LuxR solos in Photorhabdus species

Frontiers in Cellular and Infection Microbiology, 2014
Bacteria communicate via small diffusible molecules to mediate group-coordinated behavior, a process designated as quorum sensing. The basic molecular quorum sensing system of Gram-negative bacteria consists of a LuxI-type autoinducer synthase producing ...

Genome analysis of secondary metabolite‑biosynthetic gene clusters of Photorhabdus akhurstii subsp. akhurstii and its antibacterial activity against antibiotic-resistant bacteria

PLoS ONE, 2022
Xenorhabdus and Photorhabdus can produce a variety of secondary metabolites with broad spectrum bioactivity against microorganisms. We investigated the antibacterial activity of Xenorhabdus and Photorhabdus against 15 antibiotic-resistant bacteria ...

Beware glowing cadavers: bioluminescence of nematode symbiont Photorhabdus protects nematode-infected host cadavers from nocturnal scavengers

Frontiers in Ecology and Evolution
Photorhabdus spp. are the only known terrestrial bioluminescent bacteria. We show that the bioluminescence produced by these bacteria reduces scavenging activity on the insect cadavers they colonize. Photorhabdus spp.

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

Agricultural and Forest Entomology, Volume 28, Issue 2, Page 298-313, May 2026.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

Isolation and identification of Xenorhabdus and Photorhabdus bacteria associated with entomopathogenic nematodes and their larvicidal activity against Aedes aegypti

Parasites & Vectors, 2017
Background Aedes aegypti is a potential vector of West Nile, Japanese encephalitis, chikungunya, dengue and Zika viruses. Alternative control measurements of the vector are needed to overcome the problems of environmental contamination and chemical ...

LuxS-dependent AI-2 production is not involved in global regulation of natural product biosynthesis in Photorhabdus and Xenorhabdus [PDF]

PeerJ, 2017
The Gram-negative bacteria Photorhabdus and Xenorhabdus are known to produce a variety of different natural products (NP). These compounds play different roles since the bacteria live in symbiosis with nematodes and are pathogenic to insect larvae in the

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Two Philippine Photorhabdus luminescens strains inhibit the in vitro growth of Lasiodiplodia theobromae, Fusarium oxysporum f. sp. lycopersici, and Colletotrichum spp.

Egyptian Journal of Biological Pest Control, 2021
Background Fungal phytopathogens are one of the leading causes of loss in global food production. Chemical fungicides have always been used to control the phytopathogens to mitigate losses.

Biological Degradation of Phthalates: From Bioremediation to Plastic Waste Valorization

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
Phthalic acid isomers play a key role in the plastics industry, but pose significant environmental and health concerns. This review explores the microbial biodegradation of phthalates and their esters, focusing on bacterial enzymes, catabolic pathways, and cellular uptake mechanisms of phthalates.
