An isolate of Pseudomonas putida has been foundto aggressively colonize root tips and induce plant resistanceto Fusarium wilt. However, P. putida mutants lacking Fesuperoxidedismutase (SOD) or both FeSOD and MnSODactivities are less competitive in root tip colonization. In thecurrent study, the growth of an FeSOD mutant was found tobe more sensitive than that of the wild-type or a MnSODmutant to oxidative stress imposed by paraquat treatment andculturing with the soil fungus Talaromyces flavus, whichgenerates reactive oxygen species. Also, the loss of culturabilitywith an aging stationary-phase culture was greater for adouble SOD mutant than an FeSOD mutant, while noreduction in culturability was observed with the wild-type anda MnSOD mutant under the same protracted stationary-phaseconditions. Accordingly, it was concluded that FeSODactivity is the major form of SOD in P. putida and plays anessential role in survival under stress conditions whenincreased oxidative stress is encountered.
