New paper from the group out in BMC Microbiology. We show Pseudomonas granadensis is an endophyte, and that it has plant growth promoting benefits. 🌱🦠

Bacterial #QuorumSensing is often assumed to follow a strict hierarchy. This study finds that #Pseudomonas aeruginosa instead uses a reciprocal, cooperative system that enhances responsiveness to population density & environmental changes @PLOSBiology https://plos.io/3I7DhRG

The las and rhl QS systems have a reciprocal, synergistic, and unequal relationship. Top: Single-signal models demonstrate that the summed effects of single signals (3 oxo C12 HSL alone, red; C4 HSL alone, orange) cannot account for the maximal expression of lasI or rhlI. The upper green, flat surfaces in the plots indicate the maximum mean expression level measured across all combinations of signal concentrations while the lower semi-transparent surfaces mark the sum of single signal effects. The plotted points represent observed expression levels when C4 HSL is withheld (red) and when 3 oxo C12 HSL is withheld (yellow). Lines indicate the model predictions. Bottom: Multi-signal non-linear models capture the synergistic effects of both signals and match observed expression levels. Model estimates are shown as grid lines. Horizontal bars show the mean value of expression observed at each combination of signal concentrations. Lines extend from these mean values to the relevant grid point for clarity. Right: Data show that relationship of the las and rhl systems is reciprocal, and the multi-signal model quantifies the strength of those interactions. In particular, it reveals the contribution of both signals to the maximum fold-change in expression of both synthases. The charts in this panel summarize the contribution of 3 oxo C12 HSL (red), C4 HSL (yellow), and the synergistic combination of both (orange).

A plant's #microbiome can protect it against detrimental bacterial strains. This study shows that competition among #Pseudomonas #bacteria in synthetic bacterial communities determines how well they can protect #Arabidopsis; a single competitive strain can suffice @PLOSBiology https://plos.io/4o96mN1

Arabidopsis thaliana Col-0 phenotypes grown on MS agar plates alone (MS) or in co-cultivation with the indicated SynComs (AtSC5, AtSC6, LjSC5, LjSC6), and after treatment with mock (Control), R401 wild-type (R401wt) or R401 ΔpvdY ΔphlD (R401mut) strain. Scale bar corresponds to 1 cm.

Innerhalb genetisch identischer Bakterienpopulationen können verschiedene Subpopulationen auftreten. Forscher:innen des HZI zeigen in einer aktuellen Studie @PNASNews, wie dieser Effekt dem Erreger #Pseudomonas aeruginosa hilft, Infektionen zu etablieren.

We know that gram-negative bacteria release extracellular vesicles into their surrounding environment--but why?
