The '''Rhizobiaceae''' is a family of [[Pseudomonadota]] comprising multiple subgroups that enhance and hinder plant development.<ref name=":0">{{Cite book|url=https://books.google.com/books?id=2HToCAAAQBAJ&q=Rhizobiaceae&pg=PR13|title=The Rhizobiaceae: Molecular Biology of Model Plant-Associated Bacteria|last1=Spaink|first1=Herman P.|last2=Kondorosi|first2=Ádam|last3=Hooykaas|first3=Paul|date=2012-12-06|publisher=Springer Science & Business Media|isbn=9789401150606|language=en}}</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 organism|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).
