundant sequences have reiterated terminal sequences. The genome sequence is repeated at both ends. Terminal nucleotides are base-paired, forming non-covalently closed, circular RNAs. Nucleotide sequences at the 3'-terminus are complementary to the 5' end and form a panhandle. The 5'-terminal sequence has conserved regions and repeats complementary to the 3'-terminus; terminal repeats at the 5'-end are 8 nucleotides long; at the 5'-end AGAGCAAU... The 3'-terminus has conserved nucleotide sequences; of 8 nucleotides in length; at the 3' end UCUCGUUA.... The multipartite genome is found in one type of particle only.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about over 50% of the particle weight.

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 4 structural protein(s).

Lipids

Lipids are present and located in the envelope. Virions are composed of 20-30% lipids by weight. The composition of viral lipids and host cell membranes are similar. The lipids are of host origin and are derived from plasma membranes. Viral membranes include phospholipids, sterols, fatty acids, and glycolipids.

Release: The outer envelope lipids are derived from cellular Golgi membranes, or cell surface membranes (occasionally).
