Arbuscular mycorrhizal fungi and Streptomyces: brothers in arms to shape the structure and function of the hyphosphere microbiome in the early stage of interaction

Abstract Background Fungi and bacteria coexist in a wide variety of environments, their interactions are now recognized as the norm most agroecosystems. These microbial communities harbor keystone taxa, which facilitate connectivity between fungal bacterial communities, influencing composition functions. The roots plants associated with arbuscular mycorrhizal (AM) fungi, develop dense networks hyphae soil. surface these (called hyphosphere) is region where multiple can occur, e.g., exchanging or responding to each other’s metabolites. However, presence importance taxa AM hyphosphere remain largely unknown. Results Here, we used vitro pot cultivation systems fungi investigate whether certain were able shape growing potentially improved fitness host. Based on various soil leachates, synthetic found that under organic phosphorus (P) conditions, could selectively recruit enhanced P nutrition competed less P-mobilizing bacteria. Specifically, observed privileged interaction isolate Streptomyces sp. D1 genus Rhizophagus , (1) carbon compounds exuded by fungus acquired bacterium mineralize (2) culturable community residing was part regulated D1, primarily inhibiting weak P-mineralizing ability, thereby enhancing acquire P. Conclusions This work highlights multi-functionality fungal-bacteria bacterial-bacterial at hyphal fungi.

Bacillus species are core microbiota of resistant maize cultivars that induce host metabolic defense against corn stalk rot

Microbiome, Год журнала: 2024, Номер 12(1)

Опубликована: Авг. 23, 2024

Microbes colonizing each compartment of terrestrial plants are indispensable for maintaining crop health. Although corn stalk rot (CSR) is a severe disease affecting maize (Zea mays) worldwide, the mechanisms underlying host–microbe interactions across vertical compartments in plants, which exhibit heterogeneous CSR-resistance, remain largely uncharacterized. Here, we investigated microbial communities associated with CSR-resistant and CSR-susceptible cultivars using multi-omics analysis coupled experimental verification. Maize resistant to CSR reshaped microbiota recruited Bacillus species three phenotypes against Fusarium graminearum including niche pre-emption, potential secretion antimicrobial compounds, no inhibition alleviate pathogen stress. By inducing expression Tyrosine decarboxylase 1 (TYDC1), encoding an enzyme that catalyzes production tyramine dopamine, isolates do not directly suppress infection induced synthesis berberine, isoquinoline alkaloid inhibits growth. These beneficial bacteria were from rhizosphere transferred stems but grains plants. The current study offers insight into how respond interact their microbiome lays foundation preventing treating soil-borne pathogens.

Flavones enrich rhizosphere Pseudomonas to enhance nitrogen utilization and secondary root growth in Populus

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Фев. 7, 2025

Plant growth behavior is a function of genetic network architecture. The importance root microbiome variation driving plant functional traits increasingly recognized, but the mechanisms governing this are less studied. Here, we collect roots and rhizosphere soils from nine Populus species belonging to four sections (Leuce, Aigeiros, Tacamahaca, Turanga), generate metabolite transcription data for microbiota rhizospheres, conduct comprehensive multi-omics analyses. We demonstrate that vigorous Leuce poplar enrich more Pseudomonas, compared with poorly performing poplar. Moreover, confirm Pseudomonas strongly associated tricin apigenin biosynthesis identify gene GLABRA3 (GL3) critical secretion. elevated secretion via constitutive PopGL3 Chalcone synthase (PopCHS4) can drive colonization in further enhance growth, nitrogen acquisition, secondary development nitrogen-poor soil. This study reveals plant-metabolite-microbe regulation patterns contribute fitness thoroughly decodes key regulatory tricin, provides insights into interactions plant's metabolites its transcriptome microbes.

A simplified SynCom based on core–helper strain interactions enhances symbiotic nitrogen fixation in soybean

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Март 7, 2025

Synthetic microbial communities (SynComs) are a promising tool for making full use of the beneficial functions imparted by whole bacterial consortia. However, complexity reconstructed SynComs often limits their application in sustainable agriculture. Furthermore, inter-strain interactions neglected during SynCom construction. Here, we propose strategy constructing simplified and functional (sfSynCom) using elite helper strains that significantly improve core symbiotic strain, here Bradyrhizobium elkanii BXYD3, to sustain growth soybean (Glycine max). We first identified promote nodulation nitrogen fixation mediated BXYD3. Two these assigned Pantoea taxon produce acyl homoserine lactones, which enhanced colonization infection Finally, constructed sfSynCom from strains. This based on core-helper was more effective at promoting than inoculation with BXYD3 alone achieved effects comparable those complex previously basis potential between microbes plants alone. Our results suggest considering as well host plant might allow construction sfSynComs.
