Regulation of the iron uptake genes in Pseudomonas fluorescens M114 by pseudobactin M114: the pbrA sigma factor gene does not mediate the siderophore regulatory response.

Abstract

The iron-regulated PbrA sigma factor dictates the production of the siderophore, pseudobactin M114, and its cognate outer membrane receptor, PbuA, in Pseudomonas fluorescens M114. However, the siderophore molecule also has a role in regulating the expression of the siderophore biosynthetic and siderophore receptor genes in P. fluorescens M114. This is based… (More)
