The temporal and spatial dimensions of plant–soil feedbacks

New Phytologist, Год журнала: 2023, Номер 237(6), С. 2012 - 2019

Опубликована: Янв. 6, 2023

Feedbacks between plants and soil microbes form a keystone to terrestrial community ecosystem dynamics. Recent advances in dissecting the spatial temporal dynamics of plant-soil feedbacks (PSFs) have challenged longstanding assumptions spatially well-mixed microbial communities exceedingly fast assembly relative plant lifespans. Instead, PSFs emerge from interactions that are inherently mismatched scales, explicitly considering these is crucial understanding contribution foundational ecological patterns. I propose synthetic spatiotemporal framework for future research pairs experimental modeling approaches grounded mechanism improve predictability generalizability PSFs.

The role of rhizosphere phages in soil health

FEMS Microbiology Ecology, Год журнала: 2024, Номер 100(5)

Опубликована: Апрель 10, 2024

Abstract While the One Health framework has emphasized importance of soil microbiomes for plant and human health, one most diverse abundant groups—bacterial viruses, i.e. phages—has been mostly neglected. This perspective reviews significance phages health in rhizosphere explores their ecological evolutionary impacts on ecosystems. We first summarize our current understanding diversity roles terms nutrient cycling, top-down density regulation, pathogen suppression. then consider how drive bacterial evolution soils by promoting horizontal gene transfer, encoding auxiliary metabolic genes that increase host fitness, selecting phage-resistant mutants with altered ecology due to trade-offs competitiveness virulence. Finally, we challenges avenues phage research ecosystems elucidate microbial ecosystem functioning future. conclude similar bacteria, likely play important connecting different compartments, affecting microbiome functions soils. From applied perspective, could offer novel approaches modulate optimize microbe–plant interactions enhance health.

Recent advances in nano-enabled immunomodulation for enhancing plant resilience against phytopathogens

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Авг. 7, 2024

Plant diseases caused by microbial pathogens pose a severe threat to global food security. Although genetic modifications can improve plant resistance; however, environmentally sustainable strategies are needed manage diseases. Nano-enabled immunomodulation involves using engineered nanomaterials (ENMs) modulate the innate immune system of plants and enhance their resilience against pathogens. This emerging approach provides unique opportunities through ability ENMs act as nanocarriers for delivering immunomodulatory agents, nanoprobes monitoring immunity, nanoparticles (NPs) that directly interact with cells trigger responses. Recent studies revealed application nanoscale agrochemicals strengthen immunity biotic stress enhancing systemic resistance pathways, modulating antioxidant defense systems, activating defense-related pathways reshaping plant-associated microbiomes. However, key challenges remain in unraveling complex mechanisms which influence molecular networks, assessing long-term environmental impacts, developing biodegradable formulations, optimizing targeted delivery methods. review comprehensive investigation latest research on nano-enabled strategies, potential action, highlights future perspectives overcome existing disease management.

Serendipita indica Drives Sulfur-Related Microbiota in Enhancing Growth of Hyperaccumulator Sedum alfredii and Facilitating Soil Cadmium Remediation

Environmental Science & Technology, Год журнала: 2024, Номер 58(33), С. 14726 - 14739

Опубликована: Авг. 8, 2024

Endophytic fungus Serendipita indica can bolster plant growth and confer protection against various biotic abiotic stresses. However, S. indica-reshaped rhizosphere microecology interactions root–soil interface processes in situ at the submicrometer scale remain poorly understood. We combined amplicon sequencing high-resolution nano X-ray fluorescence (nano-XRF) imaging of root-soil to reveal cadmium (Cd) processes. successfully colonize roots Sedum alfredii Hance, which induces a remarkable increase shoot biomass by 211.32% Cd accumulation 235.72%. Nano-XRF images showed that colonization altered distribution facilitated proximity more sulfur (S) enter transport shoot. Furthermore, rhizosphere-enriched microbiota demonstrated stable network structure after inoculation. Keystone species were strongly associated with promotion absorption. For example, Comamonadaceae are closely related organic acid cycle S bioavailability, could facilitate plants. Meanwhile, Sphingomonadaceae release auxin boost biomass. In summary, we construct mutualism system for beneficial fungi hyperaccumulation plants, facilitates high-efficient remediation Cd-contaminated soils restructuring microbiota.

Abstract Vanadium (V) pollution potentially threatens human health. Here, it is found that nsp1 and nsp2 , Rhizobium symbiosis defective mutants of Medicago truncatula are sensitive to V. Concentrations phosphorus (P), iron (Fe), sulfur (S) with V negatively correlated in the shoots wild‐type R108, but not mutant shoots. Mutations P transporter PHT1 PHO1 VPT families, Fe IRT1 S SULTR1/3/4 family confer varying degrees tolerance on plants. Among these gene MtPT1 MtZIP6 MtZIP9 MtSULTR1; 1 R108 roots significantly inhibited by stress, while MtPHO1; 2 MtVPT2 MtVPT3 induced. Overexpression Arabidopsis thaliana VPT1 or M. increases plant tolerance. However, response genes weakened influenced soil microorganisms. NSPs reduce rhizobacterial diversity under stress simplify V‐responsive operational taxonomic unit modules co‐occurrence networks. Furthermore, recruits more beneficial rhizobacteria related V, P, Fe, than does . Thus, can modulate accumulation legumes through transporters, ion homeostasis, community responses.

Environmental Microbiome, Год журнала: 2024, Номер 19(1)

Опубликована: Июль 18, 2024

Abstract Background Climate change and anthropogenic activities intensify salinity stress impacting significantly on plant productivity biodiversity in agroecosystems. There are naturally salt-tolerant plants (halophytes) that can grow withstand such harsh conditions. Halophytes have evolved along with their associated microbiota to adapt hypersaline environments. Identifying shared microbial taxa between halophyte species has rarely been investigated. We performed a comprehensive meta-analysis using the published bacterial 16S rRNA gene sequence datasets untangle rhizosphere structure of two groups non-halophytes. aimed for identification marker being adapted high three independent approaches. Results Fifteen studies met selection criteria downstream analysis, consisting 40 representing diverse non-halophyte species. Microbiome structural analysis revealed distinct compositions halophytes face salt concentrations compared grown at low or from For concentrations, we discovered genera were independently detected through core microbiome, key hub by network random forest analysis. These Thalassospira , Erythrobacter Marinobacter . Conclusions Our level is critical factor affecting microbiome assembly plants. Detecting across high-halophytes may help select Bacteria might improve tolerance non-halophytic
