• Hydrogen sulfide alleviated chromium toxicity in wheat (2010, background): “For example, studies in green gram roots exposed to Cr6+ stress showed that superoxide dismutase (SOD) and ascorbate peroxidase (APX) activities increased to ameliorate Cr-induced oxidative damages (Shanker et al. 2004).”
• Antioxidant enzyme responses of plants to heavy metal stress (2012, background): “…of two molecules of H2O2, APX is present throughout the cell and has higher substrate affinity in the presence of ascorbic acid as a reductant (Shanker et al. 2004) 5.4 Copper It is seen that in C.tinctorius the stimulation of SOD activity along with CAT seemed to play a protective role…”
• Chromium toxicity in plants. (2005, background): “…interconversion of reduced and oxidised forms of glutathione to maintain redox status of the cell as well as to scavenge free radicals could have caused a decrease in GSH. Metal-binding peptides like metallothionein have been reported to have increased under Cr(VI) stress (Shanker et al., 2004b).”
• Chromium toxicity and tolerance in plants (2013, background): “In roots of 15-day-old green gram (V. radiata) exposed to 50 μM Cr, increase in lipid peroxidation was seen 5 h after Cr(VI)-treatment compared to after 12 h in Cr(III)-treated roots (Shanker et al. 2004a).”
• Modification of chromium (VI) phytotoxicity by exogenous gibberellic acid application in Pisum sativum (L.) seedlings (2011, background): “Moreover, decrease in ascorbate and glutathione levels may also be due to their increased oxidation for scavenging of ROS and/or prevention of their formation (Shanker et al. 2004; Pandey et al. 2009b).”
• Effects of exogenous hydrogen sulfide on the ascorbate and glutathione metabolism in wheat seedlings leaves under water stress (2011, methodology): “A molar coefficient of 6.2 mM-1 cm-1 was used for the caculation of enzyme activity (Shanker et al. 2004).”
