Biological nitrogen fixation in rhizobia occurs primarily in root or stem nodules and is induced by the bacteria present in legume plants. This symbiotic process has fascinated researchers for over a century, and the positive effects of legumes on soils and their food and feed value have been recognized for thousands of years. Symbiotic nitrogen fixation uses solar energy to reduce the inert N2 gas to ammonia at normal temperature and pressure, and is thus today, especially, important for sustainable food production. Increased productivity through improved effectiveness of the process is seen as a major research and development goal. The interaction between rhizobia and their legume hosts has thus been dissected at agronomic, plant physiological, microbiological and molecular levels to produce ample information about processes involved, but identification of major bottlenecks regarding efficiency of nitrogen fixation has proven to be complex. We review processes and results that contributed to the current understanding of this fascinating system, with focus on effectiveness of nitrogen fixation in rhizobia.

根瘤菌固氮的有效性。
根瘤菌中的生物固氮主要发生在根或茎节中，并由豆科植物中存在的细菌诱导。一个多世纪以来，这种共生过程一直让研究人员着迷，数千年来，豆类对土壤及其食物和饲料价值的积极影响已得到认可。共生固氮利用太阳能在常温常压下将惰性N 2气体还原为氨，因此在今天对于可持续粮食生产尤其重要。通过提高流程效率来提高生产率被视为主要的研发目标。因此，根瘤菌与其豆科植物宿主之间的相互作用已在农艺、植物生理、微生物和分子水平上进行了剖析，以产生有关所涉及过程的充足信息，但事实证明，确定有关固氮效率的主要瓶颈是复杂的。我们回顾了有助于当前理解这一迷人系统的过程和结果，重点关注根瘤菌固氮的有效性。
