“…Kuo et al (2015) planted Aquilaria agallocha seedlings under different light conditions and found that red light significantly enhanced the contents of cucurbitacin E and I in this species. Similarly, Wang et al (2018) revealed that red light enhances the production of gypenoside and upregulates the expression of squalene synthase (SS) and squalene epoxidase (SE) genes in Gynostemma pentaphyllum. Chen et al (2018) reported that red and blue light irradiation dramatically changes the accumulation of tanshinones in S. miltiorrhiza hairy roots; red light treatment upregulated the expression of SmHMGR, SmDXS2, SmDXR, SmGGPPS, SmCPS, and CYP76AH1 genes and increased the content of tanshinone II A by 1.4-fold compared with the control, whereas blue light remarkedly suppressed tanshinone II A biosynthesis and downregulated the expression of key tanshinone II A biosynthesis genes.…”

Secondary metabolites (SMs) found in medicinal plants are one of main sources of drugs, cosmetics, and health products. With the increase in demand for these bioactive compounds, improving the content and yield of SMs in medicinal plants has become increasingly important. The content and distribution of SMs in medicinal plants are closely related to environmental factors, especially light. In recent years, artificial light sources have been used in controlled environments for the production and conservation of medicinal germplasm. Therefore, it is essential to elucidate how light affects the accumulation of SMs in different plant species. Here, we systematically summarize recent advances in our understanding of the regulatory roles of light quality, light intensity, and photoperiod in the biosynthesis of three main types of SMs (polyphenols, alkaloids, and terpenoids), and the underlying mechanisms. This article provides a detailed overview of the role of light signaling pathways in SM biosynthesis, which will further promote the application of artificial light sources in medicinal plant production.

“…The habitat of medicinal plants will be significantly reduced or severely migrated (Rana et al, 2020; Shen et al, 2021), posing a serious threat to the sustainable use of medicinal plants. Therefore, it is of great significance to study the response of plants to climate change for the protection (Gupta et al, 2021; Zhang et al, 2000, 2019).…”

“…Leonurus japonicus (on the top left of Figure 1) is a traditional Chinese medicinal plant. Its fresh or dry aboveground parts can be made into a medicine, which has the effects of regulating menstruation, diuresis, and swelling; removing blood stasis; promoting blood circulation and hemostasis; and preventing miscarriage (Wang et al, 2022; Zhang et al, 2000). It was used as a gynecological drug in traditional Chinese medicine during past dynasties, and the market demand is great (Jiang, 2009).…”

Leonurus japonicus Houtt. is a traditional Chinese medicinal plant with high medicinal and edible value. Wild L. japonicus resources have reduced dramatically in recent years. This study predicted the response of distribution range of L. japonicus to climate change in China, which provided scientific basis for the conservation and utilization. In this study, 489 occurrence points of L. japonicus were selected based on GIS technology and spThin package. The default parameters of MaxEnt model were adjusted by using ENMeva1 package of R environment, and the optimized MaxEnt model was used to analyze the distribution of L. japonicus. When the feature combination in the model parameters is hing and the regularization multiplier is 1.5, the MaxEnt model has a higher degree of optimization. With the AUC of 0.830, our model showed a good predictive performance. The results showed that L. japonicus were widely distributed in the current period. The maximum temperature of warmest month, the min temperature of coldest month, the precipitation of wettest month, the precipitation of driest month, and altitude were the main environmental factors affecting the distribution of L. japonicus. Under the three climate change scenarios, the suitable distribution area of L. japonicus will range shift to high latitudes, indicating that the distribution of L. japonicus has a strong response to climate change. The regional change rate is the lowest under the SSP126‐2090s scenario and the highest under the SSP585‐2090s scenario.

“…Light quality during seedling development influences the morphology of the plant (Li et al, 2021), and regulates gene expression and metabolism in plants (Dong et al, 2018). Wang et al (2018b) indicated that light has a significant effect on enzyme activities in the medicinal plant Gynostemma pentaphyllum. Being a sciophilous plant, T. hemsleyanum is commonly cultivated as undergrowth vegetation.…”

Tetrastigma hemsleyanum is a traditional Chinese medicine herb, commonly used for its anti-inflammatory and antitumor properties. Flavonoids are the main functional constituents of T. hemsleyanum, and their production in the herb is affected by light quality. T. hemsleyanum is a shade-loving plant and is usually covered by black shade nets during cultivation. However, there are only a few studies on the effects of using color films on growth and flavonoid synthesis in T. hemsleyanum. In this study, we measured the influence of five different color films on growth indexes—sugar, soluble amino acid, soluble protein, and flavonoid content—and flavonoid-synthesizing enzyme activities in T. hemsleyanum. The films used were colorless plastic film as the control group (CK-W), red film (RF), yellow film (YF), green film (GF), and blue film (BF). BF promoted plant growth and increased yield, as evidenced by the highest growth indexes, soluble amino acid content, and chalcone isomerase (CHI) enzyme activity. RF increased the content of secondary metabolites, thereby enhancing herb quality, as evidenced by the highest phenylalanine ammonia lyase (PAL) activity and increased flavonoid content.
