Hyperaccumulator - Wikipedia
A hyperaccumulator is a plant capable of growing in soil or water with high concentrations of metals, absorbing these metals through their roots, and concentrating extremely high levels of metals in their tissues. [1][2] The metals are concentrated at levels that are toxic to closely related species not adapted to growing on the metalliferous so...
List of hyperaccumulators - Wikipedia
This article covers known hyperaccumulators, accumulators or species tolerant to the following: Aluminium (Al), Silver (Ag), Arsenic (As), Beryllium (Be), Chromium (Cr), Copper (Cu), Manganese (Mn), Mercury (Hg), Molybdenum (Mo), Naphthalene, Lead …
Heavy metal hyperaccumulating plants: How and why do they do …
2011年2月1日 · Three basic hallmarks distinguish hyperaccumulators from related non-hyperaccumulating taxa: a strongly enhanced rate of heavy metal uptake, a faster root-to-shoot translocation and a greater ability to detoxify and sequester heavy metals in leaves.
Hyperaccumulator - an overview | ScienceDirect Topics
Hyperaccumulators are plants which in quantities well above those contained in the soil or in neighboring nonaccumulating plants, can accumulate PTEs in their aboveground tissues. It is possible to define hyperaccumulators as a special and extreme case of a …
Natural Molecular Mechanisms of Plant Hyperaccumulation and ...
Most hyperaccumulators (90%), such as Alyssum discolour, Alyssum inflatum, Minuartia baldaccii, and Viola dukadjinica, are endemic plants found on serpentine soils (rich in Ni, Co, Cr, and Mn) [19,20]. However, hyperaccumulators can also be found …
A global database for plants that hyperaccumulate metal and …
2017年11月15日 · Hyperaccumulators are exceptional models for fundamental science to understand metal regulation including the physiology of metal uptake, transport and sequestration, as well as evolution and adaptation in extreme environments (Pollard et al., 2002; Krämer, 2010).
Hyperaccumulators of metal and metalloid trace elements
2012年5月22日 · Plants that accumulate metal and metalloid trace elements to extraordinarily high concentrations in their living biomass have inspired much research worldwide during the last decades. Hyperaccumulators have been recorded and experimentally confirmed for elements such as nickel, zinc, cadmium, manganese, arsenic and selenium.
Molecular mechanisms of metal hyperaccumulation in plants
2009年1月15日 · 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 homeostasis as well as plant adaptation to extreme metallic environments.
Hyperaccumulation - an overview | ScienceDirect Topics
Hyperaccumulation is defined as the process of uptake, translocation, and accumulation of the heavy metals at concentrations higher than the surroundings in different parts of the plant (Maestri et al., 2010). You might find these chapters and articles relevant to this topic. Naveen K. Singh, Rajeev P. Singh, in Plant Metal Interaction, 2016.
New database catalogues plants that soak up contamination
2017年11月21日 · Hyperaccumulators are unusual plants that can absorb much larger amounts of metal compounds in their leaves and stems than normal plants, and they are very useful for cleaning up contaminated...
