Computational prediction of small regulatory RNAs in A. pleuropneumoniae. (A) The sRNA candidates were defined as those predicted by at least two out of four (BLAST/Rfam, SIPHT, Infernal, and RNAz) algorithms with different approaches. As shown by the Venn diagram's intersections, the number of final candidates selected adopting this criterion was 23. (B) A CRISPR locus was also searched by using the software CRISPRFinder. For the A. pleuropneumoniae reference strain L20, a total of 26 direct repeats, separated by 25 spacers (gray) and surrounded by CRISPR-associated genes (arrows), were found.
