In the course of evolution, plants adapted to widely differing metal availabilities in soils and
therefore represent an important source of natural variation of metal homeostasis networks …

Transition metal transporters are of central importance in the plant metal homeostasis
network which maintains internal metal concentrations within physiological limits. An …

Understanding of molecular mechanisms of heavy metal (HM) tolerance is an important
issue in plant biology because HM contamination has become a potential risk for modern …

Plants need many different metal elements for growth, development and reproduction, which
must be mobilized from the soil matrix and absorbed by the roots as metal ions. Once taken …

Heavy metal homeostasis is maintained in plant cells by specialized transporters which
compartmentalize or efflux metal ions, maintaining cytosolic concentrations within a narrow …

HMA2, HMA4, and HMA7 are three of the eight heavy metal transporting P1B-type ATPases
in the simple plant Arabidopsis thaliana. The first two transport Zn2+, and the third transports …

Metal-hyperaccumulating plants have the ability to take up extraordinary quantities of certain
metal ions without succumbing to toxic effects. Most hyperaccumulators select for particular …

Agricultural soils are under threat of toxic metal/metalloid contamination from anthropogenic
activities, leading to excessive accumulation of arsenic (As), cadmium (Cd), lead (Pb), and …

Soil contamination by heavy metals and metalloids such as cadmium (Cd) and arsenic (As)
poses a major threat to the environment and to human health. Vacuolar sequestration is one …

Environmental pollution is one of the major problems for human health. Toxic heavy metals
are normally present as soil constituents or can also be spread out in the environment by …
