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: 00.077.0.01.015. Virus accession number: 77001015. Obsolete virus code: 77.0.1.0.011; superceded accession number: 77010011.
NCBI Taxon Identifier NCBI Taxonomy ID: 185692.

Name, Synonyms and Lineage

ICTV approved acronym: PFYMV (PaYMV). Virus is an ICTV approved species of the genus 00.077.0.01. Tymovirus; family 00.077. Tymoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 28 nm. Capsids appear round, or hexagonal in outline. The capsomer arrangement is not obvious.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Kitajima, adapted from Bozarth et al. (1977).

Physicochemical and Physical Properties

There are 2 sedimenting component(s) found in purified preparations. The sedimentation coefficient is of the fastest 125 S20w; of the other(s) are 62 S20w. The thermal inactivation point (TIP) is at 55-60°C. The longevity in vitro (LIV) is 8 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5. The infectivity is not changed by treatment with ether.

Nucleic Acid

The Mr of the genome constitutes 25% of the virion by weight (or less). The genome is monopartite. Only one particle size of linear, single-stranded RNA is recovered. The complete genome is 2000 nucleotides long, is sequenced and complete sequence is about 2000 nucleotides long. Reference to nucleotide sequence Aviv and Leder (1972).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s) located in the capsid.

Structural Proteins: Reference to method of preparation: Laemmli (1970).

Lipids

Lipids are not reported.

Translation: Coat protein mRNA is translated in the cytoplasm, possibly.

The genome replicates in perhaps in association with chloroplasts (in the peripheral vesicles).

Antigenicity

The virus is serologically related to Okra mosaic virus, Kennedya mosaic virus, Clitoria yellow mosaic virus, Cocoa yellow mosaic virus and Turnip yellow mosaic virus.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Class Magnoliopsida (Dicotyledonae)
Subclass DILLENIIDAE.

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include chlorosis and development of patterns or markings that are visible in the intercostal regions. Intercostal regions show chlorosis. Leaves are turning yellow. Leaves with mosaic have yellow mosaic.

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; transmitted by grafting; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Coleoptera; Diabrotica speciosa (experimental transmission). 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 Passifloraceae. The following species were susceptible to experimental virus infection: Passiflora edulis, Passiflora edulis f. flavicarpa.

Diagnostic Hosts

Diagnostic host species and symptoms:

Several Passiflora ssp., especially Passiflora edulis f. flavicarpa.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Passiflora edulis f. flavicarpa.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Passiflora edulis f. flavicarpa (W). No local lesion host.

References to host data: Crestani (1984).

Histopathology: Virus can be best detected in all parts of the host plant. Virions are found in the cytoplasm and cell vacuole.

Cytopathology: Inclusions are not present in infected cells. Other cellular changes include peripheral vesicles in the chloroplasts, which are characteristic for tymoviruses.

Geographical Distribution

The virus occurs in Brazil.
