Phytoremediation is an economically viable green technology that utilizes hyperaccumulator
plants to remove heavy metals (HM) from the soil. Hyperaccumulators are adept at …

Phytochelatins (PCs) are small cysteine-rich peptides capable of binding metal (loid) s via
SH-groups. Although the biosynthesis of PCs can be induced in vivo by various metal (loid) …

Arsenic (As) polluted food chain has become a serious issue for the growth and
development of humans, animals and plants. Nitric oxide (NO) or silicon (Si) may mitigate As …

The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up
by the cells of the plant root. Once in the cell, AsV can be readily converted to AsIII, the more …

The contamination of the environment with toxic metals has become a worldwide problem.
Metal toxicity affects crop yields, soil biomass and fertility. Soils polluted with heavy metals …

Heavy metals such as Cu and Zn are essential for normal plant growth, although elevated
concentrations of both essential and non‐essential metals can result in growth inhibition and …

Over the past 200 years emissions of toxic heavy metals have risen tremendously and
significantly exceed those from natural sources for practically all metals. Uptake and …

Arsenic (As) is an element that is nonessential for and toxic to plants. Arsenic contamination
in the environment occurs in many regions, and, depending on environmental factors, its …

Plants exposed to heavy metals accumulate an array of metabolites, some to high millimolar
concentrations. This review deals with N-containing metabolites frequently preferentially …

Elevation of arsenic levels in soils causes considerable concern with respect to plant uptake
and subsequent entry into wildlife and human food chains. Arsenic speciation in the …
