“…Cold stress stimulates anthocyanin biosynthesis by up-regulating the expression of TF genes, and anthocyanin biosynthetic genes have been well documented in recent years [1,21,[23][24][25]31,48]. For example, MdMYBA specifically combines to the ANS promoter and activates anthocyanin production under low temperature conditions in apple skin [49], whereas MdbHLH3 binds to the promoters of MdDFR and MdUFGT, accompanied with a regulatory MdMYB1 gene to activate their expressions [50].…”

“…Anthocyanin is a water-soluble pigment of the flavonoid family in plant secondary metabolism, and is responsible for gorgeous coloration and stress resistance in fruits and vegetables [1]. A high concentration of anthocyanin is nontoxic and possesses as a characteristic of reduction the teratogenic and mutagenic incidence; therefore, anthocyanin is widely used in the food industry [2].…”

To elucidate the effect of low temperature on anthocyanin biosynthesis in purple head Chinese cabbage, we analyzed anthocyanin accumulation and related gene expression in the seedlings of purple head Chinese cabbage, white head parent Chinese cabbage, and its purple male parent under a normal 25 °C temperature and a low 12 °C temperature. Anthocyanin accumulation in purple lines was strongly induced by low temperature, and the total anthocyanin content of seedlings was significantly enhanced. In addition, nearly all phenylpropanoid metabolic pathway genes (PMPGs) were down-regulated, some early biosynthesis genes (EBGs) were up-regulated, and nearly all late biosynthesis genes (LBGs) directly involved in anthocyanin biosynthesis showed higher expression levels in purple lines after low-temperature induction. Interestingly, a R2R3-MYB transcription factor (TF) gene ‘BrMYB2’ and a basic-helix-loop-helix (bHLH) regulatory gene ‘BrTT8’ were highly up-regulated in purple lines after low temperature induction, and two negative regulatory genes ‘BrMYBL2.1’ and ‘BrLBD38.2’ were up-regulated in the white line. BrMYB2 and BrTT8 may play important roles in co-activating the anthocyanin structural genes in purple head Chinese cabbage after low-temperature induction, whereas down-regulation of BrMYB2 and up-regulation of some negative regulators might be responsible for white head phenotype formation. Data presented here provide new understanding into the anthocyanin biosynthesis mechanism during low temperature exposure in Brassica crops.

“…leaf and fruit skin) in response to cold and light stresses has been reported (Sivankalyani et al, 2016;Bi et al, 2018). In Begonia leaves, elevation in transcript levels of the anthocyanin biosynthesis genes and as a consequence accumulation of anthocyanin was detected following six days of co-exposure to low temperature and light (300 mmol m −2 s −1 ), while no increase in transcript levels of the anthocyanin biosynthesis genes and anthocyanin level was detected in plants exposed to the same condition and treated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea (inhibitor of light mediated anthocyanin accumulation) or in plants exposed to 25/15°C (day/night) and 300 mmol m −2 s −1 light intensity (Bi et al, 2018). These findings are indicative of the production of anthocyanins possibly in response to light under low temperatures as protectants against excessive ROS production and subsequent chilling injury.…”

Postharvest Spectral Light Composition Affects Chilling Injury in Anthurium Cut Flowers

et al. 2020

The effect of the lighting environment during postharvest storage of ornamentals has largely been neglected in previous research. Anthurium is a cold-sensitive species originating from tropical climates and is widely cultivated all around the world for its colorful spathes. To investigate the effects of light spectrum on the performance of Anthurium cut flowers under cold storage, two cultivars [Calore (red spathe) and Angel (withe spathe)] were placed at low temperature (4°C), either in darkness (D) or under different light spectra [red (R), blue (B), 70:30% red:blue (RB), and white (W)] at an intensity of 125 µmol.m −2 .s −1. In both cultivars, the longest and shortest vase lives were observed in spathes exposed to the R and B spectra, respectively. In both cultivars, electrolyte leakage (EL) of spathe was highest under the B and W spectra and lowest under the R spectrum. The highest rate of flower water loss from the spathes was observed under the B-containing light spectra, whereas the lowest rate of water loss was observed in D and under the R spectrum. Negative correlations were observed between EL and vase life and between anthocyanin concentration and EL for both Anthurium cultivars. A positive correlation was found between anthocyanin concentration and vase life. For both Anthurium cultivars, spectral light composition with higher percentage of B resulted in higher EL and as a result shorter vase life in cut flowers under cold storage condition. The negative effect of the B light spectrum on vase life of Anthurium can be explained through its effect on water loss and on oxidative stress and membrane integrity. The quality of Anthurium cut flowers should benefit from environments with restricted B light spectrum during postharvest handling.

“…As mentioned earlier, anthocyanin production is positively regulated by TFs that activate expression of anthocyanin biosynthesis genes. Several studies have linked low-temperature induction of anthocyanins in several plant species (e.g., snapdragon, grape, maize, red orange, tobacco, and apple) with the upregulation of TFs and anthocyanin biosynthesis genes (Christie et al, 1994 (Ahmed et al, 2015;Ban et al, 2007;Bi et al, 2018;Crifò et al, 2011;Huang et al, 2012;Lin-Wang et al, 2011;Rowan et al, 2009;Steyn et al, 2009;Ubi et al, 2006;Xie et al, 2012;Yamane et al, 2006).…”

Abiotic stresses, such as heat, drought, salinity, low temperature, and heavy metals, inhibit plant growth and reduce crop productivity. Abiotic stresses are becoming increasingly extreme worldwide due to the ongoing deterioration of the global climate and the increase in agrochemical utilization and industrialization. Plants grown in fields are affected by one or more abiotic stresses. The consequent stress response of plants induces reactive oxygen species (ROS), which are then used as signaling molecules to activate stress-tolerance mechanism. However, under extreme stress conditions, ROS are overproduced and cause oxidative damage to plants. In such conditions, plants produce anthocyanins after ROS signaling via the transcription of anthocyanin biosynthesis genes. These anthocyanins are then utilized in antioxidant activities by scavenging excess ROS for their sustainability. In this review, we discuss the physiological, biochemical, and molecular mechanisms underlying abiotic stressinduced anthocyanins in plants and their role in abiotic stress tolerance. In addition, we highlight the current progress in the development of anthocyanin-enriched transgenic plants and their ability to increase abiotic stress tolerance. Overall, this review provides valuable information that increases our understanding of the mechanisms by which anthocyanins respond to abiotic stress and protect plants against it. This review also provides practical guidance for plant biologists who are engineering stress-tolerant crops using anthocyanin biosynthesis or regulatory genes.
