Question: A quorum sensing response in a hypothetical organism (let’s call it Vibrio imaginarium) results in upregulation of one gene (qsg1) and downregulation of another (qsg2). Assume that preliminary experiments have been performed and these experiments have shown that homoserine lactone functions as the autoinducer. You are interested in how the […]
