感受态刺激肽（CSP）和ComD分别是链球菌的一种信息素及其受体，参与天然遗传转化感受态的调控。我们在这里表明，这些分子经历了积极的选择。本研究是第一次报道由于细菌种群之间的竞争而导致的正选择。
Competence-stimulating peptide (CSP) and ComD of the streptococcal species are a pheromone and its receptor, respectively, involved in the regulation of competence for natural genetic transformation. We show here that these Molecules have undergone positive selection. This study is the first report of positive selection due to competition among bacterial populations.
