A Rhizobium leguminosarum mutant defective in symbiotic iron acquisition.

Journal of bacteriology - 1 Feb 1990

Nadler K D, Johnston A W, Chen J W, John T R

Abstract excerpt

Iron acquisition by symbiotic Rhizobium spp. is essential for nitrogen fixation in the legume root nodule symbiosis. Rhizobium leguminosarum 116, an ineffective mutant strain with a defect in iron acquisition, was isolated after nitrosoguanidine mutagenesis of the effective strain 1062. The pop-1 mutation in strain 116 imparted to it a complex phenotype, characteristic of iron deficiency: the accumulation of...
