Soil Nutrient Enrichment Induces Trade‐Offs in Bacterial Life‐History Strategies Promoting Plant Productivity

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Soil nutrient enrichment induces the trade‐offs between bacterial functional potential and growth‐rate potential. Such trade‐offs favor specific plant‐beneficial species and genes, playing a pivotal role in determining plant productivity. These findings enhance the understanding of the microbial responses in agroecosystems to ongoing global ...

Wide Distribution of a Novel pmoA -Like Gene Copy among Type II Methanotrophs, and Its Expression in Methylocystis Strain SC2 [PDF]

Applied and Environmental Microbiology, 2003
ABSTRACT Experiments were conducted to determine if a novel pmoA -like gene ( pmoA2 ) recently discovered in the methane-oxidizing bacterium Methylocystis strain SC2 (P. F. Dunfield, M. Tchawa Yimga, S. D. Dedysh, U. Berger, W. Liesack, and J.

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Marine organic aerosol at Mace Head: effects from phytoplankton and source region variability [PDF]

Atmospheric Chemistry and Physics
Organic aerosol (OA) is recognized as a significant component of particulate matter (PM), yet their specific composition and sources, especially over remote areas, remain elusive due to the overall scarcity of high-resolution online data.

Microbial Community Composition and Function in Jiangsu Oil Reservoir Cores, China

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Shale oil reservoirs meet the basic requirements for microbial growth. Microorganisms, crude oil and water are distributed within the pore spaces of the reservoir formation. In situ microorganisms utilise crude oil for growth and reproduction. ABSTRACT Shale oil reservoirs are typically characterised by elevated temperatures, confined spaces and ...

关于复合外套MOA机械强度计算问题的研究

Gaoya dianqi, 2007
针对电力系统应用广泛的复合外套金属氧化物避雷器（PMOA）机械强度的计算问题,进行了分析研究,并提出了定量分析公式,即采用PMOA顶端的转角θ和挠度f来衡量载荷对避雷器变形量的大小。分析计算结果表明:在载荷一定的情况下,减少PMOA的长度可以明显减小外部载荷对其产生的变形量,从而提高其机械性能。

Critical evaluation of three cryo‐EM structures of particulate methane monooxygenase by quantum refinement

Acta Crystallographica Section D, Volume 81, Issue 11, Page 605-620, November 2025.
We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Different parts of the mussel Gigantidas haimaensis holobiont responded differently to deep‐sea sampling stress

Integrative Zoology, Volume 20, Issue 6, Page 1294-1305, November 2025.
Symbiotic gill and nonsymbiotic mantle of mussel Gigantidas haimaensis responded differently to deep‐sea sampling stress caused by acute environmental changes. Sharply increased transcription factors potentially play key roles in initiating the response of sampled deep‐sea macrobenthos to the sampling stress.

Patterns and geographical drivers for the abundance of CO2-assimilating bacteria, methanotrophs and CO-oxidizing bacteria in agricultural soils across eastern China

Journal of Integrative Agriculture
Microorganisms carrying cbbL, pmoA and coxL genes play crucial roles in regulating soil-atmosphere exchanges of carbon trace gases (CO2, CH4, and CO). However, the geographical distribution patterns of these functional genes in agricultural ecosystems ...

Call for Standardizing Uncaria rhynchophylla as the Sole Origin of Uncariae Ramulus cum Uncis

Phytochemical Analysis, Volume 36, Issue 7, Page 1959-1973, October 2025.
ABSTRACT Background Uncariae Ramulus cum Uncis (URCU) is a widely used traditional Chinese medicine (TCM) for treating neurodegenerative disorders. The Chinese Pharmacopeia recognizes five Uncaria species as authorized botanical sources of URCU; however, there is currently no established quality control method for individual species.
