TOLERANCE OF HEAVY METALS IN VASCULAR PLANTS ARSENIC
of infections in plants, animals, and humans. Metal Tolerance Mechanisms In high concentrations, heavy metal ions react to form toxic compounds in cells (Nies, 1999). To have a toxic ef-fect, however, heavy metal ions must first enter the cell. Because some heavy metals are necessary for enzymatic functions and bacterial growth, uptake mechanisms exist that allow for the entrance of metal ions... Metal toxicity is an important factor limiting the growth of plants in many environments. Some metals, such as copper and zinc, are micronutrients at low concentrations and become toxic at higher levels, whereas others (e.g. aluminium and lead) are

The metal tolerance profile of Thlaspi BMC Plant Biology
Heavy metals are naturally occurring in the earth‘s crust but anthropogenic and industrial activities have led to drastic environmental pollutions in distinct areas. Plants are able to colonize such sites due to several mechanisms of heavy metal tolerance. Understanding of these pathways enables... aspects: metal tolerance in trees, heavy metal uptake by trees grown on contaminated substrates, heavy metal compartmentalisation within trees, phytoremediation using trees and the phytoremediation potential of willow (Salix spp.).

METAL TOLERANCE BAKER - 1987 - New Phytologist - Wiley
A tremendous research effort has focused on understanding how a rare set of naturally salt tolerant plants, halophytes, are able to cope with soil salinity, as a model for producing salt tolerant crops. One largely unexplored area of research is the evolution of salt...
