Alphabaculovirus is a genus of viruses, in the family Baculoviridae. Winged insects, arthropods, lepidoptora, hymenoptera, diptera, and decapoda serve as natural hosts. There are currently 32 species in this genus including the type species Autographa californica multiple nucleopolyhedrovirus.
Group: dsDNA
Viruses in Alphabaculovirus are enveloped. Genomes are circular, around 80-180kb in length. The genome codes for 100 to 180 proteins.
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. Translation takes place by leaky scanning. 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. Winged insects, arthropods, lepidoptora, hymenoptera, diptera, and decapoda serve as the natural host. Transmission routes are fecal-oral.
