Published: May 9, 2024

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.

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

Microbiome, Journal Year: 2024, Volume and Issue: 12(1)

Published: Aug. 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.

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

Journal of Integrative Plant Biology, Journal Year: 2025, Volume and Issue: unknown

Published: March 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.
