The FNR regulon in “Ca. Accumulibacter phosphatis.” (A) Motif diagram showing a putative FNR-binding site identified upstream of respiratory genes. (B) Distribution of KEGG functional categories in the fraction of genes with the FNR motif in genomes of “Ca. Accumulibacter phosphatis.” (C) The predicted conservation of the FNR regulon determined in the “Ca. Accumulibacter phosphatis” lineage; only genes with motifs present in at least 4 genomes are shown. Black indicates that the corresponding strain does not possess the corresponding gene; blue indicates that the strain possesses the gene but that an FNR motif was not found within the upstream intergenic region. Yellow indicates that the gene with an FNR motif is present in the genome.
