RESUMO
Pseudomonas aeruginosa possesses two aerotaxis transducers, Aer and Aer-2. A deletion-insertion mutation of alternative sigma factor RpoS eliminated Aer-2-mediated aerotaxis but not Aer-mediated aerotaxis. Transcriptional analysis revealed that cheY2, cheA2, cheW2, and aer-2 were expressed in an RpoS-dependent manner as a single transcript.
