Tristromaviridae

VIRION

Enveloped, rod-shaped virion about 410 nm long and 38 nm in diameter. Genomic DNA is packaged into a helical core.

GENOME

Linear dsDNA genome of 15.9 kb. Extremities of the DNA are modified in an unknown manner.

GENE EXPRESSION

The genome is organized in operons.

REPLICATION

CYTOPLASMIC

  1. Adsorption: the phage attaches to target cell
  2. Injection: viral DNA is injected in host cell cytoplasm
  3. Transcription and translation of early genes
  4. Replication of genomic DNA
  5. Transcription and translation of late genes
  6. Genomic DNA is packaged in new virions
  7. Mature virions are released from the cell
