Abstract
A novel positive-sense single-stranded RNA virus was isolated from strain CCMJ1271 of the fungus Auricularia heimuer, and the complete genome sequence of the virus was determined. Database searching, sequence alignment, and phylogenetic analysis revealed that this fungal virus and some viruses of family Virgaviridae clustered into a single branch of a phylogenetic tree, and we thus tentatively named the virus "Auricularia heimuer mycovirgavirus 1" (AhMV1). The AhMV1 genome consists of 9,934 nucleotides and contains a short poly(A) tail and three open reading frames (ORFs). ORF1 encodes an RNA-dependent RNA polymerase (RdRp), ORF2 encodes a protein that is homologous to movement proteins of plant virgaviruses, and ORF3 encodes a coat protein (CP). AhMV1 is the first virus to be discovered in A. heimuer.
