  • Title: A novel mycovirus isolated from the plant-pathogenic fungus Alternaria dianthicola.
    Author: Hu Z, Guo J, Da Gao B, Zhong J.
    Journal: Arch Virol; 2020 Sep; 165(9):2105-2109. PubMed ID: 32556598.
    Abstract:
    Here, we describe the molecular characterization of a novel mycovirus isolated from a phytopathogenic fungus, Alternaria dianthicola, which we have named "Alternaria dianthicola dsRNA virus 1" (AdRV1). AdRV1 has a genome of 3,014 bp that contains two non-overlapping open reading frames (ORF1 and 2) coding for a hypothetical protein and an RNA-dependent RNA polymerase (RdRp), respectively. Based on the RdRp, AdRV1 is phylogenetically related to some unclassified dsRNA mycoviruses, including Alternaria longipes dsRNA virus 1, and shows a distant relationship to members of the family Partitiviridae. To the best of our knowledge, this is the first report of mycovirus infecting A. dianthicola.
