Reversal of the choline-induced growth defect upon expression of the pore-blocking construct FliK-TOP7. The experimental strain (left-hand panel) contained the FliK-TOP7 construct in the chromosomal ara locus; the control strain (right-hand panel) lacked the pore-blocking construct but was otherwise the same. Expression of ΔMet-FliP was induced by 10 μM salicylate; induction of FliK-TOP7 was with 0.01% arabinose. A representative experiment is shown.
