Copper toxicity in Prunus cerasifera: growth and antioxidant enzymes responses of in vitro grown plants (2005, background): “A complex metal homeostasis network system has evolved in plants to regulate heavy metal uptake and distribution, thus protecting the metabolic process [28,29].”
Heavy metal toxicity: cadmium permeates through calcium channels and disturbs the plant water status. (2002, background): “Some of these detoxification elements have been identified at molecular level (Clemens, 2001; Cobbett, 2000).”
Heavy metal accumulation and growth responses in poplar clones Eridano (Populus deltoides × maximowiczii) and I-214 (P. × euramericana) exposed to industrial waste (2004, background): “Independent from their biological function, both essential and non-essential heavy metals can be toxic above a certain threshold and plants have evolved a complex metal homeostasis network system, which regulates their uptake and distribution enabling an effective protection of the metabolic process”
Glycine betaine-induced lead toxicity tolerance related to elevated photosynthesis, antioxidant enzymes suppressed lead uptake and oxidative stress in cotton (2014, background): “It was found that heavy metals at higher concentrations inhibit germination of seed and plant growth and disturb many biochemical and physiological processes (Clemens, 2001; Farooq et al., 2013).”
Metal hyperaccumulation and bioremediation (2007, background): “…(Phyllanthus), Leucocroton and Asteraceae (Senecio, Pentacalia); Zn: Brassicaceae (Thlaspi); Cu and Co: Lamiaceae, Scrophulariaceae (Baker and Brooks 1989, Chaney et al. 1997, Brooks 1998, Clemens 2001, Broadhurst et al. 2004, Gratao et al. 2005, Prasad 2005, Vinterhalter and Vinterhalter 2005).”
Mechanisms of Plant Resistance to Metal and Metalloid Ions and Potential Biotechnological Applications (2005, background): “Resistance to non-essential elements, as for essential elements, must involve adaptation to normal physiological function (Clemens, 2001).”
Direct shoot regeneration from leaf explants of Jatropha curcas in response to thidiazuron and high copper contents in the medium (2010, background): “Copper is the component or activator of many enzymes involved in electron transport, protein and sugar (Purnhauser and Gyulai 1993) synthesis, is an essential cofactor of superoxide dismutase, cytochrome c oxidase, amino oxidase, laccase, plastocyanin and polyphenol oxidase (Clemens 2001).”
Chapter 4 Iron Dynamics in the Rhizosphere: Consequences for Plant Health and Nutrition (2008, background): “This iron homeostasis is achieved by complex iron trafficking networks that involve processes based on chelation and reduction mechanisms (Andrews et al., 2003; Briat and Lobréaux, 1997; Clemens, 2001).”
Heavy metal detoxification and tolerance mechanisms in plants: Implications for phytoremediation (2016, background): “…the heavy metal out of the cell or by sequestrating it into the vacuole, 528 thereby limiting the contact of heavy metals with the sensitive metabolic activities taking place 529 in the cytosol or other cellular compartments (DalCorso et al. 2008; Dalcorso et al. 2010; 530 Clemens 2001).”
Geographic cohesion, chromosomal evolution, parallel adaptive radiations, and consequent floral adaptations in Calochortus (Calochortaceae): evidence from a cpDNA phylogeny (2003, background): “Tolerance to heavy metals depends on the ability to prevent such cations from being absorbed in the first place, and/or the ability to sequester them successfully after root uptake (Fitter & Hay, 1987; Clemens, 2001; Assuncao et al., 2003a; Cobbett, 2003).”
Natural variation and QTL analysis for cationic mineral content in seeds of Arabidopsis thaliana (2004, background): “This is not surprising considering that maintaining cation homeostasis requires a network of metal uptake, transportation, trafficking and sequestration mechanisms, tightly controlled by several genes, which will not all be metal specific (Clemens 2001).”
Hemin-mediated alleviation of zinc, lead and chromium toxicity is associated with elevated photosynthesis, antioxidative capacity; suppressed metal uptake and oxidative stress in rice seedlings (2017, background): “So plants also have developed numerous ways to maintain cellular metal homeostasis (Clemens 2001), such as restricted metal uptake, active efflux, sequestration into vacuole and chelated by metal-binding peptide or proteins (Hall 2002; Verbruggen et al.”
Salicylic Acid Alleviates the Cadmium Toxicity in Barley Seedlings1 (2003, background): “Cd sequestration and chelation constitute the two principle mechanisms employed to avoid free Cd in plasmatic compartments and to tolerate exposure to elevated Cd levels in the soil (Clemens, 2001).”
The Genetic Basis of Metal Hyperaccumulation in Plants (2002, background): “There have been a number of recent reviews of the cellular basis of metal tolerance in plants that have discussed the range of ligands implicated in metal-ion homeostasis and detoxification (Zenk, 1996; Rauser, 1999; Meagher, 2000; Clemens, 2001; Clemens et al., 2002; Hall, 2002).”
