Genomic plasticity, stress tolerance, and a distinctive pSymA in the symbiotic bacterium Sinorhizobium meliloti IRAMC:0087
Arid ecosystems promote the emergence of rhizobial strains adapted to severe abiotic stress while retaining symbiotic competence. Here, we characterize IRAMC:0087, a rhizobial strain isolated from root nodules of the Saharan shrub Calobota saharae in southern Tunisia. Phenotypic assays showed high tolerance to heat...
