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 …

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

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 …

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 …

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

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 …

Rice cDNA and genomic libraries were screened in order to clone an Fe (II) transporter
gene. A cDNA clone highly homologous to the Arabidopsis Fe (II) transporter gene IRT1 was …

We have previously identified an ecotype of the hyperaccumulator Thlaspi caerulescens
(Ganges), which is far superior to other ecotypes (including Prayon) in Cd uptake. In this …

An ideal plant for environmental cleanup can be envisioned as one with high biomass
production, combined with superior capacity for pollutant tolerance, accumulation, and/or …
