Better together: Reciprocal activation of quorum sensing circuits enhances bacterial communication Many bacteria use quorum sensing to control gene transcription based on population density. This primer explores a recent study in PLOS Biology which found that in Pseudomonas aeruginosa, two quorum-sensing circuits activate each other, enhancing robustness and explaining their redundancy.

Nice review of our work:

The las and rhl QS systems have a reciprocal, synergistic, and unequal relationship. (A,B) 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.

New paper in PLOS Biology. The study considers the interplay between multiple gene regulatory networks, all of which coordinate group behavior in bacteria. We develop a mathematical framework to analyze the interactions and demonstrate that it can […]

No box is safe from an attempted cat occupation by Tee. Amelia, the more sensible one, is watching this foolishness from above. #CatsOfMastodon #caturday
