Detoxification of arsenic by phytochelatins in plants.
As is a ubiquitous element present in the atmosphere as well as in the aquatic and terrestrial environments. Arsenite and arsenate are the major forms of As intoxication, and these anions are readily taken up by plants. Both anions efficiently induce the biosynthesis of phytochelatins (PCs) ([gamma-glutamate-cysteine](n)-glycine) in vivo and in vitro. The rapid induction of the metal-binding PC...
متن کاملPhytoremediation for Arsenic Contamination: Arsenate Reductase Phytoremediation for Arsenic Contamination: Arsenate Reductase
Arsenic is a toxic pollutant present in the environment that causes serious health issues. Phytoremediation is one potential solution to mitigate arsenic contamination in either soil or water. Two main forms of arsenic exist in the environment, arsenite, [As(III)], and arsenate, [As(V)]. In plant mechanisms, arsenate reductase reduces arsenate to arsenite with the help of thioredoxins or glutar...
متن کاملAquatic arsenic: phytoremediation using floating macrophytes.
Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...
متن کاملPhytoremediation of arsenic-contaminated groundwater by the arsenic hyperaccumulating fern Pteris vittata L.
Arsenic concentrations in a much larger fraction of U.S. groundwater sources will exceed the maximum contaminant limit when the new 10 microg L(-1) EPA standard for drinking water takes effect in 2006. Thus, it is important to develop remediation technologies that can meet this new standard. Phytoremediation of arsenic-contaminated groundwater is a relatively new idea. In this research, an arse...
متن کاملPhytoremediation of arsenic contaminated paddy soils with Pteris vittata markedly reduces arsenic uptake by rice.
Arsenic (As) accumulation in food crops such as rice is of major concern. To investigate whether phytoremediation can reduce As uptake by rice, the As hyperaccumulator Pteris vittata was grown in five contaminated paddy soils in a pot experiment. Over a 9-month period P. vittata removed 3.5-11.4% of the total soil As, and decreased phosphate-extractable As and soil pore water As by 11-38% and 1...
