However, microbes involved as well as the underlying mechanisms responsible for the observed effect remain unclear. Here we identified active MOB at (circum-) atmospheric CH4 concentrations in agricultural soils amended with green compost, and investigated three complementary hypotheses: (i) atmospheric CH4 consumption is driven by highly activated, flush-feeding MOB; (ii) stimulation of internal CH4 production which fuels flush-feeding methanotrophic activity; and (iii) increased availability of H2 that can serve as additional energy source for mixotrophic methanotrophy. First, we showed that MOB previously activated by exposure to high CH4 concentrations can subsequently oxidize atmospheric CH4 via the flush-feeding lifestyle. Second, no internal CH4 production in soil was observed following compost amendment, likely due to lack of suitable substrates for methanogenesis. Third, provision of elevated H2 concentrations did not affect the concurrent atmospheric CH4 oxidation. Phospholipid fatty acid-stable isotope probing (PLFA-SIP) revealed that four distinct MOB groups were active at (circum-) atmospheric CH4 concentrations in agricultural soils and green compost: Methylocaldum sp., Methylosinus sporium, Methylocystis sp./Methylosinus trichosporium, and USCα. These findings enhance our understanding of methanotroph ecology and can be used to craft more effective strategies of creating \"climate-smart\" soils.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We still know little about whether such effects similarly persist across life stages between different species. In particular, it is unclear if the bacterial communities of closely interacting species, such as hosts and their endoparasitoids, exhibit similar responses to thermal conditions. We reared two generations of the Melitaea cinxia butterfly and its specialized parasitoid wasp, Hyposoter horticola, at three temperatures in the laboratory (26, 28, and 31°C). We found that the two species harbour different bacterial communities as adults, with the parasitoid exhibiting higher bacterial richness than its host butterfly. When the parental generation of the butterfly was exposed to high temperatures, the F1 generation exhibited increased bacterial richness but a reduced diversity (Shannon index). The opposite effect was observed for its parasitoid, but only for the wasps infected with Wolbachia, which appears sensitive to thermal conditions. Collectively, these results highlight that the bacterial communities of insect hosts and their parasitoids are distinct units, differently susceptible to environmental thermal conditions, particularly to temperatures experienced at the parental generation.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147812813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ecosystems' functionality and well-being of above-ground plant community are all significantly impacted by soil microbes' response to these shifting abiotic stresses. With an emphasis on improving their usefulness in climate-smart agriculture (CSA), we reviewed how soil bacteria and fungi tolerate drought stress and improve plant development under water shortage conditions. This systematic analysis used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to elaborate how microbe-based solutions could be incorporated in CSA. A total of 31 articles satisfied the inclusion criteria. The review demonstrated that soil microbial diversity and abundance are considerably altered by drought stress, improve resilience of plants and soil functionality. There was a further observation of high microbial community in the endosphere, and rhizosphere as compared to bulk soil; a clear indication of plants' potential to facilitate soil microbial assemblages. Evidently, plants under drought conditions exude metabolites that stimulate drought-tolerant microbes; that in-turn promote the plants' tolerance to drought. Accordingly, this remarkable synergy between microbes and plants could help forecast how agroecosystems would function in the face of climate change.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As agriculture shifts from conventional to biodegradable plastics, their impacts on different crop rhizosphere microbiomes considering both total (DNA-derived) and active (rRNA-derived) communities have not been clearly elaborated. We hypothesized that microbiome impacts would be distinct across different plants and polymer types. Maize and strawberry plants were cultivated with 1% MP by soil weight, including two conventional polymers (LDPE, PET) and one biodegradable polymer (PBAT). Strawberry plants increased biomass across all MP treatments, accompanied by greater soil nitrate depletion. MP-induced impacts on soil prokaryotic communities were mostly additive to plant effects, as determined by 16S rRNA amplicon sequence profiling. PBAT stimulated Cupriavidus spp. and members of Saccharimonadales, suggesting a selection of potential polymer-degraders and microbial interactions, independent of plant species and root proximity. In contrast, conventional MPs induced a less selective response with compositional shifts across a greater number of taxa. MP-induced changes were more apparent in rRNA- than DNA-derived profiles, suggesting a profound response of putative active taxa. Together, we demonstrate that plant species and MP type jointly modulate rhizosphere microbial community response to MP pollution, with direct implications for soil biogeochemistry, rhizosphere functioning, and crop performance.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-three qualified metagenome-assembled genomes (MAGs) harboring genes involved in NO3- and/or N2O reduction were recovered from both NO3-- and N2O-supplemented microcosms. Twenty MAGs represent novel taxa. Four MAGs, two of each from NO3-- and N2O-supplemented microcosms, contained nosZ genes indicating N2O consumption potential, however the complete denitrification (i.e. NO3-→N2) gene sets were not detected in these MAGs. Though, N2O production exceeded N2O consumption in NO3--supplemented microcosms at 4°C.

Longitudinal sampling revealed a highly diverse RNA virome spanning 16 viral orders within the kingdom Orthornavirae. Phylogenetic analysis of RNA-dependent RNA polymerase sequences identified 358 viral transcripts representing 213 distinct viral species, of which 199 were likely novel, including several putative new virus families and three orders. No viruses known to be pathogenic to humans or bivalves were detected. While total virome composition showed no strong seasonal patterns, environmental parameters influenced virus abundance within specific viral orders, including the highly abundant Picornavirales, Wolframvirales, Bunyavirales, and Sobelivirales.

To dissect the influence of a plant on its microbiome, repeated cycling of microbiomes can be utilized to enhance functional properties in the enriched microbial communities. We used such a successive cultivation approach for wheat (Triticum aestivum) microbiome under drought conditions and selected lineages for drought resilience and susceptibility, with and without enriching the starting community with a library of bacterial isolates obtained from wheat. Significant differences in the rhizosphere microbiome between selection regimes were confirmed through 16S rRNA gene amplicon sequencing. Notably, replicate lineages of each selection regime showed convergence to similar microbiomes. Specific genera were abundant depending on the selection regimes; Stenotrophomonas under drought resilience, while Rahnella under drought conditions when the strain library was added initially. Applying Stenotrophomonas or Rahnella as single inoculum did not improve drought resilience in wheat. We hypothesize that complex microbiome dynamics take place during successive cultivation, which underscores the importance of considering complex plant-microbiome systems for studying plant stress resilience.

However, priority effects across disparate groups of parasitic organisms are poorly understood despite the wide range of taxonomic groups involved. In California oak woodland, we investigated how priority effects between two insect-parasitic fungi (Metarhizium and Beauveria) influenced emergence of nematodes from insect larvae. Field and laboratory results indicated that both fungi were common, but priority effects prevented them from co-emerging from the same larva. Metarhizium- and Beauveria-infected insects did not differ in the species composition of emerging nematodes, but larvae without fungal emergence had distinct nematode communities, with Oscheius almost always emerging without fungi. Experiments indicated that none of the commonly found nematodes (Acrobeloides, Mesorhabditis, Oscheius, and Rhabditis) were entomopathogenic, but that Oscheius could exclude Beauveria if it arrived early. This time-dependent exclusion was likely caused by a bacterium that Oscheius nematodes carried (Serratia proteamaculans). Together, these findings suggest that fungi enter insects as primary arrivers, while nematodes come as secondary arrivers to exploit fungus-killed insects, with priority effects influencing both groups. We suggest that this system is a promising natural microcosm for understanding priority effects across disparate groups in host-parasite systems.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13089402/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147644727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its enzymes bear primordial traits, including carbon-metal bonds and an abundance of transition metal clusters. Ancient traits can also be reflected in structural folds adopted by the enzymes and the catalytic strategies they employ. Here I show that the most common catalytic strategies used to accelerate reactions in the acetyl-CoA pathway are cofactor-aided catalysis, electrostatic interactions and general acid/base catalysis. Enzymes of the acetyl-CoA pathway are replete with Rossman folds, TIM barrel folds, and alpha-beta plaits. These topologies evolved before the divergence of bacteria and archaea, along with five other catalytic folds of the acetyl-CoA pathway. Rossmann folds and TIM barrels likely underwent rapid diversification early in the history of life. In contrast, over half of the folds in the pathway are weakly diversified folds that emerged only once in the history of life, at the origin of biological CO2 fixation. Ancient metabolic pathways point to enzymes with conserved structural cores, which uncover topologies and catalytic strategies employed at the onset of metabolism.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
