Alphachrysovirus
Genus of viruses
From Wikipedia, the free encyclopedia
Alphachrysovirus is a genus of double-stranded RNA viruses. It is one of two genera in the family Chrysoviridae.[2] They infect fungi, in particular Penicillium. Their name is derived from the Greek word chrysos which means yellow-green. There are 20 species in this genus.[1][3][4]

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host.[1][3]
