Regulation of iron-siderophore uptake in a diazotrophic cyanobacterium Anabaena anabaena 7120
The Indian Journal of Agricultural Sciences, 2014 The regulation of 55Fe-siderophore uptake of was studied in a diazotrophic cyanobacterium Anabaena 7120. The uptake up to 20 min was found to be biphasic, a rapid first and steady second phase.

Iron metabolism in trypanosomatids, and its crucial role in infection. [PDF]
, 2010 Iron is almost ubiquitous in living organisms due to the utility of its redox chemistry. It is also dangerous as it can catalyse the formation of reactive free radicals - a classical double-edged sword.

Iron uptake and iron-repressible polypeptides in Yersinia pestis [PDF]
Infection and Immunity, 1996 Pigmented (Pgm+) cells of Yersinia pestis are virulent, are sensitive to pesticin, adsorb exogenous hemin at 26 degrees C (Hms+), produce iron-repressible outer membrane proteins, and grow at 37 degrees C in iron-deficient media. These traits are lost upon spontaneous deletion of a chromosomal 102-kb pgm locus (Pgm-).

59Fe Uptake Assays in Paracoccidioides Species
Bio-Protocol, 2016 Iron is an essential micronutrient required for virtually all organisms. This fact is related to the ability of the transition metal to exist in two oxidation states, the reduced ferrous (Fe2+) and the oxidized ferric (Fe3+).

Paracoccidioides spp. FERROUS AND FERRIC IRON ASSIMILATION PATHWAYS
Frontiers in Microbiology, 2015 Iron is an essential micronutrient for almost all organisms, including fungi. Usually, fungi can uptake iron through receptor-mediated internalization of a siderophore or heme, and/or reductive iron assimilation (RIA).

Uptake Efficiency of Iron in Different Wheat Varieties
مجله آب و خاک, 2014 With due attention to the low availability of iron in calcareous soils and different ability of plant species in iron acquisition, the study and identification of iron-efficient plants is necessary to reduce the use of chemical fertilizers. In this way,

The role of the ferric uptake regulator (Fur) in regulation of Helicobacter pylori iron uptake [PDF]
, 2002 Background. Availability of the essential nutrient iron is thought to vary greatly in the gastric mucosa, and thus the human gastric pathogen Helicobacter pylori requires regulatory responses to these environmental changes.

The “Little Iron Waltz”: The Ternary Response of Paracoccidioides spp. to Iron Deprivation
Journal of Fungi, 2020 Paracoccidioides is a genus of thermodimorphic fungi that causes paracoccidioidomycosis. When in the host, the fungus undergoes several challenges, including iron deprivation imposed by nutritional immunity.
