Magnoviridae

Magnoviridae is a proposed family of viruses in the order Herpesvirales. These viruses infect marine organisms, specifically tunicates, also known as sea squirts. The family name itself is derived from the Latin word "magnus" meaning large, referring to the relatively large size of the virions observed in electron microscopy. Magnoviridae are characterized by their double-stranded DNA genome enclosed within an icosahedral capsid, which is further enveloped by a lipid membrane. The replication cycle of these viruses is thought to be similar to other herpesviruses, involving entry into host cells, release of the viral genome, replication, assembly of new virions, and egress from the host cell. The ecological role of Magnoviridae within marine ecosystems is still under investigation, but they are believed to contribute to the natural mortality rates of tunicate populations. Research into Magnoviridae is ongoing to better understand their diversity, host interactions, and evolutionary relationships with other herpesviruses. Currently, Magnoviridae is a provisional classification, and further research is needed to definitively establish its taxonomic status.
