Rice Stripe Tenuivirus
''Rice stripe tenuivirus'' is an RNA plant pathogen of the genus ''Tenuivirus''.Xiong (2008) It is prevalent in Japan, China, and Korea and can infect plants of the family Poaceae, which include wheat and corn (see maize stripe virus).Wei (2009) Damage from this disease causes major reductions in rice crop yield every year. It is spread primarily by ''Laodelphax'' ''striatellus'', a small planthopper that feeds and damages rice plants by sap-sucking.Zhang (2010) Three other planthopper insects that transmit rice stripe virus include ''Unkanodes sapporona'', ''Unkanodoes albifascia'', and ''Terthron albovittatum''. The virus propagates in the planthopper and is passed down to 90% of a female's eggs.Gingery (1983) However, mechanically transmitting the virus by injecting sap from an affected plant to a healthy plant has not been widely successful. Symptoms Rice plants are susceptible to infection starting at the seedling age. The only known means of virus transmission is via plantho ...

Tenuivirus
''Tenuivirus'' is a plant virus genus belonging to ''Phenuiviridae'' family in the order ''Bunyavirales''. These plant viruses cause diseases in their host plants. Typical symptoms are chlorotic stripes on the affected leaves. This group of viruses make viral inclusions in infected cells which can be used to diagnose infection. Virology The virion particle consists of non-enveloped nucleocapsids that exhibit helical symmetry, forming thin, filamentous structures between 500–2100 nm long. The genomes are segmented and consist of four to six strands of negative-sense 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. Diseases Maize stripe disease, thought to be caused by Maize stripe virus, is a disease of Maize that is characterized by leaf blight and stunting of the plant.
