Duamitovirus (taxid:2948686)

VIRION

image

No true virion, no structural proteins. Genomes are associated with their RdRp in the cytoplasm.

GENOME

image

Monopartite, linear, ssRNA(+) genome of of 2.5-2.9 kb. The RNA is not capped.

GENE EXPRESSION

The virion RNA is infectious and serves as both the genome and viral messenger RNA. The genome has one ORF encoding an RNA-dependent RNA polymerase.

ENZYMES

REPLICATION

CYTOPLASMIC

  1. Virus genome is transmitted horizontally through mating or vertically from mother to daughter cells.
  2. Translation of genomic RNA produces viral RdRp.
  3. A dsRNA genome is synthesized from the genomic ssRNA(+).
  4. The dsRNA genome is transcribed/replicated thereby providing viral mRNAs/new ssRNA(+) genomes.
