Abstract Background To investigate microbial communities and their contributions to carbon nutrient cycling along water gradients can enhance our comprehension of climate change impacts on ecosystem services. Results We conducted an assessment communities, metagenomic functions, metabolomic profiles within four ecosystems, i.e., desert grassland (DG), shrub-steppe (SS), forest (FO) marsh (MA) in the Altai region Xinjiang, China. Soil total (TC), nitrogen, NH 4 + , NO 3 - increased linearly, but pH decreased with soil gradients. Microbial abundances richness also moisture except fungi protists being lowest MA. Within prokaryotes, relative Proteobacteria Acidobacteria increased, whereas those Actinobacteria Thaumarchaeota In protists, Basidiomycota Mortierellomycota, Evosea Endomyxa became dominant FO MA, respectively, abundance Cercozoa The β-diversity microbiomes, functioning were linearly distributed gradients, significantly associated factors TC, pH. For metabolic genes related Carbohydrate (CO 2 fixation, Di- oligosaccharides, Fermentation, One-carbon metabolism), Iron (Iron acquisition Vibrio Campylobacter iron metabolism) moisture, while metabolisms Nitrogen (Ammonia assimilation, Denitrification, Nitrosative stress) Potassium (Potassium homeostasis) Additionally, MA harbored most abundant metabolomics dominated by lipids lipid-like molecules (Erucic acid, Hypogeic Kojibiose, etc.), organic oxygen compounds (Maltotetraose, Quinone, Sucrose, Trehalose, certain metabolites showing decline trends such as N'-Hydroxymethylnorcotinine 5-Hydroxyenterolactone. Conclusions Our study suggests that future succession facilitated changes rainfall patterns will alter taxa, functional potential metabolite fractions.

The plant microbiome, found in the rhizosphere, phyllosphere, and endosphere, is essential for nutrient acquisition, stress tolerance, overall health of plants. This review aims to update our knowledge critically discuss diversity functional roles rice as well microbiome engineering strategies enhance biofertilization resilience. Rice hosts various microorganisms that affect cycling, growth promotion, resistance stresses. Microorganisms carry out these functions through nitrogen fixation, phytohormone metabolite production, enhanced solubilization uptake, regulation host gene expression. Recent research on molecular biology has elucidated complex interactions within microbiomes signalling mechanisms establish beneficial microbial communities, which are crucial sustainable production environmental health. Crucial factors successful commercialization agents include soil properties, practical field conditions, genotype. Advances engineering, from traditional inoculants synthetic biology, optimize availability resilience abiotic stresses like drought. Climate change intensifies challenges, but innovations microbiome-shaping genes (M genes) offer promising solutions crop also discusses agronomic implications emphasizing need further exploration M breeding disease traits. Ultimately, we provide an current findings rice, highlighting pathways productivity sustainably while minimizing impacts.

Agricultural plastic mulch enhances crop yields but leads to persistent microplastic contamination in soils. Concurrently, nitrogen (N) fertilization and atmospheric deposition profoundly reshape microbial ecosystems. This study examined the individual interactive effects of polyethylene microplastics (PE, 1% w/w) addition (N, 180 kg ha−1 yr−1) on soil protist communities rape (Brassica napus L.) productivity. High-throughput sequencing soil–plant trait analyses revealed that PE alone reduced water retention biomass while elevating total carbon content, C/N ratios, NH₄⁺-N/NO₃−-N levels. Conversely, N significantly boosted chlorophyll likely through enhanced nutrient availability. Strikingly, combined PE_N treatment exhibited antagonistic interactions; diversity functional group composition stabilized resemble control conditions, under showed no difference from CK (with basal fertilizer only), despite significant reductions alone. Soil dynamics (e.g., SWC ratio) community structure collectively explained 96% variation. These findings highlight potential mitigate microplastic-induced degradation, offering a pragmatic strategy stabilize productivity contaminated agricultural systems. underscores importance balancing management with pollution sustain health global pressures.

The root-associated methanotrophs contribute to N2 fixation and CH4 oxidation in paddy fields under N-limited conditions. However, the impact of nitrogen inputs on N₂ CH₄ by is largely unknown, especially saline-alkali with higher application. This study explored fertilization active diazotrophic methanotrophic communities a field using 15N–N2 13C–CH4 isotope feeding experiments along RNA-based sequencing. 15N 13C showed that oxidation-dependent rate (15N 13C) roots two rice cultivars was significantly than oxidation-independent heterotrophic diazotrophs (only 15N) (SN) environment (P < 0.05). For Kongyu131 rice, ranged from 1.17 4.15 μmol/h/g, while determined be 1.10 3.17 μmol/h/g. In J3 these rates were 7.30 9.22 μmol/h/g 5.76 4.85 respectively Moreover, both salt-alkali tolerant cultivar (9.22 for fixation; 0.09 oxidation) those common (4.15 0.03 0.01). Thus, associated demonstrated improved activities stress presence fertilizer. Even enhanced or without (LN) inputs. amplicon sequencing fertilizer had greater influence differences between cultivars. Further, Methylomonas (type I methanotrophs) dominated (9.8–20.9%) (46.8–80.3%) communities.

Abstract Bioindication, evaluating biological responses to environmental disturbances, is crucial for assessing the ecological status of an ecosystem. While historical bioindication relied on macroscopic organisms, introduction DNA (eDNA) techniques allows application protists without necessity morphological identification. In this study, we propose a novel methodology utilizing Arcellinida, group top predators among protists, as bioindicators freshwater ecosystems. For that purpose, first characterized Arcellinida diversity over 1 year at three different points Lake Sanabria, ancient glacier lake known be subjected anthropogenic disturbances. We compared with undisturbed control site. Second, in other ecosystems generate background test connectivity between them. Results indicate limited and edge effect terrestrial aquatic Disturbed exhibited reduced both specific infraspecific levels, providing valuable insight into recent Arcellinida‐based provides sensitive, accurate easy‐to‐interpret protocol monitoring disturbances It represents tool assessments conservation strategies.
