<jats:title>ABSTRACT</jats:title>
<jats:p>
Frameshift mutations in a poly(G) track at the
<jats:italic>flhB</jats:italic>
gene of
<jats:italic>Pseudomonas putida</jats:italic>
DOT-T1E are responsible for the diminished swimming of this strain on semisolid medium, which contrasts with the high swimming ability of
<jats:italic>P. putida</jats:italic>
KT2440, which does not exhibit a poly(G) track at the
<jats:italic>flhB</jats:italic>
gene. We previously showed that a mutant lacking FlhB was more sensitive to solvents than the wild-type strain (Segura et al., J. Bacteriol., 183:4127-4133, 2001). In this study, we show that swimming ability correlates with solvent tolerance in
<jats:italic>P. putida</jats:italic>
DOT-T1E, so that growth conditions favoring a functional
<jats:italic>flhB</jats:italic>
gene (growth on semisolid medium) resulted in increased innate tolerance to a sudden toluene shock.
