Unknown, discovered using viral metagenomics. Presumably enveloped.
Segmented Negative-stranded RNA linear genome, RNA1 segment is about 7 kb, RNA2 segment about 4.7 kb Encodes for four 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 ORF2.
NUCLEAR or CYTOPLASMIC
