“…Phenylacetaldehyde in this study was positively correlated with the bacteria of Gaiellaceae and the fungi of Tausonia , Tuber in this study. Tausonia was reported as a key species in the rhizosphere fungal network of Scutellaria tsinyunensis and was usually found as a soil‐borne pathogen from woody plants (Zuo et al, 2022). Additionally, Gaiellaceae (Bazany et al, 2022; Poudel et al, 2016) and Tuber (Flores et al, 2002) were demonstrated to defend against pathogenic microorganisms and were closely related to plant health.…”

Understanding soil metabolic diversity and the chemical signals that shape rhizosphere microbial activity is important for protecting plants and improving forest productivity. At present, little information is known about the metabolites in the rhizosphere soil of pecan (Carya illinoinensis) plantation. Based on technologies of untargeted metabolomics and high-throughput sequencing, we investigated differences in the metabolic profiles of rhizosphere and bulk soils and the relationship between metabolites and microorganisms in pecan plantations. The results showed that the abundance of metabolites in rhizosphere soil was significantly higher than that in bulk soil (p < 0.05), especially reflected in plant secondary metabolites and lipids. Orientaloside and marmesin rutinoside were significantly enriched in rhizosphere soil metabolites of pecan at three pecan ages (VIP >1, p < 0.05). The linoleic acid and α-linolenic acid metabolic pathways were significantly enriched in the differential metabolic set (p < 0.01). In addition, tryptophan metabolism, starch and sucrose metabolism, and galactose metabolism were also important factors affecting the rhizosphere metabolic spectrum. Differential metabolites between bulk and rhizosphere soils were more closely associated with bacteria than with fungal communities, particularly in young pecans. With the increasing age of pecans, new significant enrichment of plant secondary metabolites such as cyanidin, 3-trans-caffeoyltormentic acid, N-(1-Deoxy-1-fructosyl) serine and piperdia emerged in the rhizosphere soil.3-trans-caffeoyltormentic acid was positively related to Saitozyma and Protoglossum.Phenylacetaldehyde was positively correlated with Gaiellaceae, Tausonia, and Tuber.This study provides new insights into the mechanisms of interaction between pecans and microorganisms.

“…Among the top 20 dominant fungal genera ( Table S23 ), the genus Russula was only detected in AF, while Cladosporium , Microthyrium , and Cladobotryum were only detected in AA. It is reported that some members of Russula are important ectomycorrhizal fungi that play a key role in soil nutrient uptake and cycling [ 46 ]. Also, the genus Cladobotryum has been considered a great potential antifungal resource against fungal phytopathogens [ 47 ], and its secondary metabolites displayed chemical and bioactive diversity [ 48 ].…”

Astragalus is a medicinal plant with obvious rhizosphere effects. At present, there are many Astragalus plants with high application value but low recognition and resource reserves in the northwestern area of Yunnan province, China. In this study, metagenomics was used to analyze the microbial diversity and community structure of rhizosphere soil of A. forrestii, A. acaulis, and A. ernestii plants grown in a special high-cold environment of northwestern Yunnan, China, at different altitudes ranging from 3225 to 4353 m. These microbes were taxonomically annotated to obtain 24 phyla and 501 genera for A. forrestii, 30 phyla and 504 genera for A. acaulis, as well as 39 phyla and 533 genera for A. ernestii. Overall, the dominant bacterial phyla included Proteobacteria, Actinobacteria, and Acidobacteria, while the dominant fungal ones were Ascomycota and Basidiomycota. At the genus level, Bradyrhizobium, Afipia, and Paraburkholderia were the most prevalent bacteria, and Hyaloscypha, Pseudogymnoascus, and Russula were the dominant fungal genera. Some of them are considered biocontrol microbes that could sustain the growth and health of host Astragalus plants. Redundancy analysis revealed that pH, TN, and SOM had a significant impact on the microbial community structures (p < 0.05). Finally, triterpene, flavonoid, polysaccharide, and amino acid metabolisms accounted for a high proportion of the enriched KEGG pathways, which possibly contributed to the synthesis of bioactive constituents in the Astragalus plants.

“…Besides, altitude was the third important environmental factor controlling the distribution of three Fritillaria species, accounting for 24%, 8% and 24.6% overall contribution to F. delavayi , F. taipaiensis and F. wabuensis , respectively. The accumulation of metabolites and nutrients in underground and subaerial organs are influenced by altitude usually interacting with the availability of nutrients, water content 71 , temperature, ultraviolet intensity, CO 2 concentration and UV-B 33 . For instance, the reproductive success of F. delavayi was critically affected by the temperature and ultraviolet intensity, and as a result, F. delavayi was distributed in a narrow altitude area 57 .…”

The Fritillaria species ranked as a well-known traditional medicine in China and has become rare due to excessive harvesting. To find reasonable strategy for conservation and cultivation, identification of new ecological distribution of Fritillaria species together with prediction of those responses to climate change are necessary. In terms of current occurrence records and bioclimatic variables, the suitable habitats for Fritillaria delavayi, Fritillaria taipaiensis, and Fritillaria wabuensis were predicted. In comparison with Maxent and GARP, Biomod2 obtained the best AUC, KAPPA and TSS values of larger than 0.926 and was chosen to construct model. Temperature seasonality was indicated to put the greatest influence on Fritillaria taipaiensis and Fritillaria wabuensis, while isothermality was of most importance for Fritillaria delavayi. The current suitable areas for three Fritillaria species were distributed in south-west China, accounting for approximately 17.72%, 23.06% and 20.60% of China's total area, respectively. During 2021–2100 period, the suitable habitats of F. delavayi and F. wabuensis reached the maximum under SSP585 scenario, while that of F. taipaiensis reached the maximum under SSP126 scenario. The high niche overlap among three Fritillaria species showed correlation with the chemical composition (P ≤ 0.05), while no correlation was observed between niche overlap and DNA barcodes, indicating that spatial distribution had a major influence on chemical composition in the Fritillaria species. Finally, the acquisition of species-specific habitats would contribute to decrease in habitat competition, and future conservation and cultivation of Fritillaria species.
