Other claims from this paper (11)
- Intervention effect Aspergillus niger ZJ-17 was previously reported to improve plant yield and quality while reducing fertilizer input in pot and field experiments.
- Intervention effect AN17 promoted nutrient utilization and absorption in rhizosphere soil.
- Intervention effect The relative abundance of rhizosphere Proteobacteria increased after AN17 inoculation.
- Observation A total of 832 bacterial strains were isolated from the rhizosphere of the host.
- Mechanism In in vitro experiments, AN17 induced enrichment of Proteobacteria through microbial interactions and modulation of host root exudates.
- Intervention effect Root exudates promoted the proliferation of bacterial genera with higher abundance and diversity.
- Intervention effect Host root activity increased following AN17 inoculation in the metabolome analysis.
- Intervention effect According to KEGG analysis of root exudates, AN17 upregulated microbial metabolism, biosynthesis of shikimate-derived alkaloids and tryptophan metabolism.
- Mechanism AN17 regulated the secretion of phenolic acids from roots, which are crucial components driving the enrichment of Proteobacteria.
- Intervention effect In plate and pot experiments, the isolated bacteria promoted growth of A. dahurica var. formosana and activated nutrient availability.
- Recommendation The authors state the result offers a sustainable approach for rhizosphere bacterial optimization and chemical fertilizer reduction in agricultural production.
