This study demonstrates that conjugated symbiosis islands can generate nitrogen-fixing endosymbionts in rhizobia, often as mutualists rather than exploiters, with transmission dynamics influenced by phylogenetic relatedness.

This paper identifies the regulatory DNA elements and amino acid residues in NreA that control Ni tolerance in Mesorhizobium strains from serpentine soils.

The paper investigates the phylogenetic congruence of mobile genetic elements and host chromosomes in wild bacteria, finding that they often co-inherit vertically and that environmental factors influence horizontal transfer.
