Columns are as follows. "RNA?" : is this motif likely to represent a biological RNA? "Y" = certainly, "y" = probably, "?" = ambiguous, "n" = probably not, "N" = no. "cis-reg" : is the motif cis-regulatory? "switch?" : is the motif a riboswitch? Additional annotation and justification is in Additional File 2. "Taxa" : common taxon/taxa carrying this motif. Many motifs are discussed only in Additional file 1. "Rfam" : accession numbers of motifs that were submitted to the Rfam database for version 10.1. Note: consensus diagrams of some motifs were presented as supplementary data of a previous report [21] under simplified names: Acido-1 (previously ac-1), Dictyoglomi-1 (dct-1), Gut-1 (gt-1), manA (manA), Termite-flg (tf-1) and Whalefall-1 (wf-1).
