Gammabaculovirus

Gammabaculovirus is a genus of viruses, in the family Baculoviridae. Hymenoptera serve as natural hosts. There are currently only two species in this genus including the type species Neodiprion lecontei nucleopolyhedrovirus.[1][2][3]

Structure

Viruses in Gammabaculovirus are enveloped. Genomes are circular, around 82-86kb in length. The genome codes for 90 proteins.[2][3]

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment of the viral glycoproteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. Dna templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export, and existing in occlusion bodies after cell death and remaining infectious until finding another host. Hymenoptera serve as the natural host. Transmission routes are fecal-oral.[2][3]
