title: A bacterial pathogen flips the riboswitch.
abstract: Riboswitches are RNA structures traditionally viewed as acting in cis to regulate downstream gene expression in bacteria. In a recent issue of Cell, Loh and colleagues report on the ability of a riboswitch to act in trans to modulate the expression of a critical bacterial virulence regulator.
