Phylogenetic relationship of ‘Candidatus Nucleicultrix amoebiphila’ with the Alphaproteobacteria. (a) Maximum likelihood tree based on a concatenated 16S–23S rRNA alignment. ‘Candidatus Nucleicultrix amoebiphila’ (indicated by an asterisk) together with other protist symbionts forms a deeply branching lineage within the Alphaproteobacteria. (b) 16S rRNA-based maximum likelihood tree showing members of the protist symbiont clade containing ‘Candidatus Nucleicultrix amoebiphila’. Circles displayed at the nodes represent bootstrap values (upper half) and Bayesian posterior probability values (lower half), respectively. Black indicates support values >80% or probability values >0.8; gray indicates support values of 50–80% or probability values of 0.5–0.8, white indicates no support. Fully resolved trees are shown in Supplementary Figures S3–S5; accession numbers of sequences used for phylogenetic analyses are listed in Supplementary Table S1.
