“…In this study, the α diversity of fungi decreased from bulk soil to rhizosphere soil, suggesting allelopathic effects of bamboo root exudates on soil fungi. The fungal community associated with the rhizosphere may therefore be influenced by the host, leading to divergent fungal community characteristics in the different soil compartments (Figure 1A), as supported by findings from other recent studies (Urbina et al, 2018;Qin et al, 2022). However, Kong et al (2020) found that the fungal α diversity in the rhizosphere soil of various maize varieties was higher than that in bulk soil, which could be related to factors such as species specificity and soil substrate (root exudates, cell debris; Nannipieri et al, 2007;Broeckling et al, 2008).…”

Soil fungi play an important role in nutrient cycling, mycorrhizal symbiosis, antagonism against pathogens, and organic matter decomposition. However, our knowledge about the community characteristics of soil fungi in relation to bamboo varieties is still limited. Here, we compared the fungal communities in different soil compartments (rhizosphere vs. bulk soil) of moso bamboo (Phyllostachys edulis) and its four varieties using ITS high-throughput sequencing technology. The fungal α diversity (Shannon index) in bulk soil was significantly higher than that in rhizosphere soil, but it was not affected by bamboo variety or interactions between the soil compartment and bamboo variety. Soil compartment and bamboo variety together explained 31.74% of the variation in fungal community diversity. Soil compartment and bamboo variety were the key factors affecting the relative abundance of the major fungal taxa at the phylum and genus levels. Soil compartment mainly affected the relative abundance of the dominant fungal phylum, while bamboo variety primarily influenced the dominant fungal genus. Network analysis showed that the fungal network in rhizosphere soil was more complex, stable, and connected than that in bulk soil. A FUNGuild database analysis indicated that both soil compartment and bamboo variety affect fungal functions. Our findings provide new insights into the roles of both soil compartments and plant species (including variety) in shaping soil fungal communities.

“…Therefore, from the dual perspectives of biological phenomenon observation and mathematical model fitting, our research highlights that the differential distribution of endophytic fungi in different Ang root parts has a potential shaping effect on the cross-parts distribution pattern of metabolic components. Although external temporospatial factors should be considered, the specific microenvironment, comprising the specific metabolite patterns in different plant parts, may affect the tissue part-specific distribution of endophytic fungi [15,16]. Different tissue parts recruit specific microbial species based on their metabolic components or exert influence through quorum sensing, shaping specific microbial community structures.…”

“…The active components of medicinal plants can affect the assembly of endophytic microbiota and shape the community structure [15]. For example, studies have revealed that triterpenoids from Schisandra chinensis regulate the composition of the endophytic community and promote plant growth and metabolite accumulation [16]. Notably, plants have successfully evolved means of survival, which has involved the secretion of byproducts and selecting endophytic microbiota that are beneficial to themselves as much as possible [17].…”

The three distinct medicinal parts of Angelica sinensis (Oliv.) Diels (Ang) roots are the head, body, and tail (ARH, ARB, and ART, respectively). How endophytic fungi shape the differences in metabolic components among these parts remains unclear. We quantified the distribution of active components and endophytic fungi along the ARH, ARB, and ART and their relationships. Based on the metabolic components and their abundances detected via non-target metabolism, the different medicinal parts were distinguishable. The largest number of dominant metabolic components was present in ART. The difference between ART and ARH was the greatest, and ARB was in a transitional state. The dominant active molecules in ART highlight their effects in haemodynamics improvement, antibacterial, anti-inflammatory, and hormone regulation, while ARH and ARB indicated more haemostasis, blood enrichment, neuromodulation, neuroprotection and tranquilisation, hepatoprotection, and antitumour activities than that of ART. The ARHs, ARBs, and ARTs can also be distinguished from each other based on the endophytic fungi at the microbiome level. The most dominant endophytic fungi were distributed in ART; the differences between ART and ARH were the largest, and ARB was in a transition state, which is consistent with the metabolite distributions. Structural equation modelling showed that the endophytic fungi were highly indicative of the metabolic components. Correlation analysis further identified the endophytic fungi significantly positively correlated with important active components, including Condenascus tortuosus, Sodiomyces alcalophilus, and Pleotrichocladium opacum. The bidirectional multivariate interactions between endophytic fungi and the metabolic components shape their spatial variations along the longitudinal direction in the Ang root.

“…These secondary metabolites can affect the composition and function of the endophytic community [5,6]. Therefore, the underlying relationship between the secondary metabolites released by host plants and endophytic fungal communities deserves more attention.…”

Endophytic fungi in flowers influence plant health and reproduction. However, whether floral volatile organic compounds (VOCs) affect the composition and function of the endophytic fungal community remains unclear. Here, gas chromatography–mass spectrometry (GC–MS) and high-throughput sequencing were used to explore the relationship between floral VOCs and the endophytic fungal community during different flower development stages in Osmanthus fragrans ‘Rixiang Gui’. The results showed that the composition of the endophytic fungal community and floral VOCs shifted along with flowering development. The highest and lowest α diversity of the endophytic fungal community occurred in the flower fading stage and full blooming stage, respectively. The dominant fungi, including Dothideomycetes (class), Pleosporales (order), and Neocladophialophora, Alternaria, and Setophoma (genera), were enriched in the flower fading stage and decreased in the full blooming stage, demonstrating the enrichment of the Pathotroph, Saprotroph, and Pathotroph–Saprotroph functions in the flower fading stage and their depletion in the full blooming stage. However, the total VOC and terpene contents were highest in the full blooming stage and lowest in the flower fading stage, which was opposite to the α diversity of the endophytic fungal community and the dominant fungi during flowering development. Linalool, dihydro-β-ionone, and trans-linalool oxide(furan) were key factors affecting the endophytic fungal community composition. Furthermore, dihydro-β-ionone played an extremely important role in inhibiting endophytic fungi in the full blooming stage. Based on the above results, it is believed that VOCs, especially terpenes, changed the endophytic fungal community composition in the flowers of O. fragrans ‘Rixiang Gui’. These findings improve the understanding of the interaction between endophytic fungi and VOCs in flowers and provide new insight into the mechanism of flower development.
