“…The structure of the soil microbial community was closely linked with changes in soil physicochemical factors ( Ding et al, 2020 ). In this study, Proteobacteria, Acidobacteria, and Actinobacteria were the dominant soil bacteria in the different treatments ( Figure 2A ), which is consistent with the previous research results ( Shang et al, 2021 ).…”

Soil microorganisms are the key driver of the geochemical cycle in forest ecosystem. Changes in litter and roots can affect soil microbial activities and nutrient cycling; however, the impact of this change on soil microbial community composition and function remain unclear. Here, we explored the effects of litter and root manipulations [control (CK), doubled litter input (DL), litter removal (NL), root exclusion (NR), and a combination of litter removal and root exclusion (NI)] on soil bacterial and fungal communities and functional groups during a 2-year field experiment, using illumina HiSeq sequencing coupled with the function prediction platform of PICRUSt and FUNGuild. Our results showed that litter and root removal decreased the diversity of soil bacteria and fungi (AEC, Shannon, and Chao1). The bacterial communities under different treatments were dominated by the phyla Proteobacteria, Acidobacteria, and Actinomycetes, and NL and NR reduced the relative abundance of the first two phyla. For the fungal communities, Basidiomycetes, Ascomycota, and Mortierellomycota were the dominant phyla. DL increased the relative abundance of Basidiomycetes, while NL and NR decreased the relative abundance of Ascomycota. We also found that litter and root manipulations altered the functional groups related to the metabolism of cofactors and vitamins, lipid metabolism, biosynthesis of other secondary metabolites, environmental adaptation, cell growth, and death. The functional groups including ectomycorrhizal, ectomycorrhizal-orchid mycorrhizal root-associated biotrophs and soil saprotrophs in the fungal community were also different among the different treatments. Soil organic carbon (SOC), pH, and soil water content are important factors driving changes in bacterial and fungal communities, respectively. Our results demonstrate that the changes in plant detritus altered the soil microbial community structure and function by affecting soil physicochemical factors, which provides important data for understanding the material cycle of forest ecosystems under global change.

“…The continuous cropping obstacle caused by the continuous cropping of the soil has increased the obstacles to the soil, which seriously restricts the improvement of crop yield and quality. How to realize the improvement of yellow soil fertility and ease the obstacles of continuous cropping is one of the important problems that need to be solved urgently (Cheng et al, 2020;Ding et al, 2019). At the same time, as the byproduct of the production of Guizhou sauce-avor liquor, the sauce-avored lees has an annual output of about 2 million tons, but the actual treatment of lees is less than 1 million tons per year, and about 50% of the lees are still idle or abandoned (Yang et al, 2019).…”

In order to realize the resource utilization of Guizhou sauce-avor distiller's grains and the improvement of yellow soil fertility, a eld experiment was carried out to study the effects of short-term application of vinasse biochar on soil nutrients and the diversity of fungal community structure by setting ve biochar dosages of 0% (MB 0 ), 0.5% (MB 0.5 ), 1.0% (MB 1.0 ), 2.0% (MB 2.0 ), and 4.0% (MB 4.0 ). The results showed that the application of lees biochar increased the pH, soil organic matter (SOM), total nitrogen (TN), ammonium N (AN), nitrate N (NN), available phosphorus and available potassium of the yellow soil to varying degrees, but decreased the microbial biomass carbon (MBC) and microbial biomass N (MBN) by 12.36%-26.49% and 34.10%-59.95% respectively. The application of lees biochar signi cantly reduced the number of fungal OTUs and community diversity. Compared with MB 0 treatment, the application of lees biochar signi cantly changed the structure of the fungal community. The relative abundances of Mortierellomycota, Basidiomycota, Glomeromycota, and Chlorophyta were all increased in varying degrees, but the relative abundance of Ascomycota was signi cantly reduced by 23.86%-29.06%. At the same time, the application of lees biochar also increased the relative abundance of some functional bacteria, such as Mortierella and Chaetomium, and reduced the relative abundance of some pathogenic bacteria, such as Aspergillus and Fusarium. In addition, the results of redundant analysis showed that SOM, AN and NN were the main environmental factors that affect the change of yellow soil fungal community structure. In summary, the short-term application of lees biochar can increase the nutrient content of soil, change the structure and diversity of soil fungal communities, and also can reduce the relative abundance of some pathogenic bacteria, which can inhibit the growth and reproduction of harmful plant pathogens.

“…The rhizosphere physicochemical properties and C, N, and P-circling enzyme activities were assayed using the methods listed in previous studies ( Zheng et al, 2019 ; Ding et al, 2020a , b ) and the Supplementary Description of Method . Briefly, rhizosphere soil pH was measured with a suspension (soil: water = 1:2.5 w/v); Water content (WC, %) was obtained by oven-drying at 105°C ( Wang et al, 2022 ).…”

“…Briefly, rhizosphere soil pH was measured with a suspension (soil: water = 1:2.5 w/v); Water content (WC, %) was obtained by oven-drying at 105°C ( Wang et al, 2022 ). Rhizosphere C-circling functions were characterized as follows ( Bowker et al, 2013 ; Bastida et al, 2016 ; Luo et al, 2018 ; Ding et al, 2020a ): organic carbon (g kg −1 , OC) was assayed using potassium dichromate volumetric method, β-glucosidase (C-circling enzyme, μmol d −1 g −1 dry soil, βG) was detected using an ELISA test kit (Shanghai Enzyme-linked Biotechnology Co., Ltd., China). Microbial biomass carbon (mg kg −1 , MBC) was determined by the fumigation–extraction method.…”

Microbes, especially abundant microbes in bulk soils, form multiple ecosystem functions, which is relatively well studied. However, the role of rhizosphere microbes, especially rhizosphere rare taxa vs. rhizosphere abundant taxa in regulating the element circling, multifunctionality, aboveground net primary productivity (ANPP) and the trade-offs of multiple functions remains largely unknown. Here, we compared the multiple ecosystem functions, the structure and function of rhizosphere soil bacterial and fungal subcommunities (locally rare, locally abundant, regionally rare, regionally abundant, and entire), and the role of subcommunities in the Zea mays and Sophora davidii sole and Z. mays/S. davidii intercropping ecosystems in subtropical China. Results showed that intercropping altered multiple ecosystem functions individually and simultaneously. Intercropped Z. mays significantly decreased the trade-off intensity compared to sole Z. mays, the trade-off intensity under intercropped S. davidii was significantly higher than under intercropped Z. mays. The beta diversities of bacterial and fungal communities, and fungal functions in each subcommunity significantly differed among groups. Network analysis showed intercropping increased the complexity and positive links of rare bacteria in Z. mays rhizosphere, but decreased the complexity and positive links of rare bacteria in S. davidii rhizosphere and the complexity and positive links of fungi in both intercropped plants rhizosphere. Mantel test showed significant changes in species of locally rare bacteria were most strongly related to nitrogen-cycling multifunctionality, ANPP and trade-offs intensity, significant changes in species of locally rare fungus were most strongly related to carbon-cycling multifunctionality, phosphorus-cycling multifunctionality, and average ecosystem multifunctionality. This research highlights the potential and role of rare rhizosphere microorganisms in predicting and regulating system functions, productivity, and trade-offs.
