The conserved sequence and secondary structure of the four candidate RNA motifs identified. (A) rhtB associated element, (B) pntA associated element, (C) bablM associated element, (D) SAR11_0636 element. See Additional files 8, 9, 10, 11 for alignments of all representatives. Structural notations are as in Fig. 2, and consensus nucleotides and covariation computed identically to Fig. 2.
