Unknown, discovered using viral metagenomics. Presumably not enveloped.
Segmented Negative-stranded RNA linear genome, RNA1 segment is about 6.5kb, RNA2 segment about 2.4kb Encodes for two proteins.
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.
NUCLEAR or CYTOPLASMIC
- Virus invades host cells by unknown mechanism: genomic genome is released in cytoplasm.
- Unknown mechanism of propagation.
