Significance All organisms sense and respond to their environments. One way bacteria interact with their surroundings is by dynamically extending and retracting filamentous appendages from their surface called pili. While pili are critical for many functions, such as attachment, motility, and DNA uptake, the factors that regulate their dynamic activity are poorly understood. Here, we describe how an environmental signal induces a signaling pathway to promote the retraction of mannose-sensitive hemagglutinin pili inVibrio cholerae . The retraction of these pili promotes the detachment ofV. cholerae from a surface and may provide a means by whichV. cholerae can respond to changes in its environment.
