Patterns of evolutionary rate variation among genes of the anthocyanin biosynthetic pathway. (1/731)

The anthocyanin biosynthetic pathway is responsible for the production of anthocyanin pigments in plant tissues and shares a number of enzymes with other biochemical pathways. The six core structural genes of this pathway have been cloned and characterized in two taxonomically diverse plant species (maize and snapdragon). We have recently cloned these genes for a third species, the common morning glory, Ipomoea purpurea. This additional information provides an opportunity to examine patterns of evolution among genes within a single biochemical pathway. We report here that upstream genes in the anthocyanin pathway have evolved substantially more slowly than downstream genes and suggest that this difference in evolutionary rates may be explained by upstream genes being more constrained because they participate in several different biochemical pathways. In addition, regulatory genes associated with the anthocyanin pathway tend to evolve more rapidly than the structural genes they regulate, suggesting that adaptive evolution of flower color may be mediated more by regulatory than by structural genes. Finally, for individual anthocyanin genes, we found an absence of rate heterogeneity among three major angiosperm lineages. This rate constancy contrasts with an accelerated rate of evolution of three CHS-like genes in the Ipomoea lineage, indicating that these three genes have diverged without coordinated adjustment by other pathway genes.  (+info)

Molecular cloning and biochemical characterization of a novel anthocyanin 5-O-glucosyltransferase by mRNA differential display for plant forms regarding anthocyanin. (2/731)

UDP-glucose: anthocyanin 5-O-glucosyltransferase (5-GT) is responsible for the modification of anthocyanins to more stable molecules in complexes for co-pigmentation, supposedly resulting in a purple hue. The cDNA encoding 5-GT was isolated by a differential display applied to two different forms of anthocyanin production in Perilla frutescens var. crispa. Differential display was carried out for mRNA from the leaves of reddish-purple and green forms of P. frutescens, resulting in the isolation of five cDNA clones predominantly expressed in the red form. The cDNA encoded a polypeptide of 460 amino acids, exhibiting a low homology with the sequences of several glucosyltransferases including UDP-glucose: anthocyanidin 3-O-glucosyltransferase. By using this cDNA as the probe, we also isolated a homologous cDNA clone from a petal cDNA library of Verbena hybrida. To identify the biochemical function of the encoded proteins, these cDNAs were expressed in Saccharomyces cerevisiae cells. The recombinant proteins in the yeast extracts catalyzed the conversion of anthocyanidin 3-O-glucosides into the corresponding anthocyanidin 3,5-di-O-glucosides using UDP-glucose as a cofactor, indicating the identity of the cDNAs encoding 5-GT. Several biochemical properties (optimum pH, Km values, and sensitivity to inhibitors) were similar to those reported previously for 5-GTs. Southern blot analysis indicated the presence of two copies of 5-GT genes in the genome of both red and green forms of P. frutescens. The mRNA accumulation of the 5-GT gene was detected in the leaves of the red form but not in those of the green form and was induced by illumination of light, as observed for other structural genes for anthocyanin biosynthesis in P. frutescens.  (+info)

Regulation of mitochondrial KATP channel by redox agents. (3/731)

The ATP-dependent K+ channel (KATP) was purified from the inner mitochondrial membrane and reconstituted into lipid bilayer membranes. KATP activity was inhibited by high concentrations of ATP and ADP, but activated by low concentrations (up to 200 microM) of ADP. p-Diethylaminoethylbenzoate (DEB) acted as a KATP opener: at micromolar concentrations, it reversed inhibition by ATP and ADP and it also prevented KATP rundown. Pelargonidine, extracted from flowers of Pelargonium, reduced spontaneous activity of KATP channels and diminished their potentiation by DEB. Their opposite action on KATP corresponded with their opposite redox properties in reactions with free radicals: DEB behaved as an electron donor, whereas pelargonidine acted as an electron acceptor. We hypothesize that thiol groups on mitoKATP are targets for redox-active ligans.  (+info)

Antimutagenicity of sweetpotato (Ipomoea batatas) roots. (4/731)

Antimutagenicity of the water extracts prepared from the storage roots of four varieties of sweetpotato with different flesh colors was investigated using Salmonella typhimurium TA 98. The extract from the whole roots of the purple-colored Ayamurasaki variety effectively decreased the reverse mutation induced not only by Trp-P-1, Trp-P-2, IQ, B[a]P, and 4-NQO but also by dimethyl sulfoxide extracts of grilled beef. Comparison of the inhibitory activity of the extracts from the normal Ayamurasaki and its anthocyanin-deficient mutant one suggested that the anthocyanin pigment in the flesh decreases the mutagenic activity of the mutagens as heterocyclic amines. Two anthocyanin pigments purified from purple-colored sweet-potato, 3-(6,6'-caffeylferulylsophoroside)-5-glucoside of cyanidin (YGM-3) and peonidin (YGM-6) effectively inhibited the reverse mutation induced by heterocyclic amines, Trp-P-1, Trp-P-2, and IQ in the presence of rat liver microsomal activation systems.  (+info)

Absorption and metabolism of cyanidin 3-O-beta-D-glucoside in rats. (5/731)

We have clarified for the first time how cyanidin 3-O-beta-D-glucoside (C3G), which is a potent antioxidant anthocyanin, is absorbed and metabolized in vivo. Rats were orally administered C3G (0.9 mmol/kg body weight), and C3G rapidly appeared in the plasma. However, the aglycon of C3G (cyanidin; Cy) was not detected, although it was present in the jejunum. Protocatechuic acid (PC), which may be produced by degradation of Cy, was present in the plasma and the concentration was 8-fold higher than that of C3G. These results suggest that plasma PC and C3G may contribute to the antioxidant activity of the plasma. In the liver and kidney, C3G was metabolized to methylated C3G (methyl-C3G), suggesting that C3G and/or methyl-C3G act as antioxidants in the tissues.  (+info)

Hyperoxia-induced changes in antioxidant capacity and the effect of dietary antioxidants. (6/731)

We investigated, by measuring oxygen radical absorbance capacity (ORAC), whether hyperoxia causes alterations in antioxidant status and whether these alterations could be modulated by dietary antioxidants. Rats were fed for 8 wk a control diet or a control diet supplemented with vitamin E (500 IU/kg) or with aqueous extracts (ORAC: 1.36 mmol Trolox equivalents/kg) from blueberries or spinach and then were exposed to air or >99% O2 for 48 h. Although the constituents of the extracts were not extensively characterized, HPLC indicated that blueberry extract was particularly rich in anthocyanins, and the spinach extract did not contain any anthocyanins. The ORAC was determined in samples without proteins [serum treated with perchloric acid (PCA); ORACPCA] and with proteins (ORACtot). Hyperoxia induced a decrease in serum protein concentration, an increase in serum ORACPCA, decreases in lung ORACPCA and ORACtot, and an equilibration of proteins and ORACPCA between serum and pleural effusion. These alterations suggested a redistribution of antioxidants between tissues and an increase in capillary permeability during hyperoxia. Only the blueberry extract was effective in alleviating the hyperoxia-induced redistribution of antioxidants between tissues.  (+info)

Protective effects of dietary nasunin on paraquat-induced oxidative stress in rats. (7/731)

The preventive effects of nasunin (delphinidin-3-[4-p-coumaroyl-rhamnosyl(1-->6)glucosid e]-5-glucoside) on paraquat-induced oxidative stress were determined in rats. Decreased food intake and body weight gain and increased lung weight by feeding the rats a diet containing paraquat were clearly suppressed by supplementing nasunin to the paraquat diet. Paraquat feeding increased the concentration of thiobarbituric acid-reactive substances (TBARS) in liver lipids and the atherogenic index, and decreased the liver triacylglycerol level. These effects were also suppressed by supplementing nasunin to the paraquat diet. In addition, catalase activity in the liver mitochondrial fraction was markedly decreased by feeding the paraquat diet, this decrease being partially suppressed by supplementing the paraquat diet with nasunin. These results suggest that nasunin acted preventively against the oxidative stress in vivo that may have been due to active oxygen species formed through the action of paraquat.  (+info)

ANTHOCYANINLESS2, a homeobox gene affecting anthocyanin distribution and root development in Arabidopsis. (8/731)

The ANTHOCYANINLESS2 (ANL2) gene was isolated from Arabidopsis by using the maize Enhancer-Inhibitor transposon tagging system. Sequencing of the ANL2 gene showed that it encodes a homeodomain protein belonging to the HD-GLABRA2 group. As we report here, this homeobox gene is involved in the accumulation of anthocyanin and in root development. Histological observations of the anl2 mutant revealed that the accumulation of anthocyanin was greatly suppressed in subepidermal cells but only slightly reduced in epidermal cells. Furthermore, the primary roots of the anl2 mutant showed an aberrant cellular organization. We discuss a possible role of ANL2 in the accumulation of anthocyanin and cellular organization of the primary root.  (+info)

Berries of highbush blueberry Vaccinium ×covilleanum are very important for human diet by their secondary metabolites that in low amounts are beneficial to human health. The aim of this study was to determine total anthocyanins amounts in berry and berry skin extracts, to investigate their anthibacterial activity and to identify individual anthocyanins. Total anthocyanins in berry extracts ranged from 180 to 270 mg/100 g and from 742 to 1850 mg/100 g in berry skin extracts. The most prevalent anthocyanins were cyanidin-3-arabinoside, delphinidin-3-galactoside, cyanidin-3-galactoside, and petunidin-3-glucoside. The most sensitive to ethanol extracts of berry and berry skin were Citrobacter freundii, Listeria monocytogenes, and Enterococcus faecalis. Pseudomonas aeruginosa and Escherichia coli test cultures were distinguished by the largest resistance. Significant differences between antibacterial activity of berry skin and berry extracts were not determined ...

The available data demonstrate that even in universal metabolic pathways, some species-specific regulatory features of structural genes are present. For instance, in the anthocyanin biosynthesis pathway (ABP), genes may be regulated by ABP-specific regulatory factors, and their expression levels may be strongly associated with anthocyanin pigmentation, or they may be expressed independently of pigmentation. A dataset of orthologous ABP genes (Chs, Chi, F3h, F3h, Dfr, Ans) from monocot and dicot plant species that have distinct gene regulation patterns and different types of pollination was constructed to test whether these factors affect the evolution of the genes. Using a maximum likelihood approach, we demonstrated that although the whole set of the ABP genes is under purifying selection, with greater selection acting on the upstream genes than on the downstream genes, genes from distinct groups of plant species experienced different strengths of selective pressure. The selective pressure on the
Abstract. Anthocyanins have been studied as potential antimicrobial agents against Helicobacter pylori. We investigated whether the biosynthesis and secretion of cytotoxin-associated protein A (CagA) and vacuolating cytotoxin A (VacA) could be suppressed by anthocyanin treatment in vitro. H. pylori reference strain 60190 (CagA+/VacA+) was used in this study to investigate the inhibitory effects of anthocyanins; cyanidin 3-O-glucoside (C3G), peonidin 3-O-glucoside (Peo3G), pelargonidin 3-O-glucoside (Pel3G), and malvidin 3-O-glucoside (M3G) on expression and secretion of H. pylori toxins. Anthocyanins were added to bacterial cultures and Western blotting was used to determine secretion of CagA and VacA. Among them, we found that C3G inhibited secretion of CagA and VacA resulting in intracellular accumulation of CagA and VacA. C3G had no effect on cagA and vacA expression but suppressed secA transcription. As SecA is involved in translocation of bacterial proteins, the down-regulation of secA ...
Anthocyanin pigments furnish a powerful visual output of the stress and metabolic status of Arabidopsis thaliana plants. Essential for pigment accumulation is TRANSPARENT TESTA19 (TT19), a glutathione S-transferase proposed to bind and stabilize anthocyanins, participating in their vacuolar sequestration, a function conserved across the flowering plants. Here, we report the identification of genetic suppressors that result in anthocyanin accumulation in the absence of TT19. We show that mutations in RDR6, SGS3, or DCL4 suppress the anthocyanin defect of tt19 by pushing carbon towards flavonoid biosynthesis. This effect is not unique to tt19 and extends to at least one other anthocyanin pathway gene mutant. This synergy between mutations in components of the RDR6-SGS3-DCL4 siRNA system and the flavonoid pathway reveals genetic/epigenetic mechanisms regulating metabolic fluxes. TRANSPARENT TESTA19 (TT19) encodes a glutathione S-transferase which functions in anthocyanin stabilization and vacuolar
Characterization and quantification of anthocyanins in selected tea cultivars processed into black (aerated) and green (unaerated) tea products was carried out in this study. The anthocyanins were extracted from tea products processed from a number of newly bred purple leaf coloured Kenyan tea cultivars (Camellia sinensis) using acidified methanol/HCl (99:1 v/v). Extracted anthocyanins were purified by C 18 solid phase extraction (SPE) catridges and characterised by HPLC-UV-Visible. They were identified according to their HPLC retention times, elution order and comparison with authentic standards that were available. Total monomeric anthocyanins were determined by the pH-differential method. Although the tea cultivars gave different yields of anthocyanins, the unaerated (green) teas had significantly (p 6 0.05) higher anthocyanin content than the aerated (black) teas. This was attributed to the degradation of anthocyanins by polyphenol oxidase products (catechin O-quinones) formed during the ...
Anthocyanins are naturally occurring polyphenols that impart bright color to fruits, vegetables and plants. In this study, the extraction of anthocyanins from freeze-dried fruit skin of downy rose-myrtle (Rhodomyrtus tomentosa (Ait.) Hassk var. Gangren) was optimized using response surface methodology (RSM). Using 60% ethanol containing 0.1% (v/v) hydrochloric acid as extraction solvent, the optimal conditions for maximum yields of anthocyanin (4.358 ± 0.045 mg/g) were 15.7:1 (v/w) liquid to solid ratio, 64.38 °C with a 116.88 min extraction time. The results showed good fits with the proposed model for the anthocyanin extraction (R2 = 0.9944). Furthermore, the results of high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) analysis of the anthocyanins extracted from the fruit skin of downy rose-myrtle revealed the presence of five anthocyanin components, which were tentatively identified as delphinidin-3-glucoside, cyanidin-3-glucoside, peonidin-3-glucoside,

The TRANSPARENT TESTA GLABRA1 (TTG1) locus controls many apparently unrelated characters of Arabidopsis (catalogued by Koornneef, 1981), several of which appear to be confined to the epidermal cell layer of different tissues. ttg1 mutants have a glabrous phenotype, possessing none of the leaf or stem hairs (trichomes) that normally are derived from the meristematic L1 cell layer. Purple anthocyanin pigments are absent from the ttg1 seed coat, causing the transparent testa phenotype in which the yellow cotyledons are visible through the testa. In wild-type plants, anthocyanins are present in the hypocotyl of seedlings and in the stem and leaves of plants as they age, and they are inducible by many forms of stress, including high light, poor nutrients, or water stress. ttg1 mutants completely lack anthocyanins in the epidermis and in subepidermal layers of leaves and stems. Mucilage normally found in the cell wall of the seed coat is absent in ttg1 mutants. Seeds of ttg1 plants do not require ...
Anthocyanin from the red-color-melinjo peels could be isolated using a polar solvent (ethanol) [ermiziar, 2010]. The amount of hydrocarbons in the structure of anthocyanin might cause that anthocyanin could be isolated using a non polar solvent. The purpose of research is to isolate anthocyanin using non polar solvents (hexane and petroleum ether) with maceration steps for 24 hours and separate solvents using rotary evaporator equipment. The stability of anthocyanin could be observed every week (1,2,3 and 4 weeks) in various environmental conditions (with or without light in refrigerator and open or closed storage). The characterization of anthocyanin was analyzed with visual (physic photo) and or using equipments such as Fourier Transform Infrared Spectroscopy (FTIR) for determining functional groups, Ultraviolet-Visible Spectroscopy (UV/Vis) with 500-550 nm wavelengths for deciding absorption of anthocyanin and atomic absorption spectroscopy (AAS) for analyzing Fe element. The result showed ...
Studies have shown that the consumption of anthocyanins has positive effects on human health. They act as an anti-oxidant, anti-allergic, anti-microbial, anti-inflammatory, and help improve microcirculation of the body. Anthocyanins are known to expedite the process of metabolism of cholesterols and blood sugar. Further, anthocyanins fight oxidative stress, a process known to play a crucial role in escalating heart diseases. Consumption of anthocyanins is also known to reduce the level of obesity in humans.. The rising awareness regarding these factors in the past few years has led to a significant rise in the global consumption of anthocyanins and is expected to be a key driver of the market over the forecast period as well. Additionally, the global anthocyanins market is expected to be driven owing to the steady growth witnessed by the market across developing countries such as India, Brazil, China, Indonesia, and Argentina, in the past few years.. Difficulty in Processing Natural Food Colors ...
In the last decade, there has been an increased interest in anthocyanin-based research with a growing need to accurately measure anthocyanin intake in population studies. Anthocyanin content in foods is known to vary across regions due to climate, soil content and harvesting practices. To accurately measure nutrient intake in population studies, food composition databases tailored to specific regions need to be developed. The aim of this study was to describe the first stage development of an Australian anthocyanin food composition database focusing on fruit and vegetables. A systematic literature search found analytical data on the anthocyanin content of five fruits and two vegetables (purple dragon carrot and red cabbage) out of the total plant-based food category (58 individual fruits and 62 vegetables). In addition, values were found for ten Australian native fruits, of which 9 are not included in the Australian database. Development of an anthocyanin food composition database relies on the

Abstract:Arabidopsis thaliana is the first model plant, the genome of which has been sequenced. In general, intensive studies on this model plant over the past nearly 30 years have led to many new revolutionary understandings in every single aspect of plant biology. Here, we review the current understanding of anthocyanin biosynthesis in this model plant. Although the investigation of anthocyanin structures in this model plant was not performed until 2002, numerous studies over the past three decades have been conducted to understand the biosynthesis of anthocyanins. To date, it appears that all pathway genes of anthocyanins ...
In the present work, a new purification method of anthocyanins with o-dihydroxy arrangement is proposed. This method is based on a ligand-exchange mechanism, using a cationic exchange resin loaded with metallic ions in order to increase the affinity of the resin to the anthocyanin(s) with o-dihydroxy arrangement. This method was used to purify the main anthocyanin (cyanidin-3-glucoside; Cy-3-glc) from the anthocyanic methanolic extract of blue corn. The best sorption result was using Fe(III) in its ion form. The purification procedure begins with the formation of a metal-anthocyanin complex (Cy-3-glc-Fe) which was optimal at pH 5, followed by a NaOH 0.1?M elution process in order to eliminate anthocyanins without o-dihydroxy arrangement, sugars, and organic acids. Finally, the pure anthocyanin is obtained by adding HCl 0.1?M which breaks the metal-anthocyanin complex. ...
Pelargonidin is one of the six anthocyanin compounds, and is both the simplest in structure and is red. It is commonly associated with strawberries, although it is present in all berries. Seems to have its bioactivity saved by Quercetin.
While anthocyanins are proven to be effective in inhibiting tumour cell proliferation, the underlying mechanisms remain unclear. This research aims to explore the glycosylation of anthocyanins in the tumour inhibitory effects and the potential mechanism. The tumour inhibitory effect on mouse colon cancer cells (MC38) was examined by MTT and flow cytometric analyses. The inhibitory pathway of anthocyanin was explored by assessment of tumour cell mitochondrial membrane potential (MMP), the caspase-3 and caspase-9 activity, as well as the cell energy metabolism in terms of the glucose uptake, the NAD+/NADH ratio and the ATP level. We found that 500 μM bilberry anthocyanins extract (BAE) induced 48.1% mitochondrial damage, activated the downstream caspase cascade to form apoptotic bodies (caspase-3 activity increased by 169%, caspase-9 activity increased by 186%), and inhibited cell proliferation (survival rate: 55.97%, 24 h). In contrast, the same concentration of anthocyanidin (cyanidin) led to marginal

Our objective was to develop a robust system for anthocyanin-based color intensification, with high-encapsulation capacity and improved stability of the encapsulated natural colorant. Catechin was used to modulate the copigmentation and encapsulation of anthocyanins in counter-ionic polyelectrolyte complexes (PECs) composed of chondroitin sulfate and chitosan. Results showed that catechin copigmentation significantly intensified red color of formulations both with and without encapsulation in PECs and improved the anthocyanin encapsulation efficiency by forming additional dense network through hydrogen bonding. A series of stability assays revealed that anthocyanin stabilizing effect of system depended on the formulated pH and adding order of catechin. The strongest retaining capacity of anthocyanin was observed when catechin was copigmented with anthocyanin directly in PECs at pH 3.3, while the coated layer of catechin covered on PECs would be more effective at pH 4.0 and 5.0. Furthermore, we
Seven red raspberry (Rubus Ideaus L.) samples from Oregon, Washington, British Columbia and New Zealand were processed into juice. These, along with three juice samples supplied from West Germany were analyzed by high performance liquid chromatography, (HPLC), for nonvolatile acid, sugar, anthocyanin and anthocyanidin composition. In order to quantitate the compounds of interest, particular attention was given to selection and improvement of HPLC analytical procedures. Adequate resolution of malic acid from isocitric by reverse phase C-18 chromatographic media was achieved using a two column system. The more uniform response of analytes to refractive index detection allowed for quantitation of isocitric acid. Sugar analysis based on a crosslinked cation exchange resin required removal of the acids from the juice via anion exchange. Resolution of anthocyanin pigments was achieved using as organic modifier 15% acetic acid. Acetic acid (15%) demonstrated high selectivity in resolving pigments with ...
Abaxially anthocyanic leaves of deeply-shaded understorey plants play important ecological significance for the environmental adaption. In contrast to the transient pigmentation in other plants, anthocyanins are permanently presented in these abaxially red leaves, however, the mechanism for the pigment maintenance remains unclear. In the present study, we investigated phenolic metabolites that may affect pigment stability and degradation in Excoecaria cochinchinensis (a bush of permanently abaxial-red leaves), via a comparison with Osmanthus fragrans (a bush of transiently red leaves). High levels of galloylated anthocyanins were identified in the Excoecaria but not in the Osmanthus plants. The galloylated anthocyanin showed slightly higher stability than two non-galloylated anthocyanins, while all the 3 pigments were rapidly degraded by peroxidase (POD) in vitro. High levels of hydrolysable tannins [mainly galloylglucoses/ellagitannins (GGs/ETs)] were identified in Excoecaria but none in Osmanthus. GGs
7 Life Changing Reasons To Eat More Anthocyanins + Top Foods:. By now, were all aware of the incredible health benefits of eating fruits and vegetables. However, many people dont realize exactly why these fresh foods are so amazing.. While they boast an array of health benefits - including vitamins, minerals and fiber - fruits and vegetables also contain some special compounds that can help protect us from an ever-growing list of diseases.. One group of such of compounds is the anthocyanins - a type of flavonoid. You may already be familiar with flavonoids - a family of powerful antioxidants - from reading up on the healthful properties of green tea, cocoa and red wine.. But anthocyanins deserve special recognition for their protective properties. So powerful are the anthocyanins that tests have shown they can yield twice the antioxidant power of vitamin C!. Another great benefit of anthocyanins is that they are so easily recognized! Just looking at your plate is enough to tell if your food ...
MtPAR is a proanthocyanidin (PA) biosynthesis regulator; the mechanism underlying its promotion of PA biosynthesis is not fully understood. Here, we showed that MtPAR promotes PA production by a direct repression of biosynthesis of isoflavones, the major flavonoids in legume, and by redirecting immediate precursors, such as anthocyanidins, flux into PA pathway. Ectopic expression of MtPAR repressed isoflavonoid production by directly binding and suppressing isoflavone biosynthetic genes such as isoflavone synthase (IFS). Meanwhile, MtPAR up-regulated PA-specific genes and decreased the anthocyanin levels without altering the expression of anthocyanin biosynthetic genes. MtPAR may shift the anthocyanidin precursor flux from anthocyanin pathway to PA biosynthesis. MtPAR complemented PA-deficient phenotype of Arabidopsis tt2 mutant seeds, demonstrating their similar action on PA production. We showed the direct interactions between MtPAR, MtTT8 and MtWD40-1 proteins from Medicago truncatula and ...
Anthocyanins are synthesized directly from anthocyanidins by glycosylation (adding of a sugar to a protein) at the 3 and 5 positions of the C ring and are accumulated in the berry skins from veraison until full maturity. After synthesis in the cytosol (fluid portion of the cell cytoplasm), anthocyanins are transported into the vacuole (cell organelle responsible for a number of functions including nutrient storage) where they are stored as colored coalescences called anthocyanic vascular inclusions (Flamini, et al ...

The level of pigment in the F2s was a surprise as I hadnt noted any anthocyanin expression in the parent varieties. After seeing the F2s, I re-examined some Tiny Tim plants grown this year and found they did have anthocyanin expression. The fruit show a level of anthocyanin production comparable to the high-fruit-pigment F2s (image #5), but the small size of the fruit made it hard to notice. The F1 showed a pigment level like the medium-fruit-pigment F2s, suggesting it is a single trait with partial dominance. The color of the calyx and leaf/stem was comparable to the F2 plants with the middle level of pigment for each feature. Looking into the lineage of Tiny Tim suggests the middle-pigment trait was contributed from S. pimpinellifolium, used in the breeding to contribute small fruit size to Tiny Tim. As anthocyanin pigments on the shoulder is common in many wild tomato relatives, I suspect the fruit trait also came from S. pimpinellifolium. ...

The cross talk among hydrogen peroxide (H2O2) nitric oxide (NO) and UV RESISTANCE LOCUS8 (UVR8) in UV-B-induced anthocyanin accumulation in the hypocotyls of radish sprouts was investigated. H2O2-induced anthocyanin accumulation and expression were significantly suppressed by co-treatment with 2-phenyl-4 4 5 5 (PTIO a NO scavenger) which was parallel with the expression of anthocyanin biosynthesis-related transcription factors and structural genes. All these results demonstrate that both H2O2 and NO are involved in UV-B-induced anthocyanin accumulation and there is a crosstalk between them as well as a classical UVR8 pathway. Anthocyanins are plant secondary metabolites synthesized through the flavonoid pathway generating the characteristic reddish bluish and purple hues which contribute to flower pigmentation attraction of pollinators and seed dispersers1. In addition they are also important as antioxidant molecules to protect plant cells against damage by reactive oxygen species (ROS)2 ...
The adsorption of ochratoxin A (OTA) by yeasts is a promising approach for the decontamination of musts and wines, but some potential competitive or interactive phenomena between mycotoxin, yeast cells, and anthocyanins might modify the intensity of the phenomenon. The aim of this study was to examine OTA adsorption by two strains of Saccharomyces cerevisiae (the wild strain W13, and the commercial isolate BM45), previously inactivated by heat, and a yeast cell wall preparation. Experiments were conducted using Nero di Troia red wine contaminated with 2 μg/L OTA and supplemented with yeast biomass (20 g/L). The samples were analyzed periodically to assess mycotoxin concentration, chromatic characteristics, and total anthocyanins over 84 days of aging. Yeast cell walls revealed the highest OTA-adsorption in comparison to thermally-inactivated cells (50% vs. 43% toxin reduction), whilst no significant differences were found for the amount of adsorbed anthocyanins in OTA-contaminated and control wines.

The lability of anthocyanins and flavonols extracted from grape (Vitis vinifera L.) skin with commonly used extraction solvents was examined. Results indicate that both anthocyanins and flavonol glycosides are unstable in even mildly acidic extraction solvents and highly labile in 1% hydrochloric acid in methanol, the most commonly used extraction solvent. While lability of anthocyanins has previously been reported, this is the first report of flavonol glycoside stability in these solvents. As a result of these observations, an extraction protocol was developed that maximized anthocyanin (malvidin-3-O-glucoside, malvidin-3-O-acetylglucoside, and malvidin-3-O-p-coumaroylglucoside) and flavonol (quercetin-3-O-glucoside and quercetin-3-O-glucuronide) extraction while minimizing degradation in the time between extraction and HPLC analysis. A range of acidified methanol solvents including hydrochloric, formic, acetic, citric, and maleic acids were tested together with acidulated ethanol and several ...
Drug Class and Mechanism. Acai is a rich source of anthocyanins and other phenolics. Anthocyanins are compounds that have potent antioxidant activity, allowing for the neutralization of potentially harmful free radicals. By neutralizing these free radicals, anthocyanins from Acai may serve to maintain the healthy function of numerous systems and organs. Some of the anthocyanins that have been found in Acai include cyanidin-3-glucoside and cyanidin-3-glucoside-coumarate. Other phenolics include catechin and epi-catechin (the same compounds in green tea), quercetin derivatives and other flavonoids. It is likely that the synergistic effects of these compounds as present in acai fruit are responsible for its potent antioxidant activities ...
Several polyphenolic compounds and their conjugated metabolites were detected and quantified in plasma samples of older adults consuming freeze-dried strawberry powder for 90 days. Parent anthocyanins, including the primary glucuronide conjugate of pelargonidin, three urolithin derivatives and fifteen phenolic acid metabolites were quantified. Important findings included: evidence for persistence of anthocyanins and some phenolic acid metabolites in circulation with chronic strawberry intake, enhancement in 2 h anthocyanin/metabolite and phenolic acids (4-hydroxybenzaldehyde, trans-cinnamic acid, hippuric acid and p-coumaric acid) concentrations after a strawberry drink supplementation, and urolithin metabolites were observed only in 68% of subjects with large inter individual variability. In acute pharmacokinetic studies conducted by our group22,23 and others,15 strawberry anthocyanins peaked within 1-3 hours and were back to baseline concentrations by 8-10 hours after consumption.22 However, ...
PRODUCTION OF ANTHOCYANIN PIGMENT 1 encodes a putative MYB domain containing transcription factor involved in anthocyanin metabolism and radical scavenging. PAP1 promotes the synthesis of phenylpropanoid-derived compounds such as anthocyanins and proanthocyanidin, probably together with GL3 and BHLH2. Additionally, PAP1 was demonstrated to interact with JAZ proteins to regulate anthocyanin accumulation and is essential for the sucrose-mediated expression of the dihydroflavonol reductase gene ...
Background & Aims: Anthocyanins may have beneficial effects on lipid metabolism and inflammation and are demonstrated to have hepatoprotective properties in models of restraint-stressand chemically-induced liver damage. However, their potential to protect against non-alcoholic steatohepatitis (NASH) under conditions relevant for human pathogenesis remains unclear. Therefore, we studied the effects of the standardised anthocyanin-rich extract Mirtoselect on diet-induced NASH in a translational model of disease.. Methods: ApoE*3Leiden mice were fed a Western-type cholesterol-containing diet without (HC) or with 0.1% (w/w) Mirtoselect (HCM) for 20 weeks to study the effects on diet-induced NASH.. Results: Mirtoselect attenuated HC-induced hepatic steatosis, as observed by decreased macro-and microvesicular hepatocellular lipid accumulation and reduced hepatic cholesteryl ester content. This anti-steatotic effect was accompanied by local anti-inflammatory effects in liver, as demonstrated by reduced ...

Rapidly accumulating laboratory and clinical research evidence indicates that anthocyanins exhibit anticancer activity and the evaluation of bilberry anthocyanins as chemo‑preventive agents is progressing. It has previously been demonstrated that anthocyanins upregulate tumor suppressor genes, induce apoptosis in cancer cells, repair and protect genomic DNA integrity, which is important in reducing age‑associated oxidative stress, and improve neuronal and cognitive brain function. Bilberry anthocyanins have pronounced health effects, even though they have a low bioavailability. To increase the bioavailability, Bilberry was encapsulated in 5.5 nm diameter liposomal micelles, called NutraNanoSpheres (NNS), at a concentration of 2.5 mg/50 µl [25% (w/w) anthocyanins]. These Bilberry NNS were used to study the apoptotic/cytotoxic effects on K562 Human Erythroleukemic cancer cells. Flow cytometric fluorescent quantification of the uptake of propidium iodide in a special cell viability formulation ...
I have been wanting to try purple sweet potatoes since reading about the Okinawa people. In this little Japanese island, there wasnt a big variety of food and locals mostly ate purple sweet potatoes, complemented with rice and legumes and very little more. They have estimated that animal proteins altogether contributed slightly above 1% of the total calorie intake of this population, making them 99% vegetarian.. What made the Okinawan famous, though, was their longevity and the virtual absence of disease up to a very old age. Ever heard of the Blue Zones? It is a list of places in the world where the highest proportions of very old folks can be found. Okinawa is one of them.. It has been said that the very high daily intake of purple sweet potato was one of the reasons for the incredible good health of Okinawans. This interesting tuber, which is used as a coloring agent in some places (South America), owes its color to the massive presence of powerful antioxidants called anthocyanins. ...

The presence of acylation with substituted cinnamic acids permits us to obtain solutions not only with a red color (the ...
ABSTRACT Title of Dissertation: PURPLE PEPPER PLANTS, AN ANTHOCYANIN POWERHOUSE: EXTRACTION, SEPARATION AND CHARACTERIZATION Cassandra Lynn Taylor Doctor of Philosophy, 2014 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry and Biochemistry Most plants have multiple anthocyanins present that produce their color. In contrast, the foliage of the purple pepper plant (Capsicum annuum L.) contains high concentrations of a single anthocyanin delphinidin-3-p-coumaroylrutinoside-5-glucoside (Dp-3-p-coumrut-5-glc) in the foliage, making it very unique. This provides an excellent platform to extract the single anthocyanin at high concentrations. A food-grade extraction method was developed using 1% hydrochloric acid and 200 proof ethanol (1% HCl/EtOH) in order to remove the intact anthocyanin. A separation method using High Performance Liquid Chromatography (HPLC) was developed to identify Dp-3-p-coumrut-5-glc. The retention time was compared with the Blue Ribbon Iris, a known ...
Antioxidant activity, total anthocyanins, phenols and flavonoids Contents were monitored in a callus induced from stem segment culture of sweetpotato (Ipomoea batatas L.) Abees, the Egyptian orange-fleshed cultivar in addition to four genotypes (199062.1-1999026.1-199015.14- 199004.2) obtained from the International Potato Centre (CIP). In vitro callus culture were grown over period of four weeks in dark on Murashige and Skoog (MS) medium supplemented with different concentrations of osmotic potential induced by (0.03, 0.1, 0.15 molar) sucrose or sorbitol, MS medium without any sugar used as a control. It was found that the dominant DPPH radical-scavengers of Abees cultivar was due to the presence of anthocyanins and phenolic compounds rather than flavonoides, while at 199062.1 was as a consequence of flavonoids and at 199004.2 was a result of the phenolic compounds. Anthocyanins and flavonoids accumulation stimulated by increasing the sugar concentration up to 0.1 M and 0.15 M respectively ...
Accumulation of abaxial anthocyanins is an intriguing leaf trait particularly common among deeply shaded understorey plants of tropical and temperate forests whose ecological significance is still not properly understood. To shed light on it, possible ecophysiological roles of abaxial anthocyanins were tested in the perennial understorey herb of temperate deciduous forests Saxifraga hirsuta, chosen as a model species due to the coexistence of green and anthocyanic leaves and the presence of an easily removable lower anthocyanic epidermis. Anthocyanins accumulated during autumn, which temporally matched the overstorey leaf fall. Patterns of development of abaxial anthocyanins and direct measurements of photochemical efficiency under monochromatic light were not consistent with a photoprotective hypothesis. Enhancement of light capture also seemed unlikely since the back-scattering of red light towards the lower mesophyll was negligible. Seed germination was similar under acyanic and anthocyanic ...
BACKGROUND: Anthocyanins, which are colored pigments, have long been used as food and pharmaceutical ingredients due to their potential health benefits, but the intermediate signals through which environmental or developmental cues regulate anthocyanin biosynthesis remains poorly understood. Fleshy fruits have become a good system for studying the regulation of anthocyanin biosynthesis, and exploring the mechanism underlying pigment metabolism is valuable for controlling fruit ripening. RESULTS: The present study revealed that ABA accumulated during Lycium fruit ripening, and this accumulation was positively correlated with the anthocyanin contents and the LbNCED1 transcript levels. The application of exogenous ABA and of the ABA biosynthesis inhibitor fluridon increased and decreased the content of anthocyanins in Lycium fruit, respectively. This is the first report to show that ABA promotes the accumulation of anthocyanins in Lycium fruits. The variations in the anthocyanin content were ...
SCOPE Blackcurrants (Ribes nigrum L., Grossulariaceae) contain high amounts of anthocyanin polyphenols, which have antioxidant and anti-carcinogenic health benefits. This study analyzed the potential phytoestrogenic effects of blackcurrant extract (BCE) in breast cancer (MCF-7) and human endometrial cancer (Ishikawa) cell lines that over-express estrogen receptor alpha (ERα), as well as in immature female rats. METHODS AND RESULTS Microarray analysis and Ingenuity® Pathway Analysis showed that BCE activated the ERα pathway, whereas quantitative-PCR confirmed that BCE and four types of anthocyanins up-regulated genes downstream of ERα. BCE (0.1-1.0 μg/mL) and anthocyanins (0.1-10 μM) induced MCF-7 cell proliferation; however, this effect was blocked by ER antagonist fulvestrant. Flow cytometry showed that anthocyanins reduced and increased the number of MCF-7 cells in the G0/G1 and G2/M phases, respectively. Anthocyanins stimulated ERα transcriptional activity in human ERα reporter assays and
Dear Friends. As we learned in last fridays Forward Thinking, epidemiological studies have suggested that reduction in cardiovascular disease, cancer risk and a range of other chronic disease conditions is linked to consumption of anthocyanins, betalains, chlorophylls and carotenoids (Mary Ann Lila 2004)-the primary pigments of colorful fruits and vegetables. Quite simply we need to eat 5-13 servings of vegetables and fruits a day (Harvard School of Public Health, see Green Facts below).. Last week we looked at betalains derived from red beetroot and cactus pears and their multitude of benefits. This week well look at anthocyanins and the protection they provide for a diverse array of diseases.. Heart Disease. Pure anthocyanins are up to seven times more effective as antioxidants inhibiting lipid peroxidation than alpha tocopherol. Anthocyanins in red wines and grape juice contributed to the ability of these dietary sources to inhibit heart attacks, by virtue of their antithrombotic potential, ...

Wisconsin Cranberry Newsletter Integrated Pest Managements for Cranberries j Volume VH, Number 9, September 5, 1993 Anthocyanin Development Since fruit color is so important to the cranberry industry, 1 thought I would take a little space and describe a little about fruit color development in cranberry. The red color of mature cranberries is caused by the development of ,thocyanin pigments in the few outermost cell layers. This is also associated with a dilution of chlorophyll as the berries enlarge. Anthocyanins are fairly complex molecules which require signiscant amounts of energy to create. Anthocyanin production is broadly regulated at two levels: environment and genetics. Development of fruit color is usually associated with bright sunny days and cool nights. Research has clearly shown that the greatest Amount of color develops with the coolest weather and that in the immediate preharvest period warm temperatures lead to poor fruit color. To: most intense color is also formed where ...
Leaves of Arrabidaea chica (Humb. Bonpl.) Verlot are rich in anthocyanins and have been used as a medicinal plant in the Amazon region. In order to obtain different extracts from this plant, a sequential extraction in fixed bed was carried out at 40 °C and 300 bar, using supercritical carbon dioxide (scCO2) in a first step, and a mixture containing CO 2/ethanol/water at mass ratios of approximately 80/20/0, 80/14/6 and 80/10/10 in a second extraction step. The residue from the second step was extracted with water at 40 C and atmospheric pressure. Ethanolic, aqueous and hydroalcoholic (70:30, v:v) extracts were also obtained by conventional extraction methods at atmospheric pressure. All extracts were analyzed for global extraction yield, total phenolic content, total flavonoids, and carajurin content. High performance liquid chromatography (HPLC) was used both to quantify carajurin, which is the main anthocyanin component of A. chica, and to monitor qualitatively two other anthocyanin pigments ...

As well as activating the promoters of the two PA-specific genes, VvANR and VvLAR, VvMYBPA1 also activated the promoters of general flavonoid pathway genes, whereas the Arabidopsis TT2 regulator appeared to be more specific for ANR in this transient assay (Fig. 4). Anthocyanin and PA biosynthesis share the general flavonoid pathway enzymes until LDOX catalyzes the synthesis of anthocyanidins (Abrahams et al., 2003), which are substrates for both anthocyanin synthesis via UFGT and PA synthesis catalyzed by ANR and LAR (Fig. 1). Therefore, UFGT and ANR/LAR are branch enzymes leading to anthocyanin or PA accumulation, respectively, and represent possible control points between the two flavonoid branches. Our results obtained with the transient promoter assay revealed the ability of VvMYBPA1 to activate the PA-specific branch genes VvANR and VvLAR1, showing its capacity to control PA synthesis in grapevine. Furthermore, VvMYBPA1 was not able to induce the VvUFGT promoter, suggesting it specifically ...
PURPLE CORN. Purple corn contains a variety of phytonutrients (plant nutrients) including massive amounts of phenolics and anthocyanin. Research shows that crops with the highest phenolic and anthocyanin content also have the highest antioxidant activity. Anthocyanin are a type of complex flavonoid that produces blue, purple or red colors. Anthocyanin are anti-inflammatory and encourage connective tissue regeneration. As well as being powerful antioxidants that keep us looking young and protected from disease, they promote blood flow and reduce cholesterol. It appears that anthocyaninmay stabilize and protect capillaries and blood vessels from free radical damage, and they have been shown to promote collagen formation (which is great for our skin) and improve circulation..

Furthermore, LC-QTOF-MS/MS based metabolomics and HPLC analyses were performed for the identification and quantification of individual ...
You might be able to find purple sweet potatoes locally. They have a bold purple flesh, but the color of the skin may differ depending on which variety you find in your area. In the U.S., youre more likely to find Stokes Purple sweet potatoes, which have a dark maroon skin. The rich color of the skin and flesh is due to the concentration of anthocyanins, a powerful antioxidant. These antioxidants are actually more effective at trapping free radicals (and preventing oxidative stress) than the anthocyanins in red cabbage and grapes.[6] Look for these deep-hued potatoes at your local farmers market or organic grocery store in late summer through April. Try to use them within 2 weeks as they wont last as long as white and yellow potatoes.[7] When cooked, purple sweet potatoes maintain their gorgeous color and they look absolutely incredible in this Buddha Bowl recipe ...

The influence of a simulated digestive process on some biochemical and biological aspects of strawberry grape (Vitis labrusca) was investigated. The amount of total polyphenols and anthocyanins as well as the antioxidant power were evaluated. Results evidenced that the simulated gastrointestinal transit caused a decrease of the polyphenols content and total anthocyanins; these last, however, were more resistant than polyphenols, decreasing only of 50% respect to the initial value (31.50 μg/ml of extract). The extract exhibited an excellent antioxidant power (EC50 3.8 mg/ml), which decreased of about four times after the simulated gastrointestinal transit. The antimicrobial activity of the extract, evaluated against three Escherichia coli, Pseudomonas aeruginosa and Bacillus cereus pathogen strains was enhanced by the simulated digestion, with an increase of the inhibition halo.
Blueberries or bilberries contain large amounts of anthocyanins, making them one of the richest sources of dietary anthocyanin. These berries are widely consumed as fresh and dried fruits, jams, or juices. Considerable attention has been focused on t

Aronia melanocarpa, native to eastern North America, has become popular in Eastern Europe and Russia. Aronia melanocarpa fruits are one of the richest plant sources of phenolic substances, mainly anthocyanins--glycosides of cyanidin. Anthocyanins are water soluble pigments accounting for the dark blue and even black color of the fruits. Administered orally they can be absorbed as intact glycosides. Aronia melanocarpa fruit juice and anthocyanins derived from the fruits have been studied intensively for the last 15 years. Most of the effects of Aronia melanocarpa anthocyanins are due to their high antioxidative activity. Our investigations have demonstrated a remarkable hepatoprotective, a very good gastroprotective and a pronounced anti-inflammatory effect of Aronia melanocarpa fruit juice in rats as well as a bacteriostatic activity in vitro against Staphylococcus aureus and Escherichia coli and an antiviral activity against type A influenza virus. Research of other authors has demonstrated ...

Phenolic compounds are known to have biological activity with beneficial effects on human health. Fruit of cultivated tomatoes (Solanum lycopersicum L.) are a major source of phenolics in the U.S. diet because this crop is the second most consumed vegetable per capita, but actual levels are low compared to other fruits and vegetables. Anthocyanins are an important class of phenolic phytonutrients known for their antioxidant properties and color. Tomato fruits do not normally posses anthocyanins, but we have developed lines which express substantial quantities in the fruit. We wished to quantify levels of total phenolics and anthocyanins in anthocyanin expressing tomato fruit in different production systems and compare to that of normal tomatoes. Epidermis and pericarp tissue of three advanced breeding lines of anthocyanin-fruit tomatoes and three lines of nonanthocyanin-fruit tomatoes, both grown in organically and conventionally managed systems, were assayed for total phenolics and total ...
The transcriptional regulators for anthocyanin pigmentation include proteins containing R2R3-MYB domains, bHLH domains and conserved WD40 repeats, and their interactions determine the set of genes to be expressed. Spontaneous ivory seed (ivs) mutants of Ipomoea purpurea displaying pale pigmented flowers and ivory seeds are caused by insertions of DNA transposons into the bHLH2 gene that encodes a bHLH transcriptional regulator. A partial reduction in the expression of all structural genes encoding enzymes for anthocyanin biosynthesis was observed in the young flower buds of these ivs mutants. The DFR-B and ANS transcripts were completely abolished in the ivs seed coats, whereas the early biosynthetic genes for flavonol biosynthesis remained active. The production and accumulation of both proanthocyanidin and phytomelanin pigments in the ivory seed coats were drastically reduced. Moreover, the unbranched trichomes in the ivory seeds were smaller in size and fewer in number than those in the ...
I guess I put my foot in it then :) OK....roll on luminescent rather than normal fluorescent crop plants ;) I do wonder whether if rape was not so garish whether there would be less antagonism towards it.. I often hear...those ugly yellow fields..I just wonder (fancifully) if changing the colour of the petals by (say...) ectopic anthocyanin production in them to produce red/purple/brown petals would lessen the criticisms.

The ammonia test is a well-known method used for detecting the presence of anthocyanin in plant tissues. If anthocyanin is present a green or bluish colour usually develops upon fuming, though possibly other substances in the cell sap may modify this green or bluish appearance. In addition to the many fumings made with ammonia in the course of these experiments, petals have been bleached with SO2, and the reactions of different flower colours with these two reagents noted.. The observations may be briefly summarised as follows:. SO2.- SO2 does not affect the flavones. It half bleaches the deeper coloured petals and almost entirely bleaches tinged varieties. Penetration is increased if the petal is first fumed in ammonia and then bleached-complete removal of the anthocyanin pigments resulting, thus revealing the flavone ground.. Ammonia.- (a) Magenta and purple flowers give green and bluish-green reactions. (b) Orange and scarlet give an intense reddish-brown coloration. (c) Intermediate forms ...

Link to Pubmed [PMID] - 28677124. Mol. Microbiol. 2017 Sep;105(6):880-900. Aspergillus fumigatus, a ubiquitous human fungal pathogen, produces asexual spores (conidia), which are the main mode of propagation, survival and infection of this human pathogen. In this study, we present the molecular characterization of a novel regulator of conidiogenesis and conidial survival called MybA because the predicted protein contains a Myb DNA binding motif. Cellular localization of the MybA::Gfp fusion and immunoprecipitation of the MybA::Gfp or MybA::3xHa protein showed that MybA is localized to the nucleus. RNA sequencing data and a uidA reporter assay indicated that the MybA protein functions upstream of wetA, vosA and velB, the key regulators involved in conidial maturation. The deletion of mybA resulted in a very significant reduction in the number and viability of conidia. As a consequence, the ΔmybA strain has a reduced virulence in an experimental murine model of aspergillosis. RNA-sequencing and ...
