Characterization of AfuRV1. (A) The RNA genome structure model for AfuRV1. The predicted ORFs are indicated by white boxes. The domains identified as methyl transferase, RdRP, and helicase are indicated in yellow, blue and brown boxes, respectively. Molecular phylogenetic analysis on the RdRp (B), methyltransferase (C), and helicase (D) domains was performed by maximum likelihood-based methodology. The numbers indicate the percentage bootstrap support from 1,000 RAxML bootstrap replicates. The best-fitting amino acid substitution models were [LG + F + G] (B) (C) and [rtREV + F + G] (D). The accession numbers and full virus names are listed in Table S4. The scale bar represents the number of substitutions per site. The viral sequences from fungi and invertebrates are indicated by orange circles or blue squares, respectively. AfuRV1 sequences are shown in red font.
