The accumulation of foliar anthocyanins can be consistently attributed to a small range of contexts. Foliar anthocyanin accumulates in young, expanding foliage, in autumnal foliage of deciduous species, in response to nutrient deficiency or ultraviolet (UV) radiation exposure, and in association with damage or defense against browsing herbivores or pathogenic fungal infection. A common thread through these causative factors is low photosynthetic capacity of foliage with accumulated anthocyanin relative to leaves at different ontogenetic stages or unaffected by the environmental factor in question.The ecophysiological function of anthocyanin has been hypothesized as: 1) a compatible solute contributing to osmotic adjustment to drought and frost stress; 2) an antioxidant; 3) a UV protectant; and 4) protection from visible light. Review of the internal leaf distribution of anthocyanin, of experimental evidence using seedlings, and of studies that directly investigated light absorption by anthocyanin and its development relative to recognized processes of photoprotection support the hypothesis that anthocyanins provide protection from visible light.

Role of Anthocyanins in Plant Defence (2008, background): “There is very good evidence for physiological benefits of autumn leaf colouration, such as an enhanced recovery of foliar nitrogen owing to the protection of degrading chloroplasts by anthocyanins from the effects of photooxidation (Hoch et al. 2001; Yamasaki 1997; Chalker-Scott 1999; Matile 2000; H”
Multiple functional roles of anthocyanins in plant-environment interactions. (2015, background): “Because anthocyanins occur so commonly across disparate vegetative organs, there has been concerted research effort to understand their functional significance, particularly in plants that experience abiotic stressors (Chalker-Scott 1999; Hoch et al., 2001; Steyn et al., 2002; Close and Beadle 2003;”
Retrieval of foliar information about plant pigment systems from high resolution spectroscopy (2009, background): “Like carotenoids, anthocyanins protect the photosynthetic system from excess light, particularly excess UV radiation (Merzlyak and Chivkunova, 2000; Gitelson et al., 2001), and may provide other functions, e.g., protection from herbivory and fungal pathogens (Close & Beadle, 2003).”
Optimizing spectral indices and chemometric analysis of leaf chemical properties using radiative transfer modeling (2011, background): “…a and b enable light harvesting for photosynthesis (Anderson, 1986; Lichtenthaler et al., 1981), while carotenoids (carotenes and xanthophylls) and anthocyanins afford protection from excess light, for example during leaf development or abiotic stress (Close and Beadle, 2003; Gould et al., 2008).”
Sucrose signaling pathways leading to fructan and anthocyanin accumulation: A dual function in abiotic and biotic stress responses? (2014, background): “Roles for anthocyanins in 3 herbivore protection have been suggested (Close and Beadle, 2003; Cooney et al., 2012), 4 but more experimental verification is necessary.”
Nondestructive Estimation of Anthocyanin Content in Grapevine Leaves (2009, background): “The pigment, which is localized in vacuoles of epidermal cells, serves as a filter: an internal light trap for excessive solar radiation (Chalker-Scott 1999, Close and Beadle 2003, Steyn et al. 2002).”
Aposematic (Warning) Coloration in Plants (2009, neutral): “…aerial plant other than green may in many cases (but certainly not all, see Chalker-Scott 1999 ; Matile 2000 ; Hoch et al. 2001, 2003 ; Lee and Gould 2002 ; Gould et al. 2002a, b ; Close and Beadle 2003 ; Gould 2004 ; Ougham et al. 2005 ; Hatier and Gould 2008) be linked to lower photosynthesis.”
What do red and yellow autumn leaves signal? (2007, positive): “…to the protection by anthocyanins from photoinhibition and photo-oxidation (Yamasaki, 1997; Chalker-Scott, 1999; Matile, 2000; Feild et al., 2001; Gould et al., 2002a; Lee & Gould, 2002a; Hoch et al., 2001, 2003; Close & Beadle, 2003; Schaefer & Wilkinson, 2004; Gould, 2004; Ougham et al., 2005).”
Hyperspectral remote sensing of plant pigments. (2006, background): “Anths can modify the light environment within a leaf and have the potential to regulate photosynthesis and limit photoinhibition and photobleaching (Barker et al., 1997) thereby having a photoprotective function (Steyn et al., 2002; Close and Beadle, 2003).”
Anthocyanin Function in Vegetative Organs (2008, background): “Reflecting the resurgence of scientific interest in anthocyanin (and betalain) function in vegetative organs, several reviews have been written on this topic in recent years (Chalker-Scott 1999, 2002; Hoch et al. 2001; Gould et al. 2002b; Lee and Gould 2002a, 2002b; Steyn et al. 2002; Close and Bea”
