Arsenic uptake and metabolism in arsenic resistant and nonresistant plant species (2002, background): “In addition, the intimate involvement of PC production in arsenate resistance of H. lanatus was demonstrated, as higher concentrations of PCs were produced in arsenate-resistant phenotypes, and their arsenic resistance was completely removed by the presence of the inhibitor BSO (Hartley-Whitaker et ”
Mechanisms of Plant Resistance to Metal and Metalloid Ions and Potential Biotechnological Applications (2005, background): “However, there is little evidence for any role of such enzymes in inducible tolerances; their role is constitutive (Hartley-Whitaker et al., 2001).”
Arsenic Uptake, Toxicity, Detoxification, and Speciation in Plants: Physiological, Biochemical, and Molecular Aspects (2018, background): “[288] found that under the same levels of As(V) stress, the tolerant clones of H.”
Influences of Arbuscular Mycorrhizal Fungus Glomus mosseae on Growth and Nutrition of Lentil Irrigated with Arsenic Contaminated Water (2006, background): “Reduced root length in response to arsenic exposure has been reported by a number of investigators (Hartley-Whitaker et al., 2001; Kaputska et al., 1995; Meharg and Macnair, 1992; Paliouris and Hutchinson, 1991; Pepper et al., 1988; Porter and Peterson, 1977; Sneller et al., 1999).”
Plant Responses to Heavy Metal Toxicity (2012, background): “Although an arsenate-tolerant genotype of Holcus lanatus absorbs less arsenate than an equivalent non-tolerant genotype (Meharg and Macnair 1992) due to the suppression of the high-affinity arsenate transport system combined with the constitutive synthesis of PCs (Hartley-Whitaker et al. 2001).”
Arsenic Toxicity: The Effects on Plant Metabolism (2012, background): “Alternatively, H2O2 can oxidize GSH and ascorbate through the action of specific peroxidases, or in the case of GSH, also through the action GRXs and GSH-S-transferases (GST).”
Arsenic uptake and toxicity in plants: integrating mycorrhizal influences (2010, background): “As(V) reduction can also result in formation of reactive oxygen species and lipid peroxidation, with consequent cellular damage (Geng et al. 2006; Gunes et al. 2009; Hartley-Whitaker et al. 2001; Mascher et al. 2002).”
Arsenate, arsenite and dimethyl arsinic acid (DMA) uptake and tolerance in maize (Zea mays L.) (2008, background): “Arsenate uptake and toxicity/ tolerance has been well characterised in plants (Hartley-Whitaker et al. 2001), with arsenate acting as a phosphate analogue with regards to membrane transport.”
Physiology and molecular biology of stress tolerance in plants (2006, background): “Arsenate tolerance in Holcus lanatus requires both adaptive suppression of a high-affinity phosphate uptake system and constitutive phytochelatin production (Hartley-Whitaker et al., 2001a,b).”
Molecular Mechanism of Heavy Metal Toxicity and Tolerance in Plants: Central Role of Glutathione in Detoxification of Reactive Oxygen Species and Methylglyoxal and in Heavy Metal Chelation (2012, background): “As induces a significant increase in GSH levels in As tolerant Holcus lanatus [266].”
Arsenic induced oxidative stress in plants (2012, background): “…in cellular membranes that increases the electrolyte leakage, amount of thiobarbituric acid-reacting substances (TBARS) and H2O2 content in plants like, Hol- cus lanatus (Hartley-Whitaker et al. 2001), red clover (Mascher et al. 2002), mung bean (Singh et al. 2007), and rice (Shri et al. 2009).”
