||Positive selection in the CSP-ComD system of streptococcal species.
|| 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.
