Abstract We have analyzed the ability of single site insertion mutants of Rhizobium meliloti 1021 defective in various components of a high-affinity iron transport system to produce nodules, fix nitogen and promote plant growth. Our results indicate that a high-affinity iron transport system may significantly increase the ability of the differentiated form of the bacterium to fix nitrogen and induce an increase in plant growth.
