FIG 7.

Phylogeny of the Durnavirales. Sequences in gray denote unclassified viruses, while those in bold refer to microalgal-associated viruses. Host lineages are indicated with circles to the right of major viral clades and correspond to metazoa, fungi, land plants, protozoa, and microalgae. The new viral sequences identified in this study are indicated with circles. The tree is mid-point rooted, and confident nodes (with SH-alrt likelihood ratio test values ≥80%) are represented as circles. The bar represents the number of amino acid substitutions per site.
