From: Transcriptional cross-activation between toxin-antitoxin systems of Escherichia coli
Transcription of TA operons in response to expression of RelE. Production of RelE was induced in cultures of BW25113 bearing plasmids pKP3035 and pKP3033. RNA extracted at timepoints −1 (before induction), 15, 60, and 120 min was subjected to northern analysis using oligoprobes complementary to the mRNAs of different toxins (underlined) and antitoxins. Panel A refers to the first and panel B to the second gene of the TA operon.
