A virus from Aspergillus cibarius with features of alpha- and betachrysoviruses

© 2023. The Author(s)..

From the ascomycete Aspergillus cibarius strain NW-FVA 2590, which was originally isolated from a root, associated with stem collar necrosis of Fraxinus excelsior L., a novel virus was isolated and characterized. Its genome is encoded on three monocistronic dsRNA segments ranging from 3683 bp (dsRNA 1) over 3093 (dsRNA 2) to 2902 bp (dsRNA 3), which are packed in isometric particles of around 35 nm. While the viral RdRp (P1) is encoded on segment 1, protein sequencing showed that two more structural proteins are present which are translated from dsRNA 2 (P2) and dsRNA 3 (P3) and possibly form the viral capsid. Additionally, P2 and P3 may undergo posttranslational modifications since the detected proteins bands deviated from the calculated sizes. Due to its phylogenetic position, the novel virus was grouped in the family of Chrysoviridae and was tentatively denominated as Aspergillus cibarius chrysovirus 1 (AcCV1). Due to its composition, biological properties and phylogenetic position, distant from the genera Alphachrysovirus and Betachrysovirus, we suggest to position AcCV1 in a proposed genus "Gammachrysovirus".
