First report of a chrysovirus infecting a member of the fungal genus Ilyonectria.

ABSTRACT: The fungus Ilyonectria pseudodestructans belongs to the family Nectriaceae and was found to be part of the endophytic microbiome of apple trees (Malus x domestica, Borkh.) with apple replant disease (ARD). After dsRNA extraction, a mycoviral infection became evident. Here, we report the identification of a new virus, tentatively named "Ilyonectria pseudodestructans chrysovirus 1" (IpCV1), as the first member of the proposed new species "Alphachrysovirus ilyonectriae" within the genus Alphachrysovirus. This is the first report of a chrysovirus infecting a member of the fungal genus Ilyonectria. IpCV1 has a tripartite dsRNA genome with a total length of 8944 bp. The segments are 3439 bp, 2850 bp, and 2655 bp in length, and each dsRNA carries a single ORF. The encoded viral proteins are a 125
