Distribution of 2′-O-ribose methylation sites in archaeal 23S rRNA. Predicted sites of sRNA directed 2′-O-ribose methylation (Additional Files 1 and 3) from seven archaeal species (listed in Table 1) were mapped onto the consensus secondary structure of the archaeal 23S rRNA [21]. The multiple occurrences of methylation at a given nucleotide position is indicated by increasing dot size (i.e. methylation targets found in one to six organisms). The color of the dots (from blue to red) indicates increasing methylation frequency within a nine nucleotide window. The archaeal nucleotide alignment positions of sites of modification discussed in the context of 23S rRNA structure-function are indicated
