Motility plays an essential role in bacterial fitness and colonization in the plant environment, since it favors nutrient acquisition and avoidance of toxic substances, successful competition with(More)
Conjugal transfer of Sinorhizobium meliloti and Rhizobium etli symbiotic plasmids are repressed by the transcriptional regulator RctA. Here we report on new key players in the signal transduction(More)
Sinorhizobium meliloti can translocate over surfaces. However, little is known about the regulatory mechanisms that control this trait and its relevance for establishing symbiosis with alfalfa(More)
