Some plants can hyperaccumulate metal ions that are toxic to virtually all other organisms at
low dosages. This trait could be used to clean up metal-contaminated soils. Moreover, the …

The maintenance of Mg 2+ homeostasis in the plant is essential for viability. This review
describes Mg 2+ functions and balancing in plants, with special focus on the existing …

Plants are the principal source of iron in most diets, yet iron availability often limits plant
growth. In response to iron deficiency, Arabidopsis roots induce the expression of the …

Because plant wilting has been described as a consequence of cadmium (Cd2+) toxicity, we
investigate Cd2+ effects on plant water losses, gas exchanges and stomatal behaviour in …

Iron, an essential nutrient, is not readily available to plants because of its low solubility. In
addition, iron is toxic in excess, catalyzing the formation of hydroxyl radicals that can …

We have characterized the human gene SLC39A4, which encodes a protein with features
characteristic of a ZIP zinc transporter. The chromosomal location and expression of …

Phytoremediation is a developing technology that can potentially address the problems of
contaminated agricultural land or more intensely polluted areas affected by urban or …

Abstract Uptake of Cd and Zn by intact seedlings of two contrasting ecotypes of the
hyperaccumulator Thlaspi caerulescens was characterized using radioactive tracers. Uptake …

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 mutants irt1‐1 and irt1‐2 of Arabidopsis thaliana were identified among a collection of T‐
DNA‐tagged lines on the basis of a decrease in the effective quantum yield of photosystem …
