Taxonomy
Group: dsDNA
Structure
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.
Life Cycle
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.
