Concatenated multi-locus Poribacteria tree. Bolded names indicate sequences generated by the current study. Host abbreviations: Agelas tubulata, AG; Dysidea granulosa, DG; Melophlus sarasinorum, MS; Pseudoceratina sp., PC; Aplysina aerophoba, WGA MPMY, and MPMS. Tara Oceans genomes are italicized, with geographic abbreviations ARS, Arabian Sea; RS, Red Sea; MED Mediterranean Sea; NAT, North Atlantic; SAT, South Atlantic; NP, North Pacific; SP, South Pacific. Outgroup abbreviation RB_SH1 indicates Rhodopirellula baltica strain SH1. Asterisks highlight divisions supported by additional genomes in 16S rRNA trees (Supplementary Figure S2) and AAI distance clustering (Fig. 3). Supplementary Table S3 lists the 28 genes used to construct this tree, which were all present in all genomes shown
