Diazotrophic Anaeromyxobacter Isolates from Soils

Applied and Environmental Microbiology, Journal Year: 2020, Volume and Issue: 86(16)

Published: June 12, 2020

Anaeromyxobacter is globally distributed in soil environments, especially predominant paddy soils. Current studies based on environmental DNA/RNA analyses frequently detect gene fragments encoding nitrogenase of from various environments. Although the importance as a diazotroph nature has been suggested by culture-independent studies, there no solid evidence and validation genomic culture-based that fixes nitrogen. This study demonstrates harboring genes exhibits diazotrophic ability; moreover, N 2 -dependent growth was demonstrated vitro environment. Our findings indicate nitrogen fixation important for to survive under nitrogen-deficient environments provide novel insight into function , which common bacterium

Metagenomics: A Tool for Exploring Key Microbiome With the Potentials for Improving Sustainable Agriculture

Frontiers in Sustainable Food Systems, Journal Year: 2022, Volume and Issue: 6

Published: June 17, 2022

Microorganisms are immense in nature and exist every imaginable ecological niche, performing a wide range of metabolic processes. Unfortunately, using traditional microbiological methods, most microorganisms remain unculturable. The emergence metagenomics has resolved the challenge capturing entire microbial community an environmental sample by enabling analysis whole genomes without requiring culturing. Metagenomics as non-culture approach encompasses greater amount genetic information than approaches. plant root-associated is essential for growth development, hence interactions between microorganisms, soil, plants to understand improve crop yields rural urban agriculture. Although some these currently unculturable laboratory, metagenomic techniques may nevertheless be used identify their functional traits. A detailed understanding organisms should facilitate improvement sustainable production soil soilless Therefore, objective this review provide insights into study microbiota ecology. In addition, different DNA-based role elaborating microbiomes discussed. As biotechnological potentials unlocked through metagenomics, they can develop new, useful unique bio-fertilizers bio-pesticides that not harmful environment.

Soil pH: a key edaphic factor regulating distribution and functions of bacterial community along vertical soil profiles in red soil of pomelo orchard

BMC Microbiology, Journal Year: 2022, Volume and Issue: 22(1)

Published: Feb. 2, 2022

Abstract Background Soil microbes exist throughout the soil profile and those inhabiting topsoil (0–20 cm) are believed to play a key role in nutrients cycling. However, majority of microbiology studies have exclusively focused on distribution microbial communities topsoil, it remains poorly understood through subsurface (i.e., 20–40 40–60 cm). Here, we examined how bacterial community composition functional diversity changes under intensive fertilization across vertical profiles [(0–20 cm (RS1), (RS2), (RS3)] red pomelo orchard, Pinghe County, Fujian, China. Results Bacterial was determined by 16S rRNA gene sequencing interlinked with edaphic factors, including pH, available phosphorous (AP), nitrogen (AN), potassium (AK) investigate factors that shape along different profiles. The most dominant taxa were Proteobacteria , Acidobacteria Actinobacteria Chloroflexi Crenarchaeota, Bacteriodetes . richness highest RS1 declined increasing depth. distinct patterns found Besides, pH exhibited strong influence (pH ˃AP ˃AN) all depths. relative abundance Proteobacteria, Actinobacteria, Firmicutes negatively correlated while Acidobacteria, Chloroflexi, Bacteriodetes, Planctomycetes, Gemmatimonadetes positively pH. Co-occurrence network analysis revealed topological features weakened depth, indicating more stable RS1. functions estimated using FAPROTAX related metabolic processes, C-cycle, N-cycle, energy production significantly higher compared RS2 RS3, had significant effect these microbes. Conclusions This study provided valuable findings regarding structure orchards, highlighted importance depth shaping population, their spatial ecological functioning.

Actinobacteria–Plant Interactions in Alleviating Abiotic Stress

Plants, Journal Year: 2022, Volume and Issue: 11(21), P. 2976 - 2976

Published: Nov. 4, 2022

Abiotic stressors, such as drought, flooding, extreme temperature, soil salinity, and metal toxicity, are the most important factors limiting crop productivity. Plants use their innate biological systems to overcome these abiotic stresses caused by environmental edaphic conditions. Microorganisms that live in around plant have incredible metabolic abilities mitigating stress. Recent advances multi-omics methods, metagenomics, genomics, transcriptomics, proteomics, helped understand how plants interact with microbes environment. These methods aid construction of various models plants, resulting a better knowledge all exchanges engaged during interactions. Actinobacteria ubiquitous excellent candidates for growth promotion because prevalence soil, rhizosphere, capacity colonize roots surfaces, ability produce secondary metabolites. Mechanisms which actinobacteria stress include production osmolytes, hormones, enzymes, maintaining osmotic balance, enhancing nutrient availability. With characteristics, members promising microbial inoculants. This review focuses on actinobacterial diversity regions well impact plant-associated actinobacteria-mediated mitigation processes. The study discusses role techniques expanding plant–actinobacteria interactions, overcoming aims encourage further investigations into what may be considered relatively unexplored area research.

Agronomy, Journal Year: 2025, Volume and Issue: 15(1), P. 143 - 143

Published: Jan. 9, 2025

The carbon, nitrogen, phosphorus, and sulfur (CNPS) ratios of soils are known to be relatively stable parameters, characterizing different land uses. We hypothesized that the long-term application sewage sludge compost (SSC) would not change these but increase concentration elements quality organic matter (OM), as well soil enzyme activities. Hence, chemical microbiological properties were studied in a 20-year experiment. plots grouped into five blocks treated every third year with SSC at rates 0, 9, 18, or 27 t ha−1. Three plants, crop rotation, tested sown follows: rye, rye hairy vetch, maize. results showed basic parameters (pH, OM content, E4/E6 ratio, NO3-NO2-N, AL-P2O5, moisture content) increased, along doses for rye. Similar trends found CNPS concentrations, β-glucosidase, alkaline phosphatase activities, while acidic activity was reduced. C:N, C:S, N:S affected by application. main factors treatment effects plant-available phosphorus (ammonium lactate (AL)-soluble P2O5), total P, based on principal component analysis. canonical correspondent analyses revealed activities C:P, N:P β-glucosidase correlated P forms pH strongly all enzymes.
