Analysis of Mutations Affecting Cooperation in Pseudomonas aeruginosa Populations

Creator:

Robinson, Tanner M.

Abstract:

In a process called quorum sensing (QS), the bacterial pathogen Pseudomonas aeruginosa uses small diffusible signals to coordinate cooperative behaviors via secreted “public goods”. Under QS-dependent growth conditions, social cheaters arise with mutations in lasR, the gene for the primary QS signal receptor. These cheaters do not produce public goods....

Evolution of a streamlined cooperator in Pseudomonas aeruginosa quorum sensing

Creator:

Huie, Jessica L.

Abstract:

Social behavior leading to the production of common goods is prone to exploitation. One such behavior in Pseudomonas aeruginosa is quorum sensing (QS), by which the bacteria produce signals to regulate extracellular common goods. Exploitation comes in the form of cheaters which have a mutation in the central quorum sensing...
