Sclerodarnavirus
Genus of viruses
From Wikipedia, the free encyclopedia
Sclerodarnavirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. Fungi serve as natural hosts. There is only one species in this genus: Sclerotinia sclerotiorum debilitation-associated RNA virus (Sclerodarnavirus sclerotiniae). Diseases associated with this genus include: hypovirulence or debilitation.[1][2][3]

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tripartite non-tubule guided viral movement. Fungi serve as the natural host.[1]
