Hydriviridae

VIRION

Undocumented: virus known by metagenomics. Possibly lemon shaped with a cork on one side.

GENOME

Circular, dsDNA genome of about 1,600 kb.

GENE EXPRESSION

Undocumented

REPLICATION

1. Virion binds to host cell with the protruding cork, and enters into host cell by phagocytosis
2. Fusion of viral envelope with cellular membrane, inducing the release of viral DNA into host cytoplasm.
3. Undocumented location of active genome: cytoplasm or nucleus?
4. Synthesis of early proteins.
5. Replication of genomic DNA.
6. Late proteins synthesis, assembly of new virions in the cytoplasmic factories
7. Cell lysis and virion release in the extracellular space.
