The plant microbiome is an integral part of the host and increasingly recognized as playing fundamental roles in growth health. Increasing evidence indicates that rhizosphere recruits beneficial microbes to suppress soil-borne pathogens. However, ecological processes govern assembly functions below- aboveground compartments under pathogen invasion are not fully understood. Here, we studied bacterial fungal communities associated with 12 (e.g., soils, roots, stems, fruits) chili pepper (Capsicum annuum L.) using amplicons (16S ITS) metagenomics approaches at main production sites China investigated how Fusarium wilt disease (FWD) affects assembly, co-occurrence patterns, plant-associated microbiomes.The amplicon data analyses revealed FWD affected less on reproductive organs (fruit) than vegetative (root stem), strongest impact upper stem epidermis. Fungal intra-kingdom networks were stable their more sensitive communities. analysis microbial interkingdom network further indicated destabilized induced importance taxa. Although diseased plants susceptible colonization by other pathogenic fungi, can also recruit potential bacteria. Some taxa enriched identified core for microbiomes hub networks. On hand, metagenomic significant enrichment several functional genes involved detoxification, biofilm formation, plant-microbiome signaling pathways (i.e., chemotaxis) plants.Together, demonstrate a could bacteria mitigate changes organ facilitate or its offspring survival. may attract through modulation pathways. These findings significantly advance our understanding interactions provide important harnessing sustainable agriculture. Video abstract.

Evidence for the plant recruitment of beneficial microbes to suppress soil‐borne pathogens

New Phytologist, Год журнала: 2020, Номер 229(5), С. 2873 - 2885

Опубликована: Ноя. 1, 2020

Summary An emerging experimental framework suggests that plants under biotic stress may actively seek help from soil microbes, but empirical evidence underlying such a ‘cry for help’ strategy is limited. We used integrated microbial community profiling, pathogen and plant transcriptive gene quantification culture‐based methods to systematically investigate three‐way interaction between the wheat plant, wheat‐associated microbiomes Fusarium pseudograminearum ( Fp ). A clear enrichment of dominant bacterium, Stenotrophomonas rhizophila (SR80), was observed in both rhizosphere root endosphere Fp‐ infected wheat. SR80 reached 3.7 × 10 7 cells g −1 accounted up 11.4% microbes endosphere. Its abundance had positive linear correlation with load at base stems expression multiple defence genes top leaves. Upon re‐introduction soils, enhanced growth, below‐ground above‐ground, induced strong disease resistance by boosting above‐ground parts, only when present. Together, bacterium seems have acted as an early warning system defence. This work provides novel potential protection against pathogens enriched beneficial microbe via modulation immune system.

Genome-resolved metagenomics reveals role of iron metabolism in drought-induced rhizosphere microbiome dynamics

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Май 28, 2021

Abstract Recent studies have demonstrated that drought leads to dramatic, highly conserved shifts in the root microbiome. At present, molecular mechanisms underlying these responses remain largely uncharacterized. Here we employ genome-resolved metagenomics and comparative genomics demonstrate carbohydrate secondary metabolite transport functionalities are overrepresented within drought-enriched taxa. These data also reveal bacterial iron metabolism functionality is correlated with enrichment. Using time-series RNA-Seq data, homeostasis impacted by stress, loss of a plant phytosiderophore transporter impacts microbial community composition, leading significant increases lineage, Actinobacteria. Finally, show exogenous application disrupts drought-induced enrichment Actinobacteria, as well their improvement host phenotype during stress. Collectively, our findings implicate microbiome’s response may inform efforts improve tolerance increase food security.

Plants can recruit beneficial microbes to enhance their ability defend against pathogens. However, in contrast the intensively studied roles of rhizosphere microbiome suppressing plant pathogens, collective community-level change and effect phyllosphere response pathogen invasion remains largely elusive.Here, we integrated 16S metabarcoding, shotgun metagenomics culture-dependent methods systematically investigate changes between infected uninfected citrus leaves by Diaporthe citri, a fungal causing melanose disease worldwide. Multiple features suggested shift upon D. citri infection, highlighted marked reduction community evenness, emergence large numbers new microbes, intense microbial network. We also identified from functional perspectives leaves, such as enriched functions for iron competition potential antifungal traits, with genomic characteristics. Glasshouse experiments demonstrated that several bacteria associated could positively affect performance under challenge, reductions index ranging 65.7 88.4%. Among them, Pantoea asv90 Methylobacterium asv41 "recruited microbes" exhibited antagonistic activities both vitro vivo, including inhibition spore germination and/or mycelium growth. Sphingomonas spp. presented characteristics were found be main contributor enrichment complex outer membrane receptor protein leaves. Moreover, asv20 showed stronger suppression iron-deficient conditions than iron-sufficient conditions, suggesting role during action.Overall, our study revealed how microbiomes differed pathogen, mechanisms observed might have helped plants cope pressure. Our findings provide novel insights into understanding responses challenge. Video abstract.
