TL;DR
This article examines quorum quenching (QQ), a broad anti-virulence biocontrol strategy that encompasses not only the enzymatic degradation of bacterial quorum-sensing signals (specifically N-acyl homoserine lactones or AHLs) but also the competitive blocking of signal production and perception.
These findings provide evidence for three complementary biological activities—synergistic antibiosis, suppression of selected pathogen virulence‐associated genes, and soil biochemical priming—that offers a transferable framework for microbial consortium engineering in sustainable potato production.
Investigation of the biocontrol mechanisms of Bacillus velezensis L33a against V. dahliae JR2 in tomato suggests that L33a is a promising biocontrol strain for green management of tomato Verticillium wilt.
While strain XJ-10 showed no detectable acylase activity, it exhibited significant degradation activity against AHL, suggesting a distinct QQ mechanism, and these findings broaden the scope of QQ-based biocontrol strategies and enhance mechanistic insights into managing bacterial diseases through QS modulation.
The strongest general conclusion is that endophytic competence can improve persistence and spatial proximity to infection courts, but endophytic residence alone does not guarantee effective disease control, and endophytic residence alone does not guarantee effective disease control.
This review critically synthesizes the ‘landscape’ of endophyte-mediated pest resistance through direct antagonism by insecticidal metabolites and enzymes, immune priming, signaling crosstalk, volatile organic compound-mediated indirect defense, and microbiome restructuring to provide a translational framework for movi...
Garlic root rot, mainly caused by Fusarium proliferatum, severely compromises yield and quality and causes substantial economic losses worldwide. Biocontrol using antagonistic bacteria has emerged as an efficient and sustainable strategy for managing this soil-borne disease. In this study, Bacillus velezensis xd3 was i...
