We have characterized a new mycovirus, Botrytis cinerea negative-stranded RNA virus 1.
BcNSRV-1 is close to plant emaraviruses and tospoviruses.
BcNSRV-1 is close to invertebrates-vertebrates hantaviruses and orthobunyaviruses.
BcNSRV-1 could derive from an invertebrate and vertebrate-infecting virus.
This finding will enhance our understanding the evolution of (-)RNA mycoviruses.
