Classification

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

ICTVdB Virus Code: 00.078.0.81.009.00.001. Virus accession number: 78081109.

Name, Synonyms and Lineage

ICTV approved acronym: SuCV. Virus is assigned to species 00.078.0.81.009. Sunflower crinkle virus 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.

Proteins

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

Lipids

Lipids are present and located in the vesicles encapsidating the viral nucleic acid.

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 ASTERIDAE; Order Asterales;
Family Asteraceae (~Compositae) . Virus found in Helianthus annuus (common sunflower) [TaxID 4232].

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include deformation and chlorosis. Symptoms in leaves include development of patterns or markings that are visible in the intercostal regions. Intercostal regions show malformation. Leaf surface can be crinkled.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Compositae. The following species were susceptible to experimental virus infection: Helianthus annuus.

Geographical Distribution

The virus occurs in Kenya and Tanzania.
