Abstract Background Plant-beneficial bacterial inoculants are of great interest in agriculture as they have the potential to promote plant growth and health. However, inoculation rhizosphere microbiome often results a suboptimal or transient colonization, which is due variety factors that influence fate inoculant. To better understand plant-beneficial complex microbiomes, composed by hundreds genotypes multifactorial selection mechanisms, controlled studies with high-complexity soil microbiomes needed. Results We analysed early compositional changes taxa-rich natural community under both exponential nutrient-rich stationary nutrient-limited conditions (i.e. growing stable communities, respectively) following bacterium Pseudomonas protegens bulk wheat environment. P. successfully established all tested was more abundant community. Nutrient availability major factor driving composition structure well underlying assembly processes. While access nutrients resulted communities assembled mainly homogeneous selection, stochastic processes dominated nutrient-deprived conditions. also observed an increased effect conditions, resulting higher number amplicon sequence variants (ASVs) whose relative abundance enriched. The produced discrete changes, some involved other . Direct competition between strains partially failed replicate differences pointed interaction network. Conclusions this study show nutrient force composition, diversity determines govern development. successful establishment inoculant facilitated among members microbiome. only explained indicating indirect interactions spatial distribution interface may be crucial for survival certain bacteria.

Unveiling Soil Microbiome Adaptation and Survival Strategy Under Vanadium Stress in Nationwide Mining Environments

Journal of Geophysical Research Biogeosciences, Journal Year: 2024, Volume and Issue: 129(7)

Published: July 1, 2024

Abstract In the soils of vanadium (V) smelters, a diverse array microorganisms relies on metabolic activities for survival amid stress. However, characteristics and functions soil microbiomes in V mining environments remain unexplored continental scale. This study thoroughly investigates microbial diversity, community assembly, functional potential microbiome across 90 smelters China. Alpha diversity decreases significantly along gradient, with emerging as primary factor influencing structure, followed by other environmental, climatic, geographic factors. The null model reveals that induces homogeneous selection, shaping co‐occurrence patterns leading to increased number positive associations, particularly keystone genera such f_Gemmatimonadaceae , Nocardioides Micromonospora Rubrobacter under higher concentrations (>559.6 mg/kg). Moreover, metagenomic analysis yields 67 metagenome‐assembled genomes, unraveling pathways taxa their likely involvement V(V) reduction process. Nitrate nitrite reductase ( nirK narG ), mtrABC are found be taxonomically affiliated . sp, FEN‐1250 etc. Additionally, reverse citric acid cycle (rTCA) serves carbon fixation pathway, synthesizing alternative energy putative reducers, highlighting potentially synergistic relationship between autotrophic heterotrophic processes supports survival. Our findings comprehensively uncover driving forces behind variation stress, revealing robust strategies possibly employed indigenous mitigate impact V. These insights hold applications bioremediation.

Combined application of arbuscular mycorrhizal fungi and selenium fertilizer increased wheat biomass under cadmium stress and shapes rhizosphere soil microbial communities

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: May 3, 2024

Abstract Background Selenium (Se) fertilizer and arbuscular mycorrhizal fungi (AMF) are known to modulate cadmium (Cd) toxicity in plants. However, the effects of their co-application on wheat growth soil microbial communities Cd-contaminated unclear. Results A pot experiment inoculation with two types AMF application Se under Cd stress showed that alone or combined significantly increased biomass. combination reduced available concentration soil, especially Ri treatment. High throughput sequencing samples indicated had stronger influence bacterial community compared fungal network seemed have more complex interconnections than network, finally shaped formation specific microflora affect availability. Conclusion These results indicate AMF, particularly combination, could successfully decrease availability relieve harm by modifying rhizosphere communities.
