Partitiviridae (taxid:11012)

VIRION

Non-enveloped icosahedral capsid, about 35-40 nm in diameter with a T=2* icosahedral symmetry . The two genomic segments are encapsidated separately.

GENOME

Segmented linear dsRNA genome: 2 segments encoding potentially for 2 proteins. Segments are about 1.4-3.0 kb each, total size about 4 kb

GENE EXPRESSION

Each genomic segment is monocistronic.

ENZYMES

RNA-dependent RNA polymerase [RdRp]

REPLICATION

CYTOPLASMIC

Virus penetrates into the cytoplasm.
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.
(+)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.
Mature are transmitted to new cell by cytoplasmic exchange, sporogenesis or Hyphal anastomosis.
