Classification

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

ICTVdB Virus Code: 00.039.0.61.008. Virus accession number: 39061008. Obsolete virus code: 39.0.1.T.008; superceded accession number: 3901t008.

Name, Synonyms and Lineage

ICTV approved acronym: MRLV. Virus has not been assigned to a particular genus. Virus is of the genus 00.039.0.01. Luteovirus in the family 00.039. Luteoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The capsid.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA.

Proteins

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

Lipids

Lipids are absent.

Antigenicity

Possibly a strain of barley yellow dwarf virus (Waterhouse et al., 1988).

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Rhopalosiphum maidis, Macrosiphum (Sitobion) avenae and Schizaphis graminum. Virus is transmitted in a persistent manner.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Gramineae. The following species were susceptible to experimental virus infection: Setaria italica.

Geographical Distribution

The virus is found, but with no evidence of proliferation, in the Peoples Republic of China (Yu et al., 1957; 1958).
