Ecophysiology of iron homeostasis in plants

Mitochondrial iron transport and homeostasis in plants

Iron (Fe) is an essential nutrient for plants and although the mechanisms controlling iron uptake from the soil are relatively well understood, comparatively little is known about subcellular trafficking of iron in plant cells. Mitochondria represent a significant iron sink within cells, as iron is required for the proper functioning of respiratory chain protein complexes. Mitochondria are a si...

Iron homeostasis in plants – a brief overview

Iron plays a crucial role in biochemistry and is an essential micronutrient for plants and humans alike. Although plentiful in the Earth's crust it is not usually found in a form readily accessible for plants to use. They must therefore sense and interact with their environment, and have evolved two different molecular strategies to take up iron in the root. Once inside, iron is complexed with ...

Iron homeostasis and iron acquisition in plants: maintenance, functions and consequences.

Iron (Fe) is fourth most abundant element in the earth’s crust and is an essential nutrient for almost all organisms. Its solubility and availability are very changeable depending on soil pH and Eh and as a result, iron can be deficient under alkaline and oxidative conditions, whereas it can be present in excess under acidic and submerged conditions: both situations can generate serious nutriti...

Ecophysiology of different filamentous Alphaproteobacteria in industrial wastewater treatment plants.

The ecophysiology of five filamentous species affiliated to the Alphaproteobacteria was investigated in industrial activated sludge systems. The five species, 'Candidatus Alysiosphaera europaea', 'Candidatus Monilibacter batavus', 'Candidatus Alysiomicrobium bavaricum', 'Candidatus Sphaeronema italicum' and Meganema perideroedes, are very abundant in industrial wastewater treatment plants and a...
