Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.011.0.05.002. Virus accession number: 11005002. Obsolete virus code: 11.0.5.0.002; superceded accession number: 11050002.
NCBI Taxon Identifier NCBI Taxonomy ID: 11612.

Name, Synonyms and Lineage

ICTV approved acronym: INSV. Virus is an ICTV approved species of the genus 00.011.0.05. Tospovirus in the family 00.011. Bunyaviridae.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are spherical to pleomorphic. Surface projections are embedded in a lipid bilayer that is 5 nm thick. Capsid/nucleocapsid is elongated with helical symmetry. The ribonucleocapsid is filamentous and has a width of 2-2.5 nm. Nucleocapsids are circular.

Nucleic Acid

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 RNA-L. RNA-M is fully sequenced. Complete sequence is 4972 nucleotides long and has the accession number [M74904] Em(40)_vi:IMNGNSM Gb(84)_vi:IMNGNSM Impatiens necrotic spot virus G2-G1 polyprotein and nonstructural protein of the middle RNA. RNA-S is fully sequenced, complete sequence is 2992 nucleotides long and has the accession number
[X66972] Em(40)_vi:INSVNSP Gb(84)_vi:INSVNSP Impatiens necrotic spot virus gene for nucleocapsid and non-structural proteins. 11/93 2,992b 3 sequences
[D00914] Em(40)_vi:IMNNCG Gb(84)_vi:IMNNUCL Impatiens necrotic spot virus (INSV) S RNA, 3'-noncoding region and N gene. 11/92 1,144bp. 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. 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....

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are present and located in the envelope. 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).

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Class Magnoliopsida (Dicotyledonae)
Subclass ASTERIDAE; Order Scrophulariales.

Transmission and Vector Relationships

Virus is transmitted by a vector.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Thysanoptera; Frankliniella occidentalis.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Balsaminaceae. The following species were susceptible to experimental virus infection: Impatiens.

Geographical Distribution

The virus occurs in Belgium, Germany, the Netherlands, Poland, the United Kingdom, and the United States of America.
