Effects of Abiotic Stress on Soil Microbiome

International Journal of Molecular Sciences, Journal Year: 2021, Volume and Issue: 22(16), P. 9036 - 9036

Rhizospheric organisms have a unique manner of existence since many factors can influence the shape microbiome. As we all know, harnessing interaction between soil microbes and plants is critical for sustainable agriculture ecosystems. We achieve agricultural practice by incorporating plant-microbiome as positive technology. The contribution this has piqued interest experts, who plan to do more research using beneficial microorganism in order accomplish vision. Plants engage wide range interrelationship with microorganism, spanning entire spectrum ecological potential which be mutualistic, commensal, neutral, exploitative, or competitive. Mutualistic found plant-associated microbial communities assist their host number ways. Many studies demonstrated that microbiome may provide significant advantages plant. However, various conditions (pH, temperature, oxygen, physics-chemistry moisture), environments (drought, submergence, metal toxicity salinity), plant types/genotype, practices result distinct composition characteristics, well its mechanism promote development defence against these stressors. In paper, an in-depth overview how above are able affect structure change below ground interactions. Future prospects will also discussed.

Identification of structural and regulatory cell-shape determinants in Haloferax volcanii

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Feb. 15, 2024

Abstract Archaea play indispensable roles in global biogeochemical cycles, yet many crucial cellular processes, including cell-shape determination, are poorly understood. Haloferax volcanii , a model haloarchaeon, forms rods and disks, depending on growth conditions. Here, we used combination of iterative proteomics, genetics, live-cell imaging to identify mutants that only form or disks. We compared the proteomes with wild-type cells across phases, thereby distinguishing between protein abundance changes specific cell shape those related phases. The results identified diverse set proteins, predicted transporters, transducers, signaling components, transcriptional regulators, as important for determination. Through phenotypic characterization deletion strains, established rod-determining factor A (RdfA) disk-determining (DdfA) required formation respectively. also structural an actin homolog plays role disk-shape morphogenesis, which named volactin. Using imaging, determined volactin’s localization showed its dynamic polymerization depolymerization. Our provide insights into archaeal possible implications understanding evolution morphology regulation domains.

Advancing biomonitoring of eDNA studies with the Anaconda R package: Integrating soil and One Health perspectives in the face of evolving traditional agriculture practices

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(1), P. e0311986 - e0311986

Published: Jan. 16, 2025

Soil health and One Health are global concerns, necessitating the development of refined indicators for effective monitoring. In response, we present Anaconda R Package, a novel tool designed to enhance analysis eDNA data biomonitoring purposes. Employing combination different approaches, this package allows comprehensive investigation species abundance community composition under diverse conditions. This study applied examine impact two types duration fire-fallow cropping systems, using natural forests as reference, on soil fungal bacterial communities in Maré Island (New Caledonia). Condition-specific taxa were identified, particularly pathogenic fungi bacteria, demonstrating importance long-term fallowing efforts. Notably, also revealed potential contributions beneficial microbes, including saprophytes plant-endophyte fungi, suppressing soil-borne pathogens. Over-represented microbial ASVs associated with both plant animal pathogens, those concern human health, identified. underscores maintaining intrinsic balance disease suppression. Importantly, advanced analytical statistical methods offered by should be harnessed comprehensively investigate effects agricultural practice changes within framework. Looking ahead, application method extends beyond realm Health, offering valuable insights into various ecological scenarios.

Association of poultry vaccination with interspecies transmission and molecular evolution of H5 subtype avian influenza virus

Science Advances, Journal Year: 2025, Volume and Issue: 11(4)

Published: Jan. 22, 2025

The effectiveness of poultry vaccination in preventing the transmission highly pathogenic avian influenza viruses (AIVs) has been debated, and its impact on wild birds remains uncertain. Here, we reconstruct movements H5 subtype AIV lineages among vaccinated poultry, unvaccinated birds, worldwide, from 1996 to 2023. We find that there is a time lag viral different host populations were more frequent than those poultry. Furthermore, our findings suggest HA (hemagglutinin) gene lineage circulated predominately Chinese experienced greater nonsynonymous divergence adaptive fixation other lineages. Our results indicate epidemiological, ecological, evolutionary consequences widespread may be linked complex ways much work needed better understand how such interventions affect to, within, birds.

Salt to conserve: a review on the ecology and preservation of hypersaline ecosystems

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2021, Volume and Issue: 96(6), P. 2828 - 2850

Published: July 19, 2021

ABSTRACT When it comes to the investigation of key ecosystems in world, we often omit salt from ecological recipe. In fact, despite occupying almost half volume inland waters and providing crucial services humanity nature, saline are overlooked discussions regarding preservation global aquatic resources our planet. As a result, knowledge biological geochemical dynamics shaping these environments remains incomplete hesitant framing effective protective strategies against increasing natural anthropogenic threats faced by such habitats. Hypersaline lakes, water bodies where concentration exceeds 35 g/l, occur mainly arid semiarid areas resulting hydrological imbalances triggering accumulation salts over time. Often considered ‘exotic siblings’ within family waters, host some most extremophile communities worldwide provide essential habitats for waterbirds many other organisms already water‐stressed regions. These systems highlighted as laboratories, ideal addressing central questions due their relatively low complexity simple food web structures. However, recent studies on biogeochemical mechanisms hypersaline have challenged this archetype, arguing that newly discovered highly diverse characterised specific trophic interactions shaped high levels specialisation. The main goal review is explore current understanding four research questions: ( i ) why lakes unique perspective; ii which biota inhabit how they adapted conditions; iii do protect biodiversity threats; iv scientific tools will help us preserve future? First, focus characterisation ecosystems, illustrate hydrogeochemical regulating environments, outline ecoregions supporting across globe. Second, depict diversity functional aspects taxa found microorganisms plants, invertebrates, upper levels. Next, describe ecosystem discuss possible conservation guidelines. Finally, cutting‐edge technologies can new insights into study ecology. Overall, sheds further light onto understudied largely unrecognised important sources diversity. We perspectives future avenues, advocate should not be taken with ‘a grain salt’.
