Initial Steps of Copper Detoxification: Outside and Inside of the Plant Cell,ess in ambient medium is presented. Copper (Cu) is most toxic heavy metal, which trace amounts are required to sustain plant life (so-called essential elements), but its high concentrations cause plant death. In plants, copper occurs in reduced (Cu.) and oxidized (Cu.) states, and also as nanopartic

Transport, Accumulation, and Physiological Effects of Vanadium,ompounds will be oxidized to vanadate(V), which is soluble and thus drains into the ground water. Since vanadate(V) acts as a phosphate antagonist, it is potentially toxic. Soil bacteria such as . and . reduce vanadate to insoluble and comparatively harmless vanadium(IV) hydroxide. The remobilizatio

Microbial Remediation of Arsenic Contaminated Soil,erefore, remediation of arsenic contaminated soil is extremely important. Bioremediation with special reference to microbial approaches hold promise to clean up the legacy of arsenic contaminated soils. Among microbial approaches, oxidation, reduction, and biomethylation are the major transformation

Fate of Cadmium in Calcareous Soils under Salinity Conditions,toxic than other heavy metals and consequently imposing harmful effects on human and other animals by entering food chain. This article reviews recent papers showing the behavior of Cd in calcareous soils specially under the salinity conditions. First, the chemistry of calcareous and saline soils is

Organellar Proteomics: A High-Throughput Approach for better Understanding of Heavy Metal Accumulats, wherein the cell wall, plasma membrane, cytosol, and vacuoles play vital roles. Identification of the proteins involved in these organ-specific heavy metal response pathways is a fundamental step in the process of understanding the molecular mechanisms leading to accumulation and detoxification o

Sulfur Metabolism as a Support System for Plant Heavy Metal Tolerance,stresses. Metabolically, sulfur metabolism is a core pathway for the synthesis of molecules required for heavy metal tolerance in plants. This chapter provides an overview of sulfur metabolism in plants, how it plays a critical role in heavy metal tolerance, and how efforts to engineer these pathway

Cd(II)-Activated Synthesis of Phytochelatins, algae, and a fungal species. Synthesis of the peptides is mediated by an enzyme designated as PC synthase (PCS) from the tripeptide glutathione (GSH). Point mutation of the . PCS demonstrated a catalytic triad of the protein, with the Cys56 thiol group as the acylation site. A peptide elongation re
