Unknown, discovered using viral metagenomics. Presumably non enveloped.
Segmented Negative-stranded RNA linear genome, RNA1 segment is about 6.5kb, RNA2 segment about 1.3kb 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
