The first subcolumn in each column is the number of riboswitches, the second subcolumn is the normalized frequences of riboswitch occurrence (the number of riboswitches per 105 bp). Columns: α,β,γ,δ – classes of Proteobacteria, B/C – Bacteroidetes/Chlorobi, Cya – Cyanobacteria, Frm – Firmicutes, Act – Actinobacteria, Unk – unknown taxonomy.
