Legume Haemoglobins: Symbiotic Nitrogen Fixation Needs Bloody Nodules
How do plants create an environment in which symbiotic bacteria can reduce enough N2 to provide the plant with sufficient ammonium for growth? Gene silencing has now been used to show that legume haemoglobins are crucial.
متن کاملSymbiotic Nitrogen Fixation in Legume Nodules: Metabolism and Regulatory Mechanisms
The special issue "Symbiotic Nitrogen Fixation in Legume Nodules: Metabolism and Regulatory Mechanisms" aims to investigate the physiological and biochemical advances in the symbiotic process with an emphasis on nodule establishment, development and functioning. The original research articles included in this issue provide important information regarding novel aspects of nodule metabolism and v...
متن کاملThe Legume Root Nodule: From Symbiotic Nitrogen Fixation to Senescence
Biological nitrogen fixation (BNF) is the biological process by which the atmospheric nitrogen (N2) is converted to ammonia by an enzyme called nitrogenase. It is the major source of the biosphere nitrogen and as such has an important ecological and agronomical role, accounting for 65 % of the nitrogen used in agriculture worldwide. The most important source of fixed nitrogen is the symbiotic a...
متن کاملNitrogen fixation and carbon metabolism in legume nodules.
A large amount of energy is utilized by legume nodules for the fixation of nitrogen and assimilation of fixed nitrogen (ammonia) into organic compounds. The source of energy is provided in the form of photosynthates by the host plant. Phosphoenol pyruvate carboxylase (PEPC) enzyme, which is responsible for carbon dioxide fixation in C4 and crassulacean acid metabolism plants, has also been foun...
متن کاملSymbiotic Nitrogen Fixation.
Biosphere nitrogen is subjected to rapid turnover, and because it is eventually lost as nitrogen into the atmosphere, its maintenance requires continuous replenishment with reduced nitrogen from atmospheric nitrogen. Biological reduction of nitrogen to ammonia can be performed only by some prokaryotes and is a highly oxygen-sensitive process. The most efficient nitrogen fixers establish a symbi...
