Journal ArticleDOI
Maize yellow stripe1 encodes a membrane protein directly involved in Fe(III) uptake.
Catherine Curie,Zivile Panaviene,Clarisse Loulergue,Stephen L. Dellaporta,Jean-François Briat,Elsbeth L. Walker +5 more
TL;DR: It is shown that ys1 is a membrane protein that mediates iron uptake, and is an important step in understanding iron uptake in grasses, and has implications for mechanisms controlling iron homeostasis in all plants.
Journal ArticleDOI
Rapid Induction of Distinct Stress Responses after the Release of Singlet Oxygen in Arabidopsis
Roel op den Camp,Dominika Przybyla,Christian Ochsenbein,Christophe Laloi,Chanhong Kim,Antoine Danon,Daniela Wagner,Éva Hideg,Cornelia Göbel,Ivo Feussner,Mena Nater,Klaus Apel +11 more
TL;DR: Results demonstrate that singlet oxygen does not act primarily as a toxin but rather as a signal that activates several stress-response pathways and its biological activity in Arabidopsis exhibits a high degree of specificity that seems to be derived from the chemical identity of this reactive oxygen species and/or the intracellular location at which it is generated.
Journal ArticleDOI
Expression of the IRT1 metal transporter is controlled by metals at the levels of transcript and protein accumulation.
TL;DR: The results suggest that the expression of IRT1 is controlled by two distinct mechanisms that provide an effective means of regulating metal transport in response to changing environmental conditions.
Journal ArticleDOI
Contribution of the arbuscular mycorrhizal symbiosis to heavy metal phytoremediation.
Vera Göhre,Uta Paszkowski +1 more
TL;DR: Current knowledge about the contribution of the AM symbiosis to phytoremediation of heavy metals is summarized and plants in symbiosis with AM fungi have the potential to take up HM from an enlarged soil volume.

CD45 is a JAK phosphatase and negatively regulates cytokine receptor signalling
Junko Irie-Sasaki,Junko Irie-Sasaki,Takehiko Sasaki,Takehiko Sasaki,Wataru Matsumoto,Anne Opavsky,Mary Cheng,G. Grant Welstead,Emily K. Griffiths,Connie M. Krawczyk,Christopher D. Richardson,Karen Aitken,Norman N. Iscove,Gary A. Koretzky,Pauline Johnson,Peter Liu,David M. Rothstein,Josef M. Penninger,Josef M. Penninger +18 more
TL;DR: Functionally, CD45 negatively regulates interleukin-3-mediated cellular proliferation, erythropoietin-dependent haematopoieisis and antiviral responses in vitro and in vivo.

The ferritins: molecular properties, iron storage function and cellular regulation☆
Pauline M. Harrison,Paolo Arosio +1 more
TL;DR: A great deal of research effort is now concentrated on two aspects of ferritin: its functional mechanisms and its regulation and the apparent links between iron and citrate metabolism through a single molecule with dual function are described.
Journal ArticleDOI
Protein damage and degradation by oxygen radicals. I. general aspects.
TL;DR: The results indicate a general sensitivity of proteins to oxygen radicals and indicate that proteins which have been denatured by .OH can be recognized and degraded rapidly and selectively by intracellular proteolytic systems.
Journal ArticleDOI
Molecular control of vertebrate iron metabolism: mRNA-based regulatory circuits operated by iron, nitric oxide, and oxidative stress
Matthias W. Hentze,Lukas C. Kühn +1 more
TL;DR: The discovery of two IRE-regulated mRNAs encoding enzymes of the mitochondrial citric acid cycle may represent the beginnings of elucidating regulatory coupling between iron and energy metabolism, and IRP-1 has highlighted an unexpected role for iron sulfur clusters as post-translational regulatory switches.
Journal ArticleDOI
A novel iron-regulated metal transporter from plants identified by functional expression in yeast
TL;DR: In Arabidopsis, IRT1 is expressed in roots, is induced by iron deficiency, and has altered regulation in plant lines bearing mutations that affect the iron uptake system, providing the first molecular insight into iron transport by plants.
Journal ArticleDOI
Iron: Nutritious, Noxious, and Not Readily Available.
Mary Lou Guerinot,Y. Yi +1 more
TL;DR: The problem that soil-based organisms have with iron is not one of abundance, since iron ranks fourth among a11 elements on the surface of the earth, but rather one of availability in aerobic environments at biological pH, which is far below that required for the optimal growth of plants or microbes.
