Rhizobiaceae

The Rhizobiaceae is a family of Pseudomonadota comprising multiple subgroups that enhance and hinder plant development.<ref name=":0">Template:Cite book</ref> Some bacteria found in the family are used for plant nutrition and collectively make up the rhizobia. Other bacteria such as Agrobacterium tumefaciens and Rhizobium rhizogenes severely alter the development of plants in their ability to induce crown galls or hairy roots, respectively.<ref name=":0" /> The family has been of an interest to scientists for centuries in their ability to associate with plants and modify plant development.<ref name=":0" /> The Rhizobiaceae are, like all Pseudomonadota, Gram-negative. They are aerobic, and the cells are usually rod-shaped.<ref name=Bergey>Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005).
