Evolution of the quorum sensing systems in Pseudomonas aeruginosa can involve both loss of regulon function and network modulation

P. Jayakumar, A. Figueiredo, R. Kümmerli

The paper examines 61 QS mutants of Pseudomonas aeruginosa to determine how mutations in the quorum sensing regulon affect virulence and social traits, finding that some mutations lead to loss of function while others modulate network activity.

Pseudomonas aeruginosa reaches collective decisions via transient segregation of quorum sensing activities across cells

P. Jayakumar, S. A. Thomas, S. P. Brown, R. Kuemmerli

This study shows Pseudomonas aeruginosa cells transiently segregate into low and high receptor expressers to regulate quorum sensing, providing a bet-hedging strategy.
