<p>Phylogeny of the <i>Sodiomyces</i> sp. based on the ITS rDNA sequences (A), with the origin location of dsRNA-containing strains and phylogeny of the SaFV1 isolates based on the whole genome sequence (B).</p

Presence of SMC domain in members of putative Fusariviridae family.

<p>Position of the SMC domain on the ORF2 and E-value is presented.</p

<i>S</i>. <i>alkalinus</i> isolates growing on alkaline agar plate.

<p>Five days old isolates of <i>S</i>. <i>alkalinus</i> did not form inhibition zones or barrages between the strains although the mycelia did not fuse with each other.</p

The genomic organization of SaFV1 compared to other viruses that possess structural maintenance of chromosomes domain.

<p>Boxes and lines represent open reading frames (ORFs) and non-coding sequences, respectively. Positions of polymerase (Pol, red), helicase (Hel, green), and structural maintenance of chromosomes (SMC, blue) domains are indicated. VP1-4 are structural proteins. Genomes are shown to scale.</p

Phylogenetic tree of selected members of prokaryotic, eukaryotic, and viral SMC domains.

Potential secondary structures of 3´end, and ORF1-ORF2 intergenic region of Sodiomyces alkalinus fusarivirus 1 (SaFV1).

<p>a) Potential secondary structures of 3´end (from 6183–6239 nucleotides) and b) ORF1-ORF2 intergenic region (from 4590 to 4659 nucleotides). The ΔG values (kcal/mol) were calculated using RNAfold program. UAA stop codons and AUG codon are marked.</p

Phylogenetic tree as inferred from the I-VII RdRp motifs of fusariviruses.

<p>Maximum likelihood tree generated using RdRp segments of motifs I to VII with 1000 bootstrap replicates. Plum pox virus was used as an outgroup. Presence of the SMC domain in ORF2 protein of fusariviruses is indicated with an asterisk. Bootstrap values above 50% are given next to the branches. Section marks (§) indicate proposed taxa.</p
