Rhizobia are a diverse group of symbiotic alpha-proteobacterial diazotrophs which enter a relationship with specific leguminous plants, in which the plant supplies the bacteria with required compounds whilst the bacteria reduce atmospheric nitrogen into ammonia that the plant uses as a nitrogen source. Modification of rhizobial strains has produced mutants more effective at fixing nitrogen, which in turn results in an increase in biomass of host plants under laboratory conditions but these strains are frequently out competed by wild-type strains in field studies or lost in the intervening years of a crop rotation. This study aimed to establish a library of mutants and a system for screening these strains en masse to identify some of the genes involved in competitive rhizosphere colonization in Rhizobium leguminosam.
