In vitro evolution of Listeria monocytogenes reveals selective pressure for loss of SigB and AgrA function at different incubation temperatures.

This study shows that Listeria monocytogenes evolves to lose SigB or Agr function under different temperatures, increasing competitive fitness in specific conditions.

Acid stress signals are integrated into the σB-dependent general stress response pathway via the stressosome in the food-borne pathogen Listeria monocytogenes

This study identifies the role of the stressosome in acid stress signaling and σB activation in Listeria monocytogenes, showing phosphorylation of RsbS and RsbR1 is essential for this process.
