“…For example, it has been shown that root exudates (oleamide, hexadecanamide, ethanolamine, etc.) act as a source of carbon and nitrogen, and their release and accumulation enhance competition between pathogens and other microorganisms and hinder healthy plant growth ( Miao et al, 2023 ).…”

Root exudates contain a complex array of primary and specialized metabolites that play important roles in plant growth due to their stimulatory and inhibitory activities that can select for specific microbes. In this study, we investigated the effects of different root exudate concentrations on the growth of ginseng (Panax ginseng C. A. Mey), ginsenoside levels, and soil fungal community composition and diversity. The results showed that low root exudate concentrations in the soil promoted ginseng rhizome biomass and ginsenoside levels (Rg1, Re, Rf, Rg2, Rb1, Ro, Rc, Rb2, Rb3, and Rd) in rhizomes. However, the rhizome biomass and ginsenoside levels gradually decreased with further increases in the root exudate concentration. ITS sequencing showed that low root exudate concentrations in the soil hardly altered the rhizosphere fungal community structure. High root exudate concentrations altered the structure, involving microecological imbalance, with reduced abundances of potentially beneficial fungi (such as Mortierella) and increased abundances of potentially pathogenic fungi (such as Fusarium). Correlation analysis showed that rhizome biomass and ginsenoside levels were significantly positively correlated with the abundances of potentially beneficial fungi, while the opposite was true for potentially pathogenic fungi. Overall, low root exudate concentrations promote the growth and development of ginseng; high root exudate concentrations lead to an imbalance in the rhizosphere fungal community of ginseng and reduce the plant’s adaptability. This may be an important factor in the reduced ginseng yield and quality and soil sickness when ginseng is grown continuously.

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…He et al (2009) reported that the presence of fungal pathogens in the soil causes replanting disease of American ginseng. The solution to this problem according to the research of Miao et al (2023) is to use ginsenosides as allelopathic growth stimulants of fungal pathogens in the rhizosphere. In addition, other studies have also reported that ginsenosides reduce soil-borne diseases.…”

In a monocropping pattern for the crop domestication process, the interspecific and intraspecific interaction modes can be changed. In domesticated crops, the intraspecific interactions may have detrimental effects. Moreover, soil‐borne diseases in consecutive monocropped medicinal crops can be a critical challenge that has been difficult to solve. This study has been conducted to evaluate the effect of monoculture and intercropped cultivation on soil‐borne diseases caused by root secretions in American ginseng. The results of the correlation analysis showed that the polyethylenes in the roots had a more negative correlation with the occurrence of soil‐borne diseases than ginsenosides. Therefore, polyethylenes can be considered as an important factor in replanting failure of American ginseng. Furthermore, polyethylenes were able to remain in the soil and have a greater impact on the incidence of soil‐borne diseases than ginsenosides.
