Prymnesiovirus is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There is currently only one species in this genus: the type species Chrysochromulina brevifilum virus PW1.
Group: dsDNA
Viruses in Prymnesiovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 100-170 nm. Genomes are linear, around 120-485kb in length.
Viral replication is nucleo-cytoplasmic. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. The virus exits the host cell by lysis via lytic phospholipids. Alga serve as the natural host. Transmission routes are passive diffusion.
