Ampullaviridae

VIRION

image

Enveloped, bottle-shaped, with the pointed end likely involved in adsorption and channeling of viral DNA into the host cell.

GENOME

Monopartite, linear dsDNA genome of 23,9 kb, encoding for 56 ORFs.

GENE EXPRESSION

Genome is probably transcribed by host RNA polymerase.

REPLICATION

CYTOPLASMIC

  1. Virus attaches to host cell, and genomic DNA penetrates into the cytoplasm.
  2. Transcription of viral genes, possibly by a host RNA polymerase.
  3. Genome replication.
  4. Assembly and release of virions.
