TL;DR: This study suggests that AHL degradation is an integral part of the whole autoinducer circuit of P. putida IsoF, allowing quantitative predictions and a further understanding of the QS-based regulations in this bacterium.

TL;DR: To investigate the impact of the application of Proradix® on the structure of the dominant root-associated bacterial community of barley, T-RFLP analyses were performed and only a transient community effect was found until 3 weeks post-application.

TL;DR: Interestingly, the bacterial community associated with soybean roots after glyphosate application not only demonstrated effective resilience after the disturbance but in addition, T-RF diversity also increased in comparison to the untreated control samples, suggesting that bacterial diversity was even stimulated in the rhizosphere after glyphosateApplication.

TL;DR: The quorum-sensing system in P. putida IsoF is remarkably stable under different environmental conditions, and in all chemostat experiments, the signal concentration decreased strongly after a peak, because emerging lactonase activity led to a lower concentration under steady-state conditions.

TL;DR: This study provides a cost-effective, fast, and sensitive analytical method for detection of HSLs/HSs in biological samples without complex sample preparation and will offer a quick idea about B. cepacia activities.
