In forests, fungal sporocarps house the diverse fungicolous fungi; however, relationships of and associated communities are rarely explored in agroecosystems. a corn field near Gongzhuling City, Jilin Province, China, we found an epigeous sporocarp with agaricoid morphology that could grow next to living plants. Using PacBio metabarcoding combined updated bioinformatic pipeline, surveyed community profile along its cap, rhizomorph hyphosphere soil at much-improved taxonomic resolution. We identified sporocarp, high probability, as Agrocybe dura, this mushroom was significantly negatively correlated Trichoderma hamatum T. harzianum co-occurrence network. Fungal diversity habitat higher than cap habitats. Consistent pattern diversity, node number, edge network diameter average degree were other However, both negative positive cohesion Moreover, z-c plot A. dura only hub, linking multiple species. The results give us glimpse ecological relevance saprobic mushrooms across extensive northeastern black region China. Our findings will aid assessment forecasting hotspots their fertility 'Golden Corn Belt' northeast

Abstract. Understanding the mechanisms of plant-derived carbon (C) and nitrogen (N) transformation stabilization in soil is fundamental for predicting capacity to mitigate climate change support other functions. The decomposition plant residues particulate organic matter (POM) contributes formation mineral-associated (on average more stable) (MAOM) soil. MAOM formed from binding dissolved (ex vivo pathway) or microbial necromass bioproducts (in minerals metal colloids. Which these two (SOM) pathways important under which conditions remains an open question. To address this question, we propose a novel diagnostic model describe C N dynamics as function POM decomposition. Focusing on relations among compartments (i.e., modeling phase space) rather than time trajectories allows isolating processes underlying stabilization. Using combination with database 36 studies residue were tracked into MAOM, found that predominantly fueled by produced microbes decomposing POM. relevance pathway higher clayey soils but lower C-rich N-poor added residues. Overall, our space proved be sound tool mechanistic investigation supported current understanding critical role both mineral soils.

Conservation tillage (CT) is an important agronomic measure that facilitates soil organic carbon (SOC) accumulation by reducing disturbance and plant residue mulching, thus increasing crop yields, improving fertility achieving C neutrality. However, our understanding of the microbial mechanism underlying SOC fraction under different practices still lacking. Here, a 6-year in situ field experiment was carried out to explore effects CT traditional (CK) on fractions eolian sandy soil. Compared with CK, increased particulate OC (POC) content 0-30 cm layer mineral-associated (MAOC) 0-20 layer. Moreover, type depth had significant influences bacterial, fungal protistan community compositions structures. The co-occurrence network divided into 4 ecological modules, module 1 exhibited correlations POC MOC contents. After determining their topological roles, we identified keystone taxa network. results indicated most common bacterial may result loss due low use efficiency, while specific (Cephalotrichum) (Cercozoa) species could facilitate promoting macroaggregate formation predation. Therefore, increase fungi protists, as well reduction bacteria, drove function, which turn promoted sequestration CT. These strengthen functions accrual fractions, contributes development conservation agriculture Northeast China Plain.

Crop residue decomposition is an important part of the carbon cycle in agricultural ecosystems, and microorganisms are widely recognized as key drivers during this process. However, we still know little about how nitrogen (N) input rhizosphere effects from next planting season impact straw-decomposing microbial communities. Here, combined amplicon sequencing DNA-Stable Isotope Probing (DNA-SIP) to explore these through a time-series wheat pot experiment with four treatments: 13C-labeled maize straw addition or without N application (S1N1 S1N0), no (S0N1 S0N0). The results showed that significantly reduced soil alpha diversity early stages. Straw changed beta increased absolute abundance all Growing plants straw-amended further bacterial diversity, weakened straw-induced changes fungal later In contrast, could only increase bacteria fungi while having effect on diversity. SIP-based taxonomic analysis indicated dominant phyla were Actinobacteria Proteobacteria, overrepresented genera belonging Vicinamibacteraceae Streptomyces. Key dominated by Ascomycota, Penicillium Aspergillus. microorganisms; however, was effect. Overall, our study identified demonstrated they exhibited opposite responses

Microbial-driven N turnover is important in regulating fertilizer use efficiency through the secretion of metabolites like glycolipids. Currently, our understanding potential glycolipids to partially reduce and effects on crop yield still limited. Here, a three-year situ field experiment was conducted with seven treatments: no fertilization (CK); chemical N, phosphorus potassium (NPK); NPK plus (N+PKT); PK 10% (0.9 N+PKT), 20% (0.8 30% (0.7 100% (PKT) reduction. Compared NPK, 0–20% reduction did not significantly maize yields, also increased uptake by 6.26–11.07%, but significant changes grain or straw uptake. The resorption under 0.9 N+PKT greater than that while apparent utilization rates partial factor productivity were those NPK. Although led additional labor input costs, compared it had net economic benefit. Our study demonstrates for using agroecosystem management provides theoretical support optimizing strategies.
