Isolate Description

Location: Japan.

Host of Isolate and Habitat Details
Source of isolate: Phalaris arundinacea.

Natural host and symptoms
Phalaris arundinacea — mosaic symptoms in leaves.

Classification

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

ICTVdB Virus Code: 00.057.0.81.012. Virus accession number: 57081012. Obsolete virus code: 57.0.1.T.012; superceded accession number: 5701t012.

Name, Synonyms and Lineage

ICTV approved acronym: CRMV. Virus is a tentative member of the genus 00.057.0.01. Potyvirus; family 00.057. Potyviridae .

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous and straight with a clear modal length with a length of 700-800 nm.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 50°C. The longevity in vitro (LIV) is 1 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

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

Lipids

Lipids are not reported.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Myzus persicae. Virus is transmitted in a non-persistent manner.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in few families. Susceptible host species are found in the Family Gramineae. The following species were susceptible to experimental virus infection: Lolium multiflorum, Phalaris arundinacea.

Diagnostic Hosts

Diagnostic host species and symptoms:

Lolium multiflorum, Phalaris arundinacea — mosaic leaf symptoms.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Lolium multiflorum, Phalaris arundinacea.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Lolium multiflorum (W), Phalaris arundinacea (W).

Geographical Distribution

The virus occurs in Japan.
