Order: Mononegavirales
Family: Rhabdoviridae
Genus: Nucleorhabdovirus
Type Species

Nucleorhabdovirus is a genus of viruses in the order Mononegavirales, in the family Rhabdoviridae. Planthoppers and plants serve as natural hosts. There are currently ten species in this genus including the type species Potato yellow dwarf virus.[1][2]

Structure

Viruses in Nucleorhabdovirus are enveloped, with bullet-shaped and bacilliform geometries. These viruses are about 75 nm wide and 180 nm long. Genomes are linear, around 11-15kb in length. The genome codes for 5 to 6 proteins.[1]

Life Cycle

Viral replication is nuclear. The virus is transmitted via a vector (insect). Transmission routes are vector and mechanical. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Planthopper and plants serve as the natural host. [1]
