N2 - Pseudomonas syringae pv. tabaci 6605 (Pta6605) is a causal agent of wildfire disease in host tobacco plants. Pta6605 is a foliar pathogen that requires chemotaxis and aerotaxis for plant infection. Pta6605 has seven che gene clusters and 54 potential chemoreceptor genes. Pta6605 is thought to have three chemosensory pathways, Che, Wsp, and Chp from analysis of the CheA/CheW binding motif. However, a chemoreceptor for the Che2 chemosensory pathway was not identified. Mutational analysis revealed that che genes in cluster I, chemoreceptor genes for γ-aminobutyric acid and proteinogenic amino acids, are required for plant infection. In this mini-review, we summarized the findings about chemotaxis and aerotaxis in Pta6605 obtained so far.
