Prymnesiovirus

VIRION

Enveloped virion of which the membrane is surrounded by a capsid with an icosahedral symmetry (T=169), 100-170 nm in diameter. Dense material are present at each 5-fold symmetry vertex

GENOME

Linear, dsDNA genome of 120-485 kb with crosslinked hairpin ends.

GENE EXPRESSION

REPLICATION

NUCLEO-CYTOPLASMIC

  1. Virus attaches to host receptors , inducing release of viral genome into the cell.
  2. Migration of the DNA core to the nucleus?
  3. Synthesis of early proteins.
  4. Replication of genomic DNA..
  5. Late proteins synthesis, assembly of new virions in the cytoplasm
  6. Cell lysis and virion release in the extracellular space.
