概要	To identify a gene encoding the stator protein required for motility, delta motAB, delta motCD, and delta motABCD mutants were generated. The delta motCD mutant had remarkably reduced and the delta motABCD mutant completely abolished swimming motilities, whereas the delta motAB mutant retained some degree of these abilities. The delta motCD and delta motABCD mutants did not produce N-acyl-homoserine lactones (AHLs), quorum-sensing molecules in this pathogen, and remarkably reduced the ability to cause disease in host tobacco leaves, as we previously observed in the delta fliC mutant strain. These results strongly indicate that both stator pairs in Pta 6605 are proton-dependent and that MotCD is important for not only flagellar motility but also for production of AHLs and the ability to cause disease in host plants.
