“…The ACN composition can vary between different sources and varieties of foods [5], depending on whether they are fresh, frozen or dried [6], with seasonability and environmental stress [7], as well as with food storage and preparation techniques (i.e., peeled, unpeeled) indicating that their presence might be concentrated in specific areas of fruits and vegetables such as the skin or flesh [5,8]. In 2002, the consumption of ACNs was estimated to be 12.5 mg/day/person in the United States, although it is anticipated that this number has risen due to the increased popularity of the so-called 'superfood' market for health and wellbeing [9][10][11].…”

Anthocyanins and Human Health—A Focus on Oxidative Stress, Inflammation and Disease

Consumption of anthocyanins (ACNs), due to their antioxidant, anti-inflammatory and anti-apoptotic effects, has been proposed for the prevention and treatment of several different diseases and conditions. ACNs are recognized as one of the leading nutraceuticals for prolonging health benefits through the attenuation of oxidative stress, and inflammatory or age-related diseases. Increased consumption of ACNs has the potential to attenuate the damage ensuing from oxidative stress, inflammation, enhance cardiometabolic health, and delay symptoms in predisposed neuropathology. A myriad of evidence supports ACN consumption as complementary or standalone treatment strategies for non-communicable diseases (NCDs) including obesity, diabetes, cardiovascular disease (CVD), neurodegenerative diseases, as well as, more recently, for the modulation of gut bacteria and bone metabolism. While these findings indicate the beneficial effects of ACN consumption, their food sources differ vastly in ACN composition and thus potentially in their physiological effects. Consumption of foods high in ACNs can be recommended for their potential beneficial health effects due to their relatively easy and accessible addition to the everyday diet.

“…Numerous studies have demonstrated that a wide range of environmental stresses can stimulate the production and accumulation of anthocyanins in plants [ 70 , 71 , 72 ], suggesting that these secondary metabolites may be closely correlated with the tolerance of plants to adverse environmental conditions as indicated by earlier studies [ 31 , 33 ]. Although light is required for plants to generate energy for growth and development, there are potential risks in capturing light energy by the photosynthetic apparatus of plants [ 73 , 74 ].…”

Rapeseed (Brassica napus) is one of the major important oil crops worldwide and is largely cultivated in the Qinghai-Tibetan plateau (QTP), where long and strong solar-radiation is well-known. However, the molecular mechanisms underlying rapeseed’s response to light stress are largely unknown. In the present study, the color of rapeseed seedlings changed from green to purple under high light (HL) stress conditions. Therefore, changes in anthocyanin metabolism and the transcriptome of rapeseed seedlings cultured under normal light (NL) and HL conditions were analyzed to dissect how rapeseed responds to HL at the molecular level. Results indicated that the contents of anthocyanins, especially glucosides of cyanidin, delphinidin, and petunidin, which were determined by liquid chromatography-mass spectrometry (LC-MS), increased by 9.6-, 4.2-, and 59.7-fold in rapeseed seedlings exposed to HL conditions, respectively. Next, RNA-sequencing analysis identified 7390 differentially expressed genes (DEGs), which included 4393 up-regulated and 2997 down-regulated genes. Among the up-regulated genes, many genes related to the anthocyanin-biosynthetic pathway were enriched. For example, genes encoding dihydroflavonol reductase (BnDFR) and anthocyanin synthase (BnANS) were especially induced by HL conditions, which was also confirmed by RT-qPCR analysis. In addition, two PRODUCTION OF ANTHOCYANIN PIGMENTATION 2 (BnPAP2) and GLABRA3 (BnGL3) genes encoding MYB-type and bHLH-type transcription factors, respectively, whose expression was also up-regulated by HL stress, were found to be associated with the changes in anthocyanin biosynthesis. Many genes involved in the jasmonic acid (JA)-biosynthetic pathway were also up-regulated under HL conditions. This finding, which is in agreement with the well-known positive regulatory role of JA in anthocyanin biosynthesis, suggests that the JA may also play a key role in the responses of rapeseed seedlings to HL. Collectively, these data indicate that anthocyanin biosynthesis-related and JA biosynthesis-related pathways mediate HL responses in rapeseed. These findings collectively provide mechanistic insights into the mechanisms involved in the response of rapeseed to HL stress, and the identified key genes may potentially be used to improve HL tolerance of rapeseed cultivars through genetic engineering or breeding strategies.

“…Anthocyanins are a group of flavonoid-type secondary metabolites found throughout the plant kingdom. They play a crucial role in plant reproduction by attracting pollinators and seed dispersers through pigmentation in flowers, fruits and vegetative tissues [ 42 ], and they also serve as protectants against a variety of abiotic and biotic stresses [ 23 , 43 , 44 , 45 , 46 , 47 ]. Anthocyanins accumulate in response to abiotic stresses such as drought, cold, and high light intensity.…”

Zoysia japonica is a warm-season turfgrass that is extensively used in landscaping, sports fields, and golf courses worldwide. Uncovering the low-temperature response mechanism of Z. japonica can help to accelerate the development of new cold-tolerant cultivars, which could be used to prolong the ornamental and usage duration of turf. A novel Z. japonica biotype, YueNong-9 (YN-9), was collected from northeastern China for this study. Phenotypic measurements, cold-tolerance investigation, and whole-transcriptome surveys were performed on YN-9 and LanYin-3 (LY-3), the most popular Z. japonica cultivar in Southern China. The results indicated the following: YN-9 has longer second and third leaves than LY-3; when exposed to the natural low temperature during winter in Guangzhou, YN-9 accumulated 4.74 times more anthocyanin than LY-3; after cold acclimation and freezing treatment, 83.25 ± 9.55% of YN-9 survived while all LY-3 leaves died, and the dark green color index (DGCI) value of YN-9 was 1.78 times that of LY-3; in YN-9, there was a unique up-regulation of Phenylalanine ammonia-lyase (PAL), Homeobox-leucine Zipper IV (HD-ZIP), and ATP-Binding Cassette transporter B8 (ABCB8) expressions, as well as a unique down-regulation of zinc-regulated transporters and iron-regulated transporter-like proteins (ZIPs) expression, which may promote anthocyanin biosynthesis, transport, and accumulation. In conclusion, YN-9 exhibited enhanced cold tolerance and is thus an excellent candidate for breeding cold-tolerant Z. japonica variety, and its unique low-temperature-induced anthocyanin accumulation and gene responses provide ideas and candidate genes for the study of low-temperature tolerance mechanisms and genetic engineering breeding.
