Role of the regulatory gene rirA in the transcriptional response of Sinorhizobium meliloti to iron limitation.

Applied and environmental microbiology - 1 Oct 2005

Abstract excerpt

A regulatory network of Sinorhizobium meliloti genes involved in adaptation to iron-limiting conditions and the involvement of the rhizobial iron regulator gene (rirA) were analyzed by mutation and microarray analyses. A constructed S. meliloti rirA mutant exhibited growth defects and enhanced H2O2 sensitivity in the presence of iron, but symbiotic nitrogen fixation was not affected. To identify iron-responsive...
