The topic of fixation of nitrogen by bacteria was introduced as an example of a symbiotic interaction of bacteria with their hosts, focusing on the problem of nitrogen source availability for organisms and the role played by bacteria that convert atmospheric nitrogen into ammonia or nitrate. The key steps , molecules and genes involved in the initial recognition of bacteria and host until the formation of mature symbiosomes and nitrogen fixing nodules were presented and discussed.
