The Rhizobiales are an order of Gram-negative Alphaproteobacteria.

The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families Bradyrhizobiaceae, Hyphomicrobiaceae, Phyllobacteriaceae, and Rhizobiaceae contain at least six genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera Bradyrhizobium and Rhizobium . Species of the Methylocystaceae are methanotrophs; they use methanol (CH₃OH) or methane (CH₄) as their sole energy and carbon sources. Other important genera are the human pathogens Bartonella and Brucella , as well as Agrobacterium (genetic engineering).

Natural genetic transformation

Natural genetic transformation has been reported in at least three Rhizobiales species: Agrobacterium tumefaciens , ^[13] Methylobacterium organophilum , ^[14] and Bradyrhizobium japonicum . ^[15] Natural genetic transformation is a sexual process involving DNA transfer from one bacterial cell to another through the intervening medium, and the integration of the donor sequence into the recipient genome by homologous recombination.
