Zinc (Zn) is an essential element for the normal growth of plants but information is scarce on
the mechanisms whereby Zn is transported in rice (Oryza sativa L.) plants. Four distinct …

SLC39 proteins are members of the broader ZIP family of metal ion transporters found in
organisms at all phylogenetic levels. Most ZIP transporters have eight predicted …

Zinc (Zn) is an essential micronutrient for plants, playing catalytic or structural roles in
enzymes, transcription factors, ribosomes, and membranes. In humans, Zn deficiency is the …

Cadmium (Cd) is a widespread, naturally occurring element present in soil, rock, water,
plants and animals. Cd is a non‐essential element for plants and is toxic at higher …

Uptake, translocation, detoxification, and sequestration of heavy metals (HMs) are key
processes in plants to deal with excess amounts of HM. Under natural conditions, plant roots …

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 …

ZIP transporters (ZRT, IRT‐like proteins) are involved in the transport of iron (Fe), zinc (Zn)
and other divalent metal cations. The expression of IRT3, a ZIP transporter, is higher in the …

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 …

NRAMP (natural resistance-associated macrophage protein) homologues are evolutionarily
conserved bivalent metal transporters. In Arabidopsis, AtNRAMP3 and AtNRAMP4 play a …
