Genomic analysis of the Lotus tenuis symbiont Aminobacter ciceronei BA135 reveals horizontal acquisition of a Mesorhizobium symbiosis island
Legume-rhizobia symbioses are critical for biological nitrogen fixation in marginal soils, yet the occurrence of nitrogen-fixing symbioses in lineages outside the classical rhizobial genera suggest that the evolutionary boundaries of this association are broader than traditionally assumed. We report the complete ge...
