Abstract

A cloned Rhizobium leguminosarum gene, termed rpoI, when transferred to wild-type strains, caused overproduction of the siderophore vicibactin. An rpoI mutant was defective in Fe uptake but was unaffected in symbiotic N fixation. The RpoI gene product was similar in sequence to extra-cytoplasmic s factors of RNA polymerase. Transcription of rpoI was reduced in cells grown in medium that was replete with Fe.
