In this study, we determined the TfoY regulon of V. cholerae using RNA-seq to better uderstand the protein's function. Overall design: mRNA profiles of a WT V. cholerae O1 El Tor strain (A1552) and of a TfoY-producing derivative of the WT strain (A1552-TntfoY). 3 independent biological replicates are provided for each bacterial strain. The bacteria were grown to high cell density and in the presence of arabinose (to induce TfoY in strain A1552-TntfoY).
