Biology:Raphidovirus

From HandWiki

Raphidovirus (likely misspelled Rhaphidovirus) is a genus of viruses, in the family Phycodnaviridae. Alga serve as natural hosts. There is only one species in this genus: Heterosigma akashiwo virus 01 (HaV01, Raphidovirus japonicum).[1][2][3]

Structure

Schematic drawing of a typical Phycodnaviridae virion (cross section and side view)

Viruses in Raphidovirus are enveloped, with icosahedral and round geometries, and T=169 symmetry. The diameter is around 100-220 nm. Genomes are linear, around 295kb in length.[1]

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.[1]
