Complete genome sequence of a novel chrysovirus infecting Talaromyces neofusisporus
Archives of Virology(2022)
摘要
A double-stranded RNA (dsRNA) mycovirus was isolated from Talaromyces neofusisporus isolate HJ1-6 and named "Talaromyces neofusisporus chrysovirus 1" (TnCV1). It was found to consist of four dsRNA segments (TnCV1-1, TnCV1-2, TnCV1-3, and TnCV1-4) with lengths of 3595 bp, 3063 bp, 3054 bp, and 2876 bp, respectively. Sequence analysis showed that TnCV1-1 contains an open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp) of 1136 amino acids (aa), TnCV1-2 contains an ORF encoding a hypothetical protein of 906 aa, TnCV1-3 contains an ORF encoding a putative capsid protein (CP) of 938 aa, and TnCV1-4 contains an ORF encoding a hypothetical protein of 849 aa. The 5’ and 3’ untranslated regions (UTRs) of TnCV1-1, TnCV1-2, TnCV1-3, and TnCV1-4 showed a high degree of sequence similarity to each other. Phylogenetic analysis based on RdRp sequences suggested that TnCV1 is a new member of the genus Alphachrysovirus in the family Chrysoviridae. This is the first chrysovirus isolated from T. neofusisporus.
