Abstract excerpt
Systemic virulence of the phytopathogen Erwinia chrysanthemi 3937 requires a functional iron assimilation system which, in this enterobacterium, is mediated by the siderophore chrysobactin and the outer membrane transport protein Fct. We investigated the regulation of this system by iron. No direct similarity with the Escherichia coli fur gene was found. Insertional mutagenesis allowed isolation of a regulatory...
