Reduced microbial stability in the active layer is associated with carbon loss under alpine permafrost degradation

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 118(25)

Significance Permafrost degradation may induce soil carbon (C) loss, critical for global C cycling, and be mediated by microbes. Despite larger stored within the active layer of permafrost regions, which are more affected warming, roles Qinghai–Tibet Plateau in most previous studies focused on high-latitude areas. Here, we demonstrate situ that alters diversity potentially decreases stability microbial communities. Additionally, these changes associated with loss a positive feedback. This study provides insights into microbial-mediated mechanisms responsible degraded permafrost, aiding modeling emission under future scenarios.

We have provided a framework to better understand the mechanisms governing balance between stochastic and deterministic processes integrate shifts in community assembly with microbial carbon metabolism. Our study reinforced that environmental filtering bacterial cooccurrence patterns influence stochastic/deterministic continuum of soil stochasticity may act through deeper layers Delineating theoretically potential linkages SOC dynamics across broad range systems represents an interesting topic for future research.

Specific metabolites drive the deterministic assembly of diseased rhizosphere microbiome through weakening microbial degradation of autotoxin

Microbiome, Год журнала: 2022, Номер 10(1)

Опубликована: Окт. 21, 2022

Abstract Background Process and function that underlie the assembly of a rhizosphere microbial community may be strongly linked to maintenance plant health. However, their processes functional changes in deterioration soilborne disease remain unclear. Here, we investigated features microbiomes related Fusarium wilt assessed by comparison pair diseased/healthy sequencing data. The untargeted metabolomics was employed explore potential drivers, shotgun metagenome used reveal mechanisms metabolite-mediated process after soil conditioning. Results showed deterministic associated with diseased microbiomes, this significantly correlated five metabolites (tocopherol acetate, citrulline, galactitol, octadecylglycerol, behenic acid). Application resulted microbiome high morbidity watermelon. Furthermore, metabolite conditioning found weaken autotoxin degradation undertaken specific bacterial group ( Bradyrhizobium , Streptomyces Variovorax Pseudomonas Sphingomonas ) while promoting metabolism small-molecule sugars acids initiated from another Anaeromyxobacter Bdellovibrio Conexibacter Flavobacterium Gemmatimonas ). Conclusion These findings suggest shifts underpin establishment avenues for future research focusing on ameliorating crop loss due pathogen.

Diversity, function and assembly of mangrove root-associated microbial communities at a continuous fine-scale

Abstract Mangrove roots harbor a repertoire of microbial taxa that contribute to important ecological functions in mangrove ecosystems. However, the diversity, function, and assembly root-associated communities along continuous fine-scale niche remain elusive. Here, we applied amplicon metagenome sequencing investigate bacterial fungal among four compartments (nonrhizosphere, rhizosphere, episphere, endosphere) roots. We found different distribution patterns for both all root compartments, which could be largely due differentiation exudation effects The functional pattern was also divergent within compartments. endosphere harbored more genes involved carbohydrate metabolism, lipid transport, methane production, fewer were sulfur reduction compared other dynamics revealed 56–74% derived from nonrhizosphere, whereas no OTUs nonrhizosphere detected endosphere. This indicates may play strictly selective role community community, is consistent with projections established an amplification-selection model. study reveals divergence diversity function niche, thereby highlighting soil-root interfaces shaping structure systems.
