Isolate Description

Location: New York; the United States of America.

Host of Isolate and Habitat Details
Source of isolate: Vicia faba.

Reference to Isolation Report
Osborn (1935).

Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.078.0.01.007. Virus accession number: 78001007. Obsolete virus code: 24.0.1.0.001; superceded accession number: 24010001.
NCBI Taxon Identifier NCBI Taxonomy ID: 193120.

Name, Synonyms and Lineage

The taxon has the accepted ICTV name (Pea enation mosaic virus has been split into PEMV-1 Enamovirus and PEMV-2 Umbravirus).

Synonym(s): enation pea mosaic virus. ICTV approved acronym: PEMV-2. Acronym(s): PEMV. Virus is an ICTV approved species of the genus 00.078.0.01. Umbravirus; not assigned to a family.

Virion Properties

Enveloped structures occur in vacuoles of infected cells, but no conventional virus structure have been found. Particles contain nucleic acid. Virus relies for encapisadtion and transmittion on the vector of the helper virus and virus relies on the coat protein (CP) from a helper virus, characteristically from a virus in the family (Luteoviridae).

Virion Properties

Morphology

No true particles are found, but vesicles containing viral matter are recovered that consist of a nucleoprotein complex. During their life cycle, virions have not been observed outside a cellular environment.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA. Minor species of genomic nucleic acid are found in addition to the full length genome; there are 1 minor species found; non-genomic nucleic acid are also found in virions. The encapsidated nucleic acid is mainly of genomic origin, but virions may also contain satellite RNA; virions may contain one satellite nucleic acid species including satellite RNA. The complete genome is 4253 nucleotides long. The RNA is fully sequenced, complete sequence is 4253 nucleotides long and encodes viral replicase gene. Sequence has the accession number [U03563], and the NCBI reference genome has the accession number [NC_003853].

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes prehaps structural proteins and non-structural proteins, or structural proteins.

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include deformation and chlorosis; include deformation of leaves. Symptoms in leaves include change in texture and development of patterns or markings that are visible in the venation. Intercostal regions show malformation. Leaf surface can be warped. Leaves with mosaic.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Umbravirus at the meeting in San Diego, March 1998, to change the position of the taxon. The proposal has been approved at the meeting of the Executive Committee in San Diego, 1998, the taxon has been designated as Type Species (in the genus Umbravirus).
