Fluorescent pseudomonads are γ‐proteobacteria known for their capacity to colonize
various ecological niches. This adaptability is reflected by their sophisticated and diverse …

A variety of bacterial species secrete and take up chelating compounds that enable
acquisition of iron (siderophores). It has become clear that a common feature in regulation of …

Numerous bacteria secrete low molecular weight compounds termed siderophores that
have a high affinity for iron ions. Siderophores have a well-documented role as iron …

ABSTRACT A previously undescribed plant-microbe interaction between a root-colonizing
Streptomyces species, S. lydicus WYEC108, and the legume Pisum sativum is described …

We present the cloning and characterization of an Arabidopsis gene, FRD3, involved in iron
homeostasis. Plants carrying any of the three alleles of frd3 constitutively express three …

The Bacillus subtilis ferric uptake repressor (Fur) protein coordinates a global transcriptional
response to iron starvation. We have used DNA microarrays to define the Fur regulon and …

Pyoverdines, the main siderophores of fluorescent pseudomonads, contain a peptide
moiety, different for each pyoverdine, and an identical chromophore. While it has been …

Recently it has been observed that multicopper oxidases are present in a number of
microbial genomes, raising the question of their function in prokaryotes. Here we describe …

The diphtheria toxin repressor (DtxR) uses Fe2+ as a corepressor and inhibits transcription
from iron-regulated promoters (IRPs) in Corynebacterium diphtheriae. A new IRP …

In nature, most bacteria live in close association with surfaces as complex communities
referred to as biofilms. Community members within these compact microbial consortia show …
