Hotspots of enzyme activities reflect micro-scale heterogeneity in nutrient mobilization in paddy soils - Plant and Soil Background and aims While intensive fertilization has wide-ranging impact on microbial communities, its effects on microbial recolonization of soil niches and associated enzyme activities as well as hotspots distribution remain underexplored. Methods Using soil zymography and high-throughput sequencing, we investigated the hotspots and activities of C-, N- and P-acquiring hydrolases, as well as bacterial community dynamics across hotspots, coldspots, and root endosphere within rice rhizosphere in sterilized and non-sterilized soils following NPK fertilization. Results Bacterial community reassembly after sterilization was primarily governed by compartment niches rather than by fertilization, although fertilization accelerated bacterial recovery by increasing diversity and network complexity. Specifically, the dominant taxa and major contributor of genes encoding hydrolases in the rhizosphere of non-sterilized soil shifted from Actinomycetota (K-strategists) to Pseudomonadota and Bacillota (r-strategists). In contrast, root endosphere communities had greater resilience during recolonization and likely supported rice growth by expanding enzyme hotspots area. Higher enzyme activities in hotspots, compared to coldspots, correlated strongly with increased bacterial network complexity, and less with differences in diversity and overall community composition. Fertilization triggered a trade-off between enzyme activities and hotspots area, with increased activities for β-glucosidase and leucine aminopeptidase but reduced hotspots area, whereas acid phosphatase had the opposite trend. Conclusion The trade-offs between enzyme activities and hotspots area highlight the micro-scale spatial heterogeneity in nutrient mobilization in paddy soils, suggesting adaptive strategies that plants and microorganisms use to regulate nutrient investment. These findings provide valuable insights for optimizing fertilization management to accelerate microbial processes and enzyme-mediated nutrient cycling. Graphical Abstract

Microbial Physiological Adaptation to Biodegradable Microplastics Drives the Transformation and Reactivity of Dissolved Organic Matter in Soil The turnover of dissolved organic matter (DOM) in soil regulated by biodegradable microplastics (MPs) has garnered much attention due to its profound impact on the storage and stability of soil organic matter. However, the transformation and reactivity of plant-derived and microbially derived DOM by microorganisms adapted to biodegradable MPs, and the involved microbial physiological processes, remain nearly unknown. Here, we added virgin and aged polylactic acid (PLA) and polyhydroxyalkanoate (PHA) to agricultural soils and incubated for 56 days. Using stable isotope techniques, reactomics, and metagenomics, we found that the addition of both virgin and aged PLA induced hydroxylation, demethylation, and dehydrogenation of lignin-derived DOM, resulting in a 3-fold increase in their oxidation degree. PLA activated the enzymatic pathway for lignin-derived DOM decomposition and downregulated genes involved in bacterial anabolism, such as those related to protein, amino sugar, and peptidoglycan biosynthesis. In contrast, PHA increased the content of microbially derived DOM compounds such as proteins and amino sugars by 2.1-fold relative to the control with peptide chain elongation. PHA resulted in the degradation of lignin-derived DOM into pyruvate and acetyl-CoA, accelerated bacterial ATP synthesis, the de novo biosynthesis of proteins and peptidoglycan, and cell renewal and death, thereby increasing PHA- and soil organic matter-derived microbial necromass carbon. Our study provides new insights into the impact of biodegradable MPs on soil DOM transformation and underscores the importance of the microbial physiological processes involved.
