The Rhizobium leguminosarum regulator IrrA affects the transcription of a wide range of genes in response to Fe availability.

Molecular genetics and genomics : MGG - 1 Jun 2006

Abstract excerpt

We show that an unusual transcriptional regulator, called IrrA, regulates many genes in the symbiotic N2-fixing bacterium Rhizobium leguminosarum in response to iron availability. Several operons in R. leguminosarum are expressed at lower levels in cells grown in Fe-depleted compared to Fe-replet...
