AbstractMain conclusionAnthocyanins in upper (adaxial) leaf tissues provide greater photoprotection than in lower (abaxial) tissues, but also predispose tissues to increased shade acclimation and, consequently, reduced photosynthetic capacity. Abaxial anthocyanins may be a compromise between these costs/benefits. Plants adapted to shaded understory environments often exhibit red/purple anthocyanin pigmentation in lower (abaxial) leaf surfaces, but rarely in upper (adaxial) surfaces. The… Expand
Variegation and red abaxial epidermis define the leaf optical properties of Cyclamen purpurascens
TLDR
The data reveal the importance of these pigments in leaf variegation, and particularly of the red abaxial anthocyanic epidermis for absorbing light in the green, yellow and near infrared. Expand

TLDR
The results suggest that the Excoecaria leaves accumulate a distinct group of phenolic metabolites, mainly GGs/ETs, at the abaxial layer, which prevent anthocyanin degradation and increase the pigment stability, and consequently lead to the permanent maintenance of the red leaves. Expand
Photosynthetic activity and photoprotection in green and red leaves of the seagrasses, Halophila ovalis and Cymodocea rotundata: implications for the photoprotective role of anthocyanin
TLDR
Although anthocyanin appears to contribute to photoprotection by acting as sunscreen, it does not confer greater tolerance to high irradiance in H. rotundata and Anthocyanic seagrasses, which cope equally well with high light in their natural settings by utilizing different combinations of photoprotsective mechanisms.

Multiple Consequences Induced by Epidermally-Located Anthocyanins in Young, Mature and Senescent Leaves of Prunus
TLDR
It is proposed that epidermally-located anthocyanins may be principally synthetized to maintain an efficient carbon-sink strength in young and senescent leaves, thus extending the RLP leaf lifespan. Expand
Aggravation of photoinhibition during variegated leaf development in Actinidia kolomikta (Rupr. & Maxim.) Maxim.
Abstract Variegated leaves of Actinidia kolomikta (Rupr. & Maxim.) Maxim. are white, pink and pale green according to the order of leaf development, respectively. However, the pale-green leaves areExpand
Relationship between leaf reddening, ROS and antioxidants in Buxus microphylla during overwintering
TLDR
The results suggested that H2O2 might play an important role in the winter reddening of sun leaves by promoting the accumulation of carotenoids. Expand
Delayed greening in phosphorus-efficient Hakea prostrata (Proteaceae) is a photoprotective and nutrient-saving strategy.
Hakea prostrata R.Br. (Proteaceae) shows a 'delayed greening' strategy of leaf development characterised by reddish young leaves that become green as they mature. This trait may contribute toExpand
Can anthocyanin presence ameliorate the photosynthetic performance of Prunus saplings subjected to polyethylene glycol-simulated water stress?
The aim was the evaluation of the biochemical and physiological responses of green- (GP) and red-leafed (RP) Prunus cerasifera mature leaves to 20 d of polyethylene glycol (PEG 6000)-induced waterExpand
The same anthocyanins served four different ways: Insights into anthocyanin structure-function relationships from the wintergreen orchid, Tipularia discolor.
TLDR
The results showed that the same three cyanidin 3,7,3'-triglucosides, in similar concentrations and proportions, accounted for coloration in each of these cases, and served as a reminder that plants may employ the same anthocyanins in different anatomical locations to achieve a broad range of colors.

When are foliar anthocyanins useful to plants? Re-evaluation of the photoprotection hypothesis using Arabidopsis thaliana mutants that differ in anthocyanin accumulation
Abstract There is strong empirical evidence that foliar anthocyanins assist in protecting chloroplasts from potentially damaging effects of supernumerary photons. Nevertheless, around 30% ofExpand

Optical effects of abaxial anthocyanin on absorption of red wavelengths by understorey species: revisiting the back-scatter hypothesis
TLDR
The results suggest that abaxial anthocyanins do not significantly enhance the absorption of red light in the species tested, and alternative functions are discussed. Expand
Leaf morphological and physiological adjustments to the spectrally selective shade imposed by anthocyanins in Prunus cerasifera.
TLDR
Red leaves were thinner and had a lower stomatal frequency, area- based CO2 assimilation rate, apparent carboxylation efficiency and chlorophyll a:b ratio than green leaves, however, red leaves were similar to green leaves in conductivity to water vapor diffusion, dry-mass-based chlorophyLL concentrations and carotenoid:chlorophyll ratios. Expand
Exposed red (anthocyanic) leaves of Quercus coccifera display shade characteristics.
TLDR
Photosynthetic and photoprotective characteristics were compared in young green and red leaves of the same age, sampled from the corresponding phenotypes occupying the same habitat and confirm the light acclimation hypothesis and are also compatible with a photoprotsective function of anthocyanins.

Abaxial Anthocyanin Layer in Leaves of Tropical Rain Forest Plants: Enhancer of Light Capture in Deep Shade
TLDR
Observations on four Indo-malesian forest species polymorphic provide empirical evidence that the cyanic layer can improve photosynthetic energy capture by back-scattering additional light through the photosynthesis tissue. Expand
Responses to low phosphorus in high and low foliar anthocyanin coleus (Solenostemon scutellarioides) and maize (Zea mays).
TLDR
It could not be concluded that high foliar anthocyanin production confers a general functional advantage under low-P stress, and more research comparing inducible vs constitutive production may help elucidate the role of anthOCyanin biosynthesis in P deficiency responses. Expand
Functional role of anthocyanins in high-light winter leaves of the evergreen herb Galax urceolata.
TLDR
Results suggest that anthocyanins function as light attenuators and may also contribute to the antioxidant pool in winter leaves and may be necessary for their photo-induction. Expand
Seasonal photosynthesis and anthocyanin production in 10 broadleaf evergreen species.
TLDR
It is concluded that anthocyanin production during winter is likely not associated with diminished photosynthetic capacity, and may simply represent an alternative photoprotective strategy utilised by some species during winter. Expand
The importance of being red when young: anthocyanins and the protection of young leaves of Quercus coccifera from insect herbivory and excess light.
TLDR
It is suggested that the importance of a photoprotective anthocyanic screen is low in thin, young leaves with low chlorophyll concentrations because the green light attenuated by Anthocyanins is less significant for chlorophyLL excitation. Expand
Coordination of anthocyanin decline and photosynthetic maturation in juvenile leaves of three deciduous tree species.
TLDR
Results suggest that Anthocyanin reassimilation is linked closely with chloroplast and whole-leaf developmental processes, supporting the idea that anthocyanins protect tissues until light processing and carbon fixation have matured to balance energy capture with utilization. Expand
The ecophysiology of foliar anthocyanin
TLDR
Review of the internal leaf distribution of anthocyanin, of experimental evidence using seedlings, and of studies that directly investigated light absorption by anthocynin and its development relative to recognized processes of photoprotection support the hypothesis that anthocianins provide protection from visible light.
