Rhizobium is defined as a gram-negative bacterium that serves as a nitrogen fixer in leguminous plants, forming root nodules to convert atmospheric nitrogen into ammonia and nitrates, which are then utilized by the plants for synthesizing amino acids and nucleotides. AI generated definition based on: Journal of Biotechnology, 2022 Learn about Rhizobium , a group of bacteria that can convert nitrogen gas into organic molecules and form symbiotic relationships with legumes. Find out how Rhizobium interacts with plants, what factors affect its gene expression, and what are its taxonomy and phylogeny. Rhizobium is a remarkable bacterium known for its unique symbiotic relationship with the roots of leguminous plants. Found primarily in root nodules of plants like peas, beans, and lentils, Rhizobium plays a crucial role in biological nitrogen fixation. This process converts atmospheric nitrogen, which plants cannot directly use, into ammonia—a soluble form that plants can absorb. Ammonia serves as a vital nutrient, enhancing soil fertility and promoting plant growth, especially in ... 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.
