During transcription initiation in vitro, RNA polymerase can engage in abortive initiation–the synthesis and release of short, 2 to 15 nucleotide, RNA transcripts–prior to productive initiation. It has not been known whether abortive initiation occurs in vivo. Using hybridization with locked nucleic acid probes, we directly detect abortive transcripts in vivo and thereby show that abortive initiation occurs in vivo. We further show that abortive initiation in vivo is a determinant of promoter strength, a determinant of RNA polymerase function, and a target of regulation by transcription factor GreA. Abortive transcripts may have functional, physiologically important roles in regulating gene expression in vivo.
