Research Abstract |
We found that Pseudomonas strains show chemotactic responses to plant-related compounds including amino acids, malate, and ethylene. We identified P.aeruginosa PA26541, P.putida Pput_3489, and P.aeruginosa PA2652 as chmotactic sensory proteins for ethylene, amino acids, and malate, respectively. Molecular analysis of chemotaxis to trichloroethylene (TCE) in TCE-degrading bacterium P.putida F1 revealed that Pput_6181 and Pput_3489 serve as sensory proteins for positive and negative chemotaxis to TCE, respectively.
