Classification

This is a description of a plant virus at the strain/isolate level.

ICTVdB Virus Code: 00.078.0.01.007.00.001. Virus accession number: 78001107. NCBI Taxonomy ID: 193120.

Name, Synonyms and Lineage

ICTV approved acronym: PEMV-2. Virus is assigned to the species 00.078.0.01.007. Pea enation virus-2 and the genus 00.078.0.01. Umbravirus, but 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, but nucleic acid is not encapsidated and virus relies on the coat protein (CP) of a helper virus, characteristically from a virus in the family Luteoviridae, for encapisdation and for transmission by the vector of the helper virus.

Morphology

Virions have no true particles and consist of a nucleoprotein complex. During their life cycle, virions have not been observed outside a cellular environment. Virus nucleoprotein complex is found in membranous vesicles (?).

Nucleic Acid

Genome consists of one segment of linear positive-sense single-stranded RNA. Satellite RNA is also present. The genome has been fully sequenced and the complete genome is 4253 nulclotides long. the genomic RNA sequences has the accession number [U03563] (clone pPER2d), is 4253 nucleotides long and is encoding the viral replicase gene. The satellite RNA has the accession number [U03564] of strain WSG and is 717 nucleotides long. GenBank records for nucleotide sequence(s): nucleotide sequences and for complete genome sequences.

Proteins

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

Biological Properties

Natural Host Range

Viral hosts belong to the Domain Eucarya.

Domain Eucarya Kingdom Plantae.

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

Class Magnoliopsida (Dicotyledonae) Subclass ROSIDAE; Order Fabales;
Family Fabaceae (~Leguminosae-Papilionoideae) Pisum sativum.

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).
