“…Anthocyanins possess anti-inflammatory, antioxidant, antidiabetic, anticancer, antiobesity, and cardioprotective effects [13]. Cyanidin, one of the anthocyanins, has a flavone skeleton with glucoside and is widely distributed in several vegetables and fruits, red leaf lettuce, black soybean, blackberries, and grapes [14,15]. Several kinds of cyanidin have been reported to have chemotherapeutic activities in humans.…”

Cyanidin, a kind of anthocyanin, has been reported to have chemotherapeutic activities in humans. Human amniotic epithelial cells (hAECs) are considered a potential source of pluripotent stem cells. hAECs have been used as a novel tool in regenerative cellular therapy and cell differentiation studies. In this study, to explore the effects of cyanidin-3-O-glucoside (Cy3G) on hAECs and their mechanisms, we investigated the transcriptomic changes in the Cy3G-treated cells using microarray analysis. Among the differentially expressed genes (Fold change > 1.1; p-value < 0.05), 109 genes were upregulated and 232 were downregulated. Ratios of upregulated and downregulated genes were 0.22% and 0.47% of the total expressed genes, respectively. Next, we explored the enriched gene ontology, i.e., the biological process, molecular function, and cellular component of the 37 upregulated (>1.3-fold change) and 124 downregulated (<1.3-fold change) genes. Significantly enriched biological processes by the upregulated genes included “response to muscle activity,” and the genes involved in this gene ontology (GO) were Metrnl and SRD5A1, which function in the adipocyte. On the other hand, the cell cycle biological process was significantly enriched by the downregulated genes, including some from the SMC gene family. An adipogenesis-associated gene DDX6 was also included in the cell cycle biological process. Thus, our findings suggest the prospects of Cy3G in modulating adipocyte differentiation in hAECs.

“…Prohydrojasmon, which is a synthetic JA derivative, has been used as a bio-stimulant to increase anthocyanin accumulation in crops [27]. Although PDJ is commercially available as a plant growth regulator useful for enhancing the coloration of various fruits, such as apple and grape, its mechanism of action has not been comprehensively characterized.…”

“…Specifically, it has been applied to enhance mango and red pear fruit coloration [25,26]. In our study, lettuce and komatsuna grown under artificial light were treated with several PDJ concentrations, which enhanced the production of some phenolics, polyphenols, and anthocyanins in lettuce leaves [27]. However, the precise mechanisms underlying PDJ-induced phenolic production in red leaf lettuce remain unclear.…”

Prohydrojasmon (PDJ) is a synthetic jasmonate derivative that is primarily used as a growth regulator, but its mechanism of action is unclear. In this study, we elucidated the effects of PDJ on phytochemical production in red leaf lettuce. The PDJ treatments promoted the accumulation of phenolic compounds in aerial plant parts. An LC-MS analysis revealed that these accumulated compounds were identified as cyanidin-3-O-glucoside, cyanidin-3-O-(6″-O-malonyl)-glucoside and cyanidin-3-O-(6″-O-malonyl)-glucoside methyl ester. The abundance of these compounds in lettuce extracts increased significantly in response to the PDJ treatment. Additionally, the LC-MS analysis also identified the accumulated phenolic compounds in the extracts of PDJ-treated lettuce, including caffeoyltartaric acid, chlorogenic acid, caffeoylmalic acid, chicoric acid, and dicaffeoylquinic acid. Gene expression analyses indicated the PDJ treatments upregulated the expression of PAL, F3H, and ANS genes in lettuce. These results suggest that PDJ treatments enhance the expression of genes involved in the synthesis of anthocyanins and phenolic compounds, resulting in an increase in the quantities of these compounds, which reportedly have various functions affecting human physiology.

“…PDJ also induces defense responses against common armyworm in corn (Mandour et al, 2013). Effects of PDJ on phenolic compounds, anthocyanin accumulation, and antioxidant activity in komatsuna and lettuce were reported (Azis et al, 2020). We previously reported that PDJ is a growth regulator that prevents shoot and root growth in both indica and japonica rice cultivars (Chiba & Morino, 2018;Morino et al, 2020).…”

Prohydrojasmon (PDJ), a synthetic derivative of the plant hormone jasmonic acid, has been identified as a plant growth regulator used in various fruit and rice seedlings. In this study, we demonstrate the inhibition of transpiration by PDJ in the indica rice cultivar cv. Takanari compared with commercially available microcrystalline and paraffin wax agents in a greenhouse. Microcrystalline and paraffin wax agents inhibited approximately 30%-50% transpiration 3 h after application, and the inhibition lasted for seven days after treatment, depending on the concentration and the agent used. In contrast, PDJ inhibited approximately 40%-80% transpiration compared with control 0.5 h after treatment, and the effect lasted for one day. However, the effect almost disappeared 7 days after treatment. Thus, PDJ affects transpiration differently than commercially available products and could be used to lower excess transpiration in rice, specifically when an early, transient, and reversible inhibition is needed.
