We are just beginning to understand the metabolism of heavy metals and to use their
metabolic functions in biotechnology, although heavy metals comprise the major part of the …

Zinc is an essential micronutrient. Genes responsible for zinc uptake have now been
identified from yeast and plants. These genes belong to an extended family of cation …

The molecular basis for the transport of manganese across membranes in plant cells is
poorly understood. We have found that IRT1, an Arabidopsis thaliana metal ion transporter …

We describe the isolation of an Arabidopsis gene that is closely related to the animal ZnT
genes (Zn t ransporter). The protein encoded by the ZAT (Z n transporter of A rabidopsis t …

Cellular functions require adequate homeostasis of several divalent metal cations, including
Mg 2+ and Zn 2+. Mg 2+, the most abundant free divalent cytoplasmic cation, is essential for …

The glandular epithelial cells of the human prostate gland have the unique capability and
function of accumulating the highest zinc levels of any soft tissue in the body. Zinc …

Most plants and animals depend on soil, as a growth substrate, for their sustained growth
and development. In many instances the sustenance of life in the soil matrix is adversely …

Many heavy metals are essential for plants and animals when present in the growing
medium in low concentrations (micronutrients: Cu, Zn, Fe, Mn, Mo, Ni, and Co); they become …

Despite the importance of metal ions in several catalytic functions, there has been, until
recently, little molecular information available on the mechanisms whereby metal ions are …

Reclamation of metalliferous areas is a priority field of biogeochemistry of trace elements.
Ultramafic outcrops rich in heavy metals have been mapped in different parts of the world …
