In return, the bacteria provides the plant with nitrogen in forms that the plant can take in. Nitrogen fixing bacteria change nitrogen from the air into nitrogen compounds such as ammonia, nitrate, and nitrogen dioxide. They do so, through two living arrangements. One's as free living bacteria in the soil. The other's in association with plants of the Fabaceae and Leguminosae families, such as beans and peas.
some bacteria can absorb N2 and convert it to ammonia, nitrates, and nitrites Describe the relationship between Rhizobia and legumes. Rhizobia are bacteria that are found in nodules in roots of legumes, provide the plant ammonia in return for protection and sugar How do nitrogen-fixing bacteria colonize root plants? 1. recognition of bacteria and plant (plant releases flavenoids, bacteria produce Nod factors) 2. Nod factors bind to root-hair surface, rhizobia multiply 3. Rhizobia enter epidermal cell through infection thread 4. once invading root cortex, infection thread bursts and releases rhizobia into cortex cells
