Hyperspectral remote sensing of plant pigments. (2006, background): “Anths may act as osmotic adjusters offering plants resistance to freezing and drought stress (Chalker-Scott, 1999) and there is evidence that Anths have antioxidant properties that aid recovery after foliar injury (Gould et al., 2002).”
Repair of DNA Damage Induced by Solar UV (2004, background): “Walbot 2003) and antioxidants (Gould et al. 2002), but also as absorbers of visible light.”
Sucrose-Specific Induction of Anthocyanin Biosynthesis in Arabidopsis Requires the MYB75/PAP1 Gene1 (2005, background): “Anthocyanins are also important antioxidantmolecules (Gould et al., 2002) and help to protect plants from damage by active oxygen species (Nagata et al., 2003).”
Membrane transport of hydrogen peroxide. (2006, background): “In contrast, green leaves only slowly decrease H2O2 levels [83].”
Significance of Flavonoids in Plant Resistance and Enhancement of Their Biosynthesis (2005, unknown): “It is assumed by several authors that flavonoids may also provide antioxidant functions in response to excess light (Gould et al., 2002; Rozema et al., 2002; Tattini et al., 2004).”
Anthocyanin Function in Vegetative Organs (2008, background): “Irrespective of their intracellular location, however, anthocyanin-containing leaf cells have been observed under the microscope to remove H2O2 more swiftly than acyanic cells ( Gould et al. 2002a ).”
Reactive oxygen species as signals that modulate plant stress responses and programmed cell death (2006, background): “They also contain high levels of ascorbate, glutathione and peroxidases localized at the tonoplast inner surface.((26))”
Anthocyanin Biosynthesis and Degradation Mechanisms in Solanaceous Vegetables: A Review (2018, background): “Wounded anthocyanin-rich leaf tissue showed faster recovery from oxidative stress caused by mecha nical injury (Gould et al., 2002).”
Proteome analysis of soybean roots subjected to short-term drought stress (2010, unknown): “Anthocyanin could serve as an antioxidant (Gould et al. 2002).”
Betacyanin synthesis in red beet (Beta vulgaris) leaves induced by wounding and bacterial infiltration is preceded by an oxidative burst (2004, background): “Furthermore, leaf epidermis regions enriched with anthocyanins have an elevated antioxidant capacity to scavenge the H2O2 produced in the mesophyll tissue after mechanical injury [12].”
Screening of visible and UV radiation as a photoprotective mechanism in plants (2008, background): “In vast majority of studied systems, the synthesis of Phe is controlled by up-regulation of the key enzymes of the phenylpropanoid pathway, such as phenylalanine ammonia-lyase (PAL) or chalcone synthase (CHS) [1, 74, 108].”
Stress Protective Role of Secondary Metabolites Diversity of Functions and Mechanisms (2008, unknown): “Recently, an increasing amount of evidences substantiates the functioning of secondary metabolites as antioxidants and antiradicals, assisting the plants to cope with oxidative stress arising in hostile environments (Grace and Logan, 2000; Grassmann et al., 2002; Gould et al., 2002).”
Drought and Salinity Stress Responses and Microbe-Induced Tolerance in Plants (2020, background): “Additionally, the protection of anthocyanins over chlorophylls also contributes to plant photoprotection (Gould et al., 2002).”
