A moderate toxin, GraT, modulates growth rate and stress tolerance of Pseudomonas putida.


Chromosomal toxin-antitoxin (TA) systems are widespread among free-living bacteria and are supposedly involved in stress tolerance. Here, we report the first TA system identified in the soil bacterium Pseudomonas putida. The system, encoded by the loci PP1586-PP1585, is conserved in pseudomonads and belongs to the HigBA family. The new TA pair was named… (More)
