Tenuivirus ls a name of genera of plant viruses. 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.
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 and the N-protein. These viruses are transmitted by an arthropod vectors in the families Cicadellidae or Delphacidae.
Tenuivirus genome is segmented and has an ambisense coding strategy.
Tenuivirus has close phylogenic relationship with members of the genus Tospovirus, the virions of which are bounded with an envelope. Tenuivirus encodes a membrane protein precursor that is homologue to the virion envelope protein of Tospoviridae, although no envelope was found to associate with Tenuivirus virion.
