Rhizobiaceae
The Rhizobiaceae is a family of Pseudomonadota comprising multiple subgroups that enhance and hinder plant development.[2] 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.[2] The family has been of an interest to scientists for centuries in their ability to associate with plants and modify plant development.[2] The Rhizobiaceae are, like all Pseudomonadota, Gram-negative. They are aerobic, and the cells are usually rod-shaped.[3] Many species of the Rhizobiaceae are diazotrophs which are able to fix nitrogen and are symbiotic with plant roots.
