Abstract

Escherichia coli serotype O157:H7 strain 20R2R is a derivative of clinical isolate PA20. Prophage excision from the coding region of a PA20 transcription factor restored RpoS-dependent biofilm formation in 20R2R, providing a model for O157:H7 stress adaptation when transitioning between clinical and environmental settings. We report here the complete 20R2R genome sequence.
