• Polyamines reduce salt-induced oxidative damage by increasing the activities of antioxidant enzymes and decreasing lipid peroxidation in Virginia pine (2005, methodology): “The polyamines (putrescine, spermidine, and spermine) are found in a wide range of organisms from bacteria to plants and animals (Walters 2000; Groppa et al. 2001; Cowley and Walters 2002).”
• Polyamines and abiotic stress: recent advances (2007, background): “adverse conditions, though their precise role as antioxidants is still a matter of debate (Groppa et al., 2001; Chattopadhayay et al., 2002; Kakkar and Sawhney, 2003).”
• Polyamines: potent modulators of plant responses to stress (2013, background): “However, Groppa et al. (2001) reported that Cd2 or Cu2 at 0.5 mM reduced Put content in sunflower leaf discs using the same experimental design due to decreased ADC and ODC activities, even though DAO activity was significantly reduced.”
• Cadmium-induced oxidative damage in rice leaves is reduced by polyamines (2007, background): “Grop- pa et al. (2001) also demonstrated that Spm and Spd were effective in reducing Cd-caused lipid peroxidation in sunflower leaf discs.”
• Overexpression of spermidine synthase enhances tolerance to multiple environmental stresses and up-regulates the expression of various stress-regulated genes in transgenic Arabidopsis thaliana. (2004, background): “On the other hand, polyamines have ROSscavenging and membrane-protecting properties (Roberts et al. 1986, Løvaas 1991, Groppa et al. 2001).”
• Polyamine Function in Plants: Metabolism, Regulation on Development, and Roles in Abiotic Stress Responses (2019, background): “Under cadmium- and copper-induced oxidative stress, lipid peroxidation in sunflower leaf discs increased, while the activities of glutathione reductase (GR) and superoxide dismutase (SOD) decreased (Groppa et al., 2001).”
• Cadmium toxicity in plants (2005, background): “In Helianthus annuus leaves, Cd decreased GSH content, and decreased or increased the activity of the antioxidative enzymes SOD, CAT, APOX, GR and DHAR, depending on Cd concentration, the organ used and the age of the plants (Gallego et al., 1996, 1999; Groppa et al., 2001).”
