Curvulaviridae (taxid:2842317)

VIRION

Possibly non-enveloped icosahedral capsid.

GENOME

Segmented linear dsRNA genome: 2 segments encoding potentially for 3 proteins.

GENE EXPRESSION

Each genomic segment is monocistronic.

ENZYMES

• RNA-dependent RNA polymerase [RdRp]

REPLICATION

CYTOPLASMIC

1. Virus penetrates into the cytoplasm.
2. Transcription of the dsRNA genome by viral polymerase occurs inside the virion, so that dsRNA is never exposed to the cytoplasm. This plus-strand transcript is used as template for translation.
3. (+)RNAs are encapsidated in virion particle, inside which they are transcribed to give RNA (-) molecules with which they become base-paired to produce dsRNA genomes.
4. Mature are transmitted to new cell by cytoplasmic exchange, sporogenesis or Hyphal anastomosis.
