CbsR16 is lowly transcribed, with some ambiguous reads mapping to it. a Artemis view of reads mapping to the CbsR16 locus (RSA 439 genome). The x-axis shows the location (bp) on the chromosome and the y-axis indicates coverage of reads mapping to that location. Reads above the y-axis indicate antisense reads, whereas reads below the y-axis indicate sense reads mapping to that genomic location. Blue lines signify ambiguous reads mapping to this locus, while red lines signify unambiguous reads. b mFold prediction of the CbsR16 sRNA secondary structure (∆G = − 85.24 kcal/mol). Red, blue, and green lines forming stem structures indicate G-C, A-U, and G-U base-pairing, respectively
