Complete genome sequence of a novel chrysovirus infecting Aspergillus terreus

AbstractA double-stranded RNA (dsRNA) mycovirus was obtained fromAspergillus terreus strain HJ3-26 and designated"Aspergillus terreus chrysovirus 1" (AtCV1). It consists of four dsRNA segments (dsRNA1-4) with lengths of 3612 bp, 3132 bp, 3153 bp, and 3144 bp, respectively. Sequence analysis showed that dsRNA1 encodes an RNA-dependent RNA polymerase (RdRp), dsRNA2 encodes a capsid protein, and both dsRNA3 and dsRNA4 encode hypothetical proteins. Phylogenetic analysis of the RdRp suggested that AtCV1 is a member of a new species of the genusAlphachrysovirus in the familyChrysoviridae. This is the first chrysovirus obtained fromA. terreus.
