| Research Abstract |
The present study showed that the Sinorhizobium meliloti TolC, an outer membrane component of multidrug efflux pump, was involved in endophytic colonization of rice seedlings. A tolC knockout mutant was more susceptible than wild type to various plant-derived antimicrobial compounds, suggesting that the extrusion of such toxic substances by the TolC-dependent efflux pumps is important for adaptation of S. meliloti to the host environment.
