Genome organization and phylogenetic analysis of Heterobasidion ambi-like viruses 1–4 (HetAlV1–4). (A) Schematic presentation of HetAlV1–4 genomes with UTRs and predicted ORFs with translation initiation and termination sites. Green-colored ORFs represent the putative RdRPs. (B) Phylogenetic tree of the ambi-virus like viruses. The predicted aa sequences of putative RdRPs were aligned in MEGA X (Kumar et al., 2018) with MUSCLE and tree was constructed with the LG (+F) model with G+I rates among sites (best-fit model according to ModelFinder) and 500 bootstrap repetitions. All positions with less than 95% site coverage were eliminated, i.e., fewer than 5% alignment gaps, missing data, and ambiguous bases were allowed at any position. The Heterobasidion ambi-like viruses are designated with a star.
