Summary
This 2024 study investigates how Bacillus species regulate the citrus mycobiome via quorum quenching—a mechanism by which bacteria disrupt fungal cell-to-cell signalling. The research suggests that bacterial metabolic interference with fungal communication pathways shapes fungal community assembly and structure. The findings contribute to understanding microbial cross-kingdom interactions relevant to horticultural disease management and plant microbiome ecology.
UK applicability
The mechanisms described may be applicable to UK citrus production in protected environments and to understanding microbial interactions in other temperate horticultural crops. However, direct applicability would depend on whether similar Bacillus strains and fungal communities occur in UK growing conditions and whether the laboratory conditions translate to field-scale benefits.
Key measures
Fungal community composition, diversity indices, quorum quenching enzyme activity, interkingdom signalling molecules
Outcomes reported
The study examined how Bacillus species employ quorum quenching mechanisms to modulate fungal (mycobiome) composition in citrus plants through interkingdom signalling pathways. The research measured shifts in fungal community structure and diversity in response to bacterial quorum quenching activity.
