IRT1 and IRT2 are members of the Arabidopsis ZIP metal transporter family that are
specifically induced by iron deprivation in roots and act as heterologous suppressors of …

The ZIP superfamily of transporters plays important roles in metal ion uptake in diverse
organisms. There are 12 ZIP-encoding genes in humans, and we hypothesize that many of …

Zinc (Zn) is an essential micronutrient with numerous cellular functions in plants, and its
deficiency represents one of the most serious problems in human nutrition worldwide. Zn …

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 micronutrient zinc is essential for all living organisms, but it is toxic at high
concentrations. Here, to understand the effects of excess zinc on plant cells, we performed …

The metabolism of sulphur in angiosperms is reviewed under the aspect of exposure to
ecologically relevant concentrations of sulphur, heavy metals and metalloids. Because of the …

Iron acquisition in Arabidopsis depends mainly on AtIRT1, a Fe 2+ transporter in the plasma
membrane of root cells. However, substrate specificity of AtIRT1 is low, leading to an excess …

Metals contaminate the soil when present in high concentrations causing soil and ultimately
environmental pollution.“Phytoremediation” is the use of plants to remove pollutants from …

Plants strictly regulate the uptake and distribution of Zn, which is essential for plant growth
and development. Here, we show that Arabidopsis thaliana PCR2 is essential for Zn …

The review considers the roles of root and shoot tissues in transport and accumulation of
heavy metals in plants of two contrast groups, ie, excluders and hyperaccumulators. The …
