The targets of small regulatory RNAs can be mapped using High‐throughput Global sRNA target Identifi cation by Ligation and Sequencing (Hi‐GRIL‐seq). The position on the x and y axes identifies the genome coordinates of the interacting RNAs. Highlighted chimeras include those containing either the prrF1/2 sRNAs (blue) or the oprD (red) or pagL (green) mRNAs. For details, see the article by Zhang et al . on pp. 919–937 of this issue.
