Xaviernesmea is a genus of bacteria from the family Rhizobiaceae. [1]
Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of (primarily) legumes and other flowering plants.
Agrobacterium is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. Agrobacterium tumefaciens is the most commonly studied species in this genus. Agrobacterium is well known for its ability to transfer DNA between itself and plants, and for this reason it has become an important tool for genetic engineering.
The Rhizobiaceae is a family of Pseudomonadota comprising multiple subgroups that enhance and hinder plant development. 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. The family has been of an interest to scientists for centuries in their ability to associate with plants and modify plant development. The Rhizobiaceae are, like all Pseudomonadota, Gram-negative. They are aerobic, and the cells are usually rod-shaped. Many species of the Rhizobiaceae are diazotrophs which are able to fix nitrogen and are symbiotic with plant roots.
The Hyphomicrobiales are an order of Gram-negative Alphaproteobacteria.
Bradyrhizobium japonicum is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacteria. The species is one of many Gram-negative, rod-shaped bacteria commonly referred to as rhizobia. Within that broad classification, which has three groups, taxonomy studies using DNA sequencing indicate that B. japonicum belongs within homology group II.
Pararhizobium giardinii is a Gram negative root nodule bacteria. It forms nitrogen-fixing root nodules on legumes, being first isolated from those of Phaseolus vulgaris.
Martelella is a genus of Gram-negative, oxidase- and catalase-positive, strictly aerobic, non-spore-forming bacteria from the family of Rhizobiaceae.
Rhizobium indigoferae is a Gram negative root nodule bacteria, which nodulates and forms nitrogen-fixing symbioses with Indigofera species. Its type strain is CCBAU 71714(T).
Pararhizobium capsulatum is a bacterium from the genus Pararhizobium which was isolated from eutrophic forest pond in Germany.
Shinella is a genus of bacteria from the family Rhizobiaceae.
Ensifer medicae is a species of gram-negative, nitrogen-fixing, rod-shaped bacteria. They can be free-living or symbionts of leguminous plants in root nodules. E.medicae was first isolated from root nodules on plants in the genus Medicago. Some strains of E.medicae, like WSM419, are aerobic. They are chemoorganotrophic mesophiles that prefer temperatures around 28 °C. In addition to their primary genome, these organisms also have three known plasmids, sized 1,570,951 bp, 1,245,408 bp and 219,313 bp.
Pararhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Some species of Pararhizobium form an endosymbiotic nitrogen-fixing association with roots of legumes.
Allorhizobium is a genus of Gram-negative soil bacteria. Some species of Allorhizobium form an endosymbiotic nitrogen-fixing association with roots of legumes, while others are known to cause crown gall.
Ciceribacter is a bacterial genus of the family Rhizobiaceae.
Peteryoungia aggregata is a gram-negative bacterium of the genus Peteryoungia.
Pseudorhizobium is a genus of bacteria from the family Rhizobiaceae.
Gellertiella hungarica is a species of Gram-negative bacteria.
Endobacterium is a genus of bacteria from the family Rhizobiaceae.
Peteryoungia is a genus of bacteria from the family Rhizobiaceae.
"Neopararhizobium haloflavum" is a species of bacteria from the family Rhizobiaceae.
