Majority consensus maximum likelihood tree (250 bootstrap replicates) based on comparison of all analyzed protein markers, showing the relationships between the analyzed spounaviruses.

<p>Branch labels indicate their percent bootstrap support. Leaves are colored by proposed in-subfamily clustering: blue – Bastille group, green – Twort group, red – Bacillus phage SPO1. Abbreviations include name of host taxon (Ba – <i>Bacillus</i>, Bx – <i>Brochothrix</i>, En – <i>Enterococcus</i>, Lb – <i>Lactobacillus</i>, Li – <i>Listeria</i>, St – <i>Staphylococcus</i>) and the bacteriophage name. All analyzed sequences are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0086632#pone.0086632.s004" target="_blank">Table S1</a>.
