what is rimbizioum bacterium
Answers
Answer:
Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of legumes and Parasponia.
The bacteria colonize plant cells within root nodules, where they convert atmospheric nitrogen into ammonia using the enzyme nitrogenase and then provide organic nitrogenous compounds such as glutamine or ureides to the plant. The plant, in turn, provides the bacteria with organic compounds made by photosynthesis. This mutually beneficial relationship is true of all of the rhizobia, of which the genus Rhizobium is a typical example. Rhizobium is also capable to solubilize phosphorus.
The taxon has largely subsumed genera Agrobacterium Conn 1942 and Allorhizobium following in phelogenetic research from the late 1990s to the early 2000s when the two genera were shown to be not very different from Rhizobium. A confusing result is that Agrobacterium tumefaciens, now Rhizobium radiobacter, remains as the type species of Agrobacterium. The division of genera under Rhizobiaceae remains fluid.
