Trace Element Bioavailability Shapes Bacterial Communities and Biological Nitrogen Fixation in Paddy Soils

Biological nitrogen fixation (BNF) is a key nitrogen source in paddy soils, yet its spatial variability remains poorly understood. In this study, we conducted a 90-day 15N2 labeling experiment using soils from seven paddy fields in Zhejiang Province, China, to quantify total nitrogen fixation and fixed-N accumulation i...

Drivers of Biological Nitrogen Fixation in Paddy Soils: Linking Soil Properties, Diazotrophic Communities, and Nitrogen Dynamics

Overall, the findings demonstrated that soil physiochemical properties, micronutrient availability, and microbial community composition interact to regulate BNF in paddy soils.

Multi-granularity Adaptive Hypergraph Representation Learning via Granular-ball

A novel framework called Adaptive Granular Hypergraph Generation (MGHRL) is introduced, which generates hyperedges at multiple levels of granularity through the adaptive splitting of granular-ball, effectively capturing high-order relationships based on the graph's topological structure.
