Description
Qin Xiong and co-authors found in 2024 that a bacterial signal relieves stress-induced dormancy in a soil Bacillus species. Bacteria coordinate group behaviour through quorum sensing signals. One widespread signal, autoinducer-2, was little explored in Bacilli, though known to shape many processes in other bacteria.
The work shows the signal blocks the start of sporulation, the process that forms dormant spores. It acts through a phosphatase and a DNA-binding regulator, strengthening their binding so the regulator stays inactive. Lab chemistry confirmed the interaction. The signal could be shared across species and worked the same in varied soils, revealing a new role and control route for this molecule.
