Ethylene Chemotaxis in Pseudomonas aeruginosa and Other Pseudomonas Species

Hye‐Eun Kim, Maiko Shitashiro, Akio Kuroda, Noboru Takiguchi, Junichi Kato

Abstract

Pseudomonas aeruginosa strain PAO1 was attracted by ethylene. Assays of a set of mutants containing deletions in 26 potential methyl-accepting chemotaxis protein genes revealed that tlpQ (PA2654) encodes the chemoreceptor for positive chemotaxis to ethylene. Pseudomonas fluorescens, Pseudomonas putida, and Pseudomonas syringae strains also exhibited positive chemotaxis toward ethylene.
