A four-strain synthetic microbial community, FSQN, applied to the rhizosphere soil and root microbiomes of rice (Oryza sativa) and compared with the single-strain Brevundimonas diminuta NH1 inoculant. FSQN was composed of Bacillus amyloliquefaciens FH1, Ochrobactrum tritici S112, Gluconacetobacter liquefaciens QZR14, and Brevundimonas diminuta NH1; after inoculation, high-throughput sequencing showed altered beta-diversity in rhizosphere soil and roots and functional predictions indicated enhanced ectomycorrhizal, endomycorrhizal, and plant-saprotrophic functions.

Ecological Interactions
The graph shows only explicitly linked interaction participants. Community members without an asserted participant link are omitted; membership alone does not imply an interaction.
FSQN-induced rice microbiome beta-diversity shift
FSQN inoculation significantly altered beta-diversity in rice rhizosphere soil and roots relative to the uninoculated control and enriched Mortierella, Tausonia, Fusarium, and Glomerella in rhizosphere soil plus Exiguobacterium, Pseudomonas, and Rhodotorula in roots.

FSQN-associated predicted fungal functional shift
Functional prediction of the FSQN-treated rice microbiome indicated enrichment of ectomycorrhizal, endomycorrhizal, and plant-saprotrophic functions.

Knowledge gaps & discussions (1)
KNOWLEDGE_GAP OPEN What were the growth medium, isolate sources, strain identities, inoculum ratios, and rice growth conditions used for the FSQN rice inoculation experiment?
The PubMed abstract names the four strains and the rice rhizosphere/root sequencing endpoints but does not expose the culture media, member isolation sources, inoculum ratio, or complete rice growth protocol needed to reproduce the FSQN treatment.
