Phaeovirus

Phaeovirus is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There are nine species in this genus.

Taxonomy
The genus contains the following species:
 * Ectocarpus fasciculatus virus a
 * Ectocarpus siliculosus virus 1
 * Ectocarpus siliculosus virus a
 * Feldmannia irregularis virus a
 * Feldmannia species virus
 * Feldmannia species virus a
 * Hincksia hinckiae virus a
 * Myriotrichia clavaeformis virus a
 * Pilayella littoralis virus 1

Structure
Viruses in Phaeovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 120-150 nm. Genomes are linear, around 150-350kb in length.

Life cycle
Viral replication is nucleo-cytoplasmic, and is lysogenic. 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.
