Genetic regulation of nitrogen fixation in rhizobia.
This review presents a comparison between the complex genetic regulatory networks that control nitrogen fixation in three representative rhizobial species, Rhizobium meliloti, Bradyrhizobium japonicum, and Azorhizobium caulinodans. Transcription of nitrogen fixation genes (nif and fix genes) in these bacteria is induced primarily by low-oxygen conditions. Low-oxygen sensing and transmission of ...
متن کاملEvolutionary Dynamics of Nitrogen Fixation in the Legume–Rhizobia Symbiosis
The stabilization of host-symbiont mutualism against the emergence of parasitic individuals is pivotal to the evolution of cooperation. One of the most famous symbioses occurs between legumes and their colonizing rhizobia, in which rhizobia extract nutrients (or benefits) from legume plants while supplying them with nitrogen resources produced by nitrogen fixation (or costs). Natural environmen...
متن کاملIncreasing Level of Ammonia in the Surface Raw Water Source at Dhaka, Bangladesh
In 2004,ammonia concentration in raw water of Sitalakhya River at the eastern periphery of Dhaka was found higher than the expected rate of 4 mg/Lforecasted in feasibility studies,with a value of about 8 mg/L, which could not be removed by conventional treatment chain employed at Dhaka, hence, recentlyan ammonia removal plant has been constructed. This important background has ledto the current...

متن کاملIs Blood Protein Amide Nitrogen a Source of Urinary Ammonia? Iii. on the Question of Synthesis of Protein Amides from Ammonia *
Synthesis of protein amides from ammonia has been proposed (Bliss (1)) as a tissue function whose demonstration is of cardinal importance to the development of the theory that blood protein amide nitrogen represents detoxified ammonia, first employed in tissues for neutralization of acid, in course of transport to the kidneys where the amide nitrogen reappears as urinary ammonia. Questionable i...
