Tenuivirus ls a name of genera of plant virus

Plant virus

Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses are pathogenic to higher plants...

es. The type member is "Rice Stripe Virus." Other members of this genera include "Maize Stripe Virus," "Rice Hoja Blanca Virus'," and "Iranian Wheat Strip Virus." These plant viruses cause diseases in their host plants. Typical symptoms are chlorotic stripes on the affected leaves.

Virology

The virion particle consists of nucleocapsids that exhibit helical symmetry. The nucleocapsids are segmented and consist of either four or five species of single stranded RNA

RNA

Ribonucleic acid , or RNA, is one of the three major macromolecules that are essential for all known forms of life....

 and the N-protein. These viruses are transmitted by an arthropod

Arthropod

An arthropod is an invertebrate animal having an exoskeleton , a segmented body, and jointed appendages. Arthropods are members of the phylum Arthropoda , and include the insects, arachnids, crustaceans, and others...

 vectors in the families Cicadellidae or Delphacidae

Delphacidae

Delphacidae is a family of planthoppers containing about 2000 species, distributed worldwide. Delphacids are separated from other "hoppers" by the prominent spur on the tibia of the hindleg. All species are phytophagous, many occurring on various grasses, and some are important vectors for cereal...

.

Tenuivirus genome is segmented and has an ambisense coding strategy.

Taxonomy

Tenuivirus has close phylogenic relationship with members of the genus Tospovirus

Tospovirus

The Tospoviruses are a genus of negative RNA virus found within the family Bunyaviridae. They are the sole group of plant infecting viruses in this family, as all other described members of the Bunyaviridae infect animals. The genus takes its name from the discovery of Tomato spotted wilt virus ...

, the virions of which are bounded with an envelope

Viral envelope

Many viruses have viral envelopes covering their protein capsids. The envelopes typically are derived from portions of the host cell membranes , but include some viral glycoproteins. Functionally, viral envelopes are used to help viruses enter host cells...

. Tenuivirus encodes a membrane

Biological membrane

A biological membrane or biomembrane is an enclosing or separatingmembrane that acts as a selective barrier, within or around a cell. It consists of a lipid bilayer with embedded proteins that may constitute close to 50% of membrane content...

 protein

Protein

Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

precursor that is homologue to the virion envelope protein of Tospoviridae, although no envelope was found to associate with Tenuivirus virion.
