Remediation of sites contaminated with toxic metals is particularly challenging. Unlike
organic compounds, metals cannot be degraded, and the cleanup usually requires their …

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 …

The world population is expanding rapidly and will likely be 10 billion by the year 2050.
Limited availability of additional arable land and water resources, and the declining trend 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 …

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 …

Plant foods can serve as dietary sources of all essential minerals required by humans.
Unfortunately, mineral concentrations are low in some plants, especially many staple food …

Escherichia coli zupT (ygiE), encoding a ZIP family member, mediated zinc uptake. Growth
of cells disrupted in both zupT and the znuABC operon was inhibited by EDTA at a much …

The importance of zinc in organisms is clearly established, and mechanisms involved in zinc
acquisition by plants have recently received increased interest. In this report, the …
