GFP reporter assays validate Rra-RNA’s regulatory role. GFP reporter assays validate the regulatory capacity of Rra-RNA in response to Rra-S15. Rra-RNA structure and sequence are the same as described in Figure 4. All relative fluorescence values were calculated by normalizing GFP/OD600. All bars are 3+ independent experiments. *indicates p < 0.01; **indicates p < 0.001.
