Visualization of RNA in live cells is a challenging task due to the transient character of most RNA molecules and the lack of adequate methods to label RNA noninvasively. Here, we describe a system for regulated RNA synthesis and visualization of RNA in live Escherichia coli cells based on protein complementation. This method allows for labeling RNA with a relatively small protein complex that becomes fluorescent only when bound to an RNA. This method greatly reduces the high fluorescence background characteristic of methods employing intact fluorescent proteins. A short reporter RNA was shown to localize at the cell periphery in nonrandom patterns.
