“…Wang et al investigated the correlation between ginsenoside content in 15 tissues and the expression of six ginsenoside biosynthesis-related genes [31]. Other studies have mainly examined the effects of relevant enzymes on saponin accumulation and the relationship between saponin biosynthesis regulatory networks and saponin accumulation [24][25][26][32][33][34][35][36][37][38][39][40][41]. Thus, investigators have examined saponin biosynthesis at macro, micro, and local mesoscopic levels.…”

Ginseng, a valuable Chinese medicinal herb, is renowned worldwide for its effectiveness in alleviating certain conditions and promoting overall health. In this study, we performed weighted gene co-expression network analysis (WGCNA) on the accumulation of essential saponins under the influence of 13 essential environmental factors (including air temperature, air bottom temperature, surface mean temperature, soil temperature, surface shortwave radiation, soil moisture, soil water content, rainfall, total precipitation, elevation, soil type, soil pH, and soil water potential). We identified a total of 40 transcript modules associated with typical environmental factors and the accumulation of essential saponins. Among these, 18 modules were closely related to the influence of typical environmental factors, whereas 22 modules were closely related to the accumulation of essential saponins. These results were verified by examining the transcriptome, saponin contents, environmental factor information and the published data and revealed the regulatory basis of saponin accumulation at the transcriptome level under the influence of essential environmental factors. We proposed a working model of saponin accumulation mediated by the transcriptional regulatory network that is affected by typical environmental factors. An isomorphic white-box neural network was constructed based on this model and the predicted results of the white-box neural network correlated with saponin accumulation. The effectiveness of our correlation-directed graph in predicting saponin contents was verified by bioinformatics analysis based on results obtained in this study and transcripts known to affect the biosynthesis of saponin Rb1. The directed graph represents a useful tool for manipulating saponin biosynthesis while considering the influence of essential environmental factors in ginseng and other medicinal plants.

“…Tea saponin, a complex pentacyclic triterpenoid consisting of saponins, organic acids, and sugar bodies, is abundant in C. sinensis and CSO (Liu, Geng, et al., 2022). The seeds of tea tree ( C. sinensis ) contain about 11%–15% of saponin.…”

“…The phenolic extract of camellia seed oil has been shown to boost the activities of glutathione peroxidase and superoxide dismutase in vivo, as well as the antioxidant capacity (101.05 ± 6.70 μmol QE/100 g of oil) and free radical scavenging. It can help lower malondialdehyde levels and increase organ index (Liu, Zhu, et al., 2022). A high‐fat diet rich in camellia oil was more successful in lowering LDL cholesterol and serum total cholesterol levels than a high‐fat diet rich in soybean oil (Chou et al., 2018).…”

Woody edible oils are a type of vegetable oil. Woody edible oils like olive oil have greater quantities of unsaturated fatty acids (UFAs), particularly essential FAs, as well as vitamin E, phytosterols, and other nutrients that are becoming more vital in human health. As a result, finding high‐quality woody oil resource plants is critical to ensuring enough edible oil supply. As six novel woody crops, Paeonia suffruticosa, Plukenetia volubilis, Acer truncatum, Olea europaea, Camellia sinensis, and Camellia oleifera are characterized by high oil production, widespread cultivation, adaptability, and various active ingredients. The six woody crop oils contain UFAs (e.g., α‐linolenic acid, oleic acid, and linoleic acid), vitamin E, polyphenols, phytosterols, and so forth. The presence of these active ingredients confers anti‐inflammatory, antioxidant, cholesterol and lipid metabolism regulating, blood lipid lowering, immune boosting, memory improving, intestinal flora regulating, and other properties to the oils, which are beneficial to body health. This article examined in depth the seed resources, FA composition, active component kinds, active ingredient efficacy mechanism, and physiological impacts of these six novel woody crop oils. These developments lay a solid platform for further study and development of these woody oil crops.
