Medicago truncatula represents a model plant species for understanding legume–bacteria interactions. M. truncatula roots form a specific root–nodule symbiosis with the nitrogen-fixing bacterium Sinorhizobium meliloti. Symbiotic nitrogen fixation generates high iron (Fe) demands for bacterial nitrogenase holoenzyme and plant leghemoglobin proteins.(More)
We looked for bacterial strains with antifungal activity in the sorghum rhizosphere. A prescreening procedure to search for hemolytic activity among the isolated strains allowed us to detect good fungitoxic activity in a bacterial isolate that we named UM96. This bacterial isolate showed strong growth inhibition in bioassays against the pathogens(More)
Studies on Rhizobium-legume symbiosis show that trehalose content in nodules under drought stress correlates positively with an increase in plant tolerance to this stress. Fewer reports describe trehalose accumulation in mycorrhiza where, in contrast with rhizobia, there is no flux of carbohydrates from the microsymbiont to the plant. However, the trehalose(More)
