The use of plants to clean-up soils contaminated with trace elements could provide a cheap
and sustainable technology for bioremediation. Field trials suggested that the rate of …

The global population is expected to reach 7 billion by the year 2013. How are we going to
feed the world, prevent further degradation of our environment, and begin to reverse the …

Frequently, crop plants do not take up adequate amounts of iron from the soil, leading to
chlorosis, poor yield and decreased nutritional quality. Extremely limited soil bioavailability …

The ability of intestinal mucosa to absorb dietary ferric iron is attributed to the presence of a
brush-border membrane reductase activity that displays adaptive responses to iron status …

The regulation of tyrosine phosphorylation and associated signalling through antigen,
growth-factor and cytokine receptors is mediated by the reciprocal activities of protein …

Iron uptake from the soil is a tightly controlled process in plant roots, involving specialized
transporters. One such transporter, IRT1, was identified in Arabidopsis thaliana and shown …

Although iron deficiency poses severe nutritional problems to crop plants, to date iron
transporters have only been characterized from the model plant Arabidopsis thaliana. To …

Gene expression in response to Fe deficiency was analyzed in Arabidopsis roots and shoots
through the use of a cDNA collection representing at least 6,000 individual gene sequences …

In eukaryotic cells, ferritin synthesis is controlled by the intracellular iron status. In
mammalian cells, iron derepresses ferritin mRNA translation, whereas it induces ferritin …

Iron-overaccumulating mutants were investigated with respect to changes in epidermal cell
patterning and root reductase activity in response to iron starvation. In all mutants under …
