Boscovirus (taxid:2842563)

VIRION

Unknown, discovered using viral metagenomics. Presumably not enveloped.

GENOME

image

Segmented Negative-stranded RNA linear genome, RNA1 segment is about 6.5kb, RNA2 segment about 2.4kb Encodes for two proteins.

GENE EXPRESSION

Viral RNA-dependent RNA polymerase (L) binds to a promoter on each segment and transcribes a messenger RNA. Genomic RNA is possibly encapsidated by N protein.

ENZYMES

REPLICATION

NUCLEAR or CYTOPLASMIC

  1. Virus invades host cells by unknown mechanism: genomic genome is released in cytoplasm.
  2. Transcription
  3. Replication
  4. Unknown mechanism of propagation.
