Molecular mechanisms of metal hyperaccumulation in plants [PDF]
New Phytologist, 2009 SummaryMetal hyperaccumulator plants accumulate and detoxify extraordinarily high concentrations of metal ions in their shoots. Metal hyperaccumulation is a fascinating phenomenon, which has interested scientists for over a century. Hyperaccumulators constitute an exceptional biological material for understanding mechanisms regulating plant metal ...

Waste Sedum plumbizincicola, a zinc (Zn) hyperaccumulator during phytoremediation, was recycled via a subcritical hydrothermal liquefaction (HTL) reaction into multiple streams of products, including hydrochar, bio-oil, and carboxylic acids. Results show approximately 90% of Zn was released from the S. plumbizincicola biomass during HTL at an optimized

Society has long recognised that certain plant species can infer the existence of minerals in the underlying soil but only in the later years of the 20th century was the ability of some plants to accumulate heavy metals reliably quantified. The term hyperaccumulation was introduced to describe such plants.

Hyperaccumulation: A Phytoremedial Approach
2010The prime requisite of agriculture is soil which serves as a reservoir of nutrients and water for the crops. Unfortunately, all the soil available on this planet is not arable, fertile, and it remains agriculturally unproductive. Land is mainly contaminated with heavy metals like Zn, Pb, Cr, Ni, and Cd.

Processing of Hyperaccumulator Plants to Nickel Products
2020Hyperaccumulator plants may contain valuable metals at concentrations comparable to conventional ore and can be significantly upgraded by incineration. There is an incentive to recover these metals as products in order to counterbalance the cost of disposing the contaminated biomass from contaminated soils, mine tailings, and processing wastes.

Metal ion ligands in hyperaccumulating plants
JBIC Journal of Biological Inorganic Chemistry, 2005Metal-hyperaccumulating plants have the ability to take up extraordinary quantities of certain metal ions without succumbing to toxic effects. Most hyperaccumulators select for particular metals but the mechanisms of selection are not understood at the molecular level. While there are many metal-binding biomolecules, this review focuses only on ligands

Facultative hyperaccumulation of heavy metals and metalloids
Plant Science, 2014Approximately 500 species of plants are known to hyperaccumulate heavy metals and metalloids. The majority are obligate metallophytes, species that are restricted to metalliferous soils. However, a smaller but increasing list of plants are "facultative hyperaccumulators" that hyperaccumulate heavy metals when occurring on metalliferous soils, yet also ...

Phytoremediation and hyperaccumulator plants
2005Phytoremediation is a group of technologies that use plants to reduce, remove, degrade, or immobilize environmental toxins, primarily those of anthropogenic origin, with the aim of restoring area sites to a condition useable for private or public applications.

Prospecting for hyperaccumulators of trace elements: a review
Critical Reviews in Biotechnology, 2014Specific plant species that can take up and accumulate abnormally high concentrations of elements in their aboveground tissues are referred to as "hyperaccumulators". The use of this term is justified in the case of enormous element-binding capacity of plants growing in their natural habitats and showing no toxicity symptoms.

Global Distribution and Ecology of Hyperaccumulator Plants
2017A large body of analytical data is available on the inorganic composition of many thousands of plant species, for which typical concentration ranges have been tabulated for major, minor, and trace elements. These elements include those that have been shown essential for plant growth, as well as others that lack this status, at least universally ...
