“…The soil characteristics has an important influence on the AMF community, and the analysis of Heatmap (Figure 7) indicated that soil physicochemical properties had different effects on different genera of AMF. Glomus, as the dominant genus, was most affected by soil physicochemical properties and most genera were affected by soil factors, in agreement with some studies (Xu et al, 2017;Kim et al, 2022), explaining to some extent the differences in AMF communities between different altitudes. It further demonstrates that soil factors have an important influence on AMF community structure and diversity.…”

IntroductionArbuscular mycorrhizal fungi (AMF) perform a vital role in terrestrial ecosystems.MethodsTo investigate the diversity of AMF communities on the western slope of Helan Mountain at different altitudes and their influence factors, high-throughput sequencing was used to study the structure and diversity of soil AMF communities under different environments and their interrelationships between AMF and environmental factors.ResultsThe results revealed that there were significant differences (p < 0.05) in the physical and chemical properties of the soil along the different altitudes. A total of 1,145 OTUs were obtained by high-throughput sequencing, belonging to 1 phylum, 4 class, 6 orders, 13 families, 18 genera and 135 species, with the dominant genus being Glomus, which accounted for 75.27% of the relative abundance of the community. Soil AMF community structure was shown to be variable at the generic level according to NMDS analysis. Correlation analysis showed that soil pH, water content (WC), organic matter (OM), available K, available P and N were significantly correlated with AMF community diversity and species abundance (p < 0.05, p < 0.01). Based on redundancy analysis (RDA) and Monte Carlo test results, soil pH, WC and OM had highly significant effects (p < 0.01) on AMF community diversity and species abundance.DiscussionThis study investigates the relationship between AMF community structure and diversity and soil physicochemical properties at different elevations on the western slope of Helan Mountain, which is of great significance to the study of the Helan Mountain ecosystem.

“…Our ndings suggest that wheat grain yield can be explained by AMF OTU composition, suggesting that AMF might play important roles in wheat grain formation. In agroecosystems, AMF can drive soil nutrient cycling to support crop growth(Kim et al 2022;Sheteiwy et al 2021a;Sheteiwy et al 2021b). A similar nding also was con rmed by meta-analysis, which suggests that AMF can promote grain crop yield(Zhang et al 2019).…”

Rational weed control in arable land is a key contributor to food security and sustainable agricultural development. However, little is known about how weed control practices affect the root-associated arbuscular mycorrhizal fungi (AMF), especially in rice-wheat cropping systems. Here, the effects of different weed control measures on AMF community structure, wheat yield and soil properties were determined based on a long-term weed control experiment established since 2001 in a rice-wheat annual double cropping system. The weed control treatments include: (ⅰ) control (CK): No weeding; (ⅱ) manual weeding + herbicide application (MH); (ⅲ) Hindering seeds dispersed from water + herbicide application (WaH); (ⅳ): Hindering seeds dispersed from water + manual weeding (WaM); (ⅴ) Hindering seeds dispersed from water + manual weeding + herbicide application (WaMH). Results demonstrated that weed control markedly affected soil properties, shifted AMF community structure (diversity and composition), and notably increased wheat yield by 52.6%-62.2% compared with CK. The values of Pielou evenness index, Shannon-Weiner index and Simpson’s index were significantly lower under MH compared with CK. The Mantel test analysis indicated that AMF diversity was dominantly controlled by both total nitrogen and soil organic carbon. Similarly, AMF composition was markedly affected by soil water content, total nitrogen, nitrate nitrogen, ammonium nitrogen, and microbial biomass nitrogen. Mantel test also revealed that wheat yield was significantly correlated to AMF composition and Pearson correlation analysis also showed that some key indicator taxa were significantly correlated with wheat yield, suggesting that the composition of AMF community might play an important role in wheat yield formation. In addition, redundancy analysis (RDA) showed that soil properties and wheat yield were closely related to AMF community characteristics. Taken together, our findings suggest that weed control can mediate the relationships among soil quality, AMF community and wheat yield, providing valuable guidance for integrated weed management in the Yangtze River basin regions in China.

“…Bacterial groups represented by nitrogen and phosphorus metabolism may be the core members to maintain the stability of soil microbial communities. Arbuscular mycorrhizal fungi (AMF) are multifunctional symbionts with important ecological significance for most terrestrial plants ( Gorzelak et al, 2017 ; Gu et al, 2020 ; Jiang et al, 2020 ; Zhang et al, 2020 ; Kim et al, 2022 ). AMF can use fungal hyphae to obtain soil water and nutrients such as phosphorus (P), nitrogen (N), and trace elements for plant absorption ( Bulgarelli et al, 2013 ; Pellegrino et al, 2019 ; Jiang et al, 2020 ).…”

Drought is the most prevalent environmental stress in crop production, posing a significant danger to food security. Microorganisms in the crop root zone affect crop growth and development, enhance effective nutrient use, and resist adversity hazards. To analyze the changes and functional differences of root space microbial (endosphere-rhizosphere-bulk soil) communities in spring wheat under drought stress. In this study, the root, rhizosphere, and bulk soil of the drought-tolerant group (DTG, three varieties) and drought-sensitive group (DSG, three varieties) were collected. The control (CK, 25–28%), moderate drought (MD, 15–18%), and severe drought (SD, 9–12%) were analyzed by high-throughput sequencing and bioinformatics. The results showed significant differences in the diversity of Bacteria and Fungi in the root space of spring wheat under drought stress (P < 0.05), with the drought-tolerant group exhibiting higher microbial diversity. The microbial community change in spring wheat root space was mainly determined by the niche differentiation of endosphere, rhizosphere, and bulk soil and declined from endosphere to bulk soil due to drought. The antagonism between microbial and root-space species increased, and the community’s complexity and stability deteriorated. Enriching drought-resistant preference groups like Actinobaciota, Variovorax, Streptomyces, and Conocybe altered the structure and function of the microbial community in the root space of spring wheat. Spring wheat’s root space Bacteria and Fungi have different strategies to respond to drought.
