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.
Potato late blight, caused by Phytophthora infestans , remains the most economically destructive disease of potato worldwide, yet the durability of chemical control is increasingly eroded by fungicide resistance and regulatory restriction. This study demonstrates that a rationally designed Bacillus – Pseud...
Verticillium dahliae is a destructive soil-borne fungus with a broad host range, and its persistence in soil complicates control. Current measures, mainly resistant cultivars and chemicals, are limited and environmentally risky, promoting biocontrol as a green alternative. Here, we investigated the biocontrol mechanism...
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.
Bacterial diseases of horticultural crops are difficult to manage because pathogens can multiply rapidly on or within susceptible tissues, exploit wounds and natural openings, persist in propagation material, and respond inconsistently to bactericides under field conditions. Endophytic bacteria offer a biologically dis...
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...
