It's a quick review of sRNAs in H. pylori, a species once thought to use very little RNA-based regulation (AKA riboregulation). The presumed lack was based on observations that H. pylori lacks the RNA-binding protein Hfq, generally thought to be a requirement for riboregulation. Turns out that's not the case. H. pylori may regulate plenty of cellular activities using sRNA, including the stress response and flagellum biogenesis.
