SARD1 and CBP60g redundantly regulate N‐hydroxypipecolic acid‐ and salicylic acid‐dependent systemic immunity but are dispensable for the activation of indolic defense metabolism

The Plant Journal, Volume 127, Issue 6, September 2026.
SUMMARY We investigated the roles of the cognate, redundantly acting transcription factors SARD1 and CPB60g in the metabolic reprogramming of leaves of Arabidopsis thaliana suffering from bacterial infection or UV light exposure. Comprehensive metabolite analyses reveal that SARD1/CBP60g exert distinct influences on major stress‐inducible metabolic ...

Evaluation of the mosquitocidal activity of Photorhabdus and Xenorhabdus extracts against the larvae of Aedes aegypti (Diptera: Culicidae)

Journal of Entomological and Acarological Research
Aedes aegypti is the main vector for dengue viruses. Alternative control of this mosquito was proposed because of its resistance to chemical insecticides.

Photorhabdus sp. ETL Antimicrobial Properties and Characterization of Its Secondary Metabolites by Gas Chromatography–Mass Spectrometry

Life, 2021
Entomopathogenic nematodes (EPNs) are known to be highly pathogenic to insect pests, due to their associated symbiotic bacteria, which produce virulence factors, exo-enzymes and other harmful secondary metabolites to conquer, kill, and degrade their ...

Fragmentation of Vancoresmycin Reveals a Strong Dependence on Global Molecular Architecture for Antibacterial Activity

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Fragmentation of the natural product vancoresmycin reveals an essential role of global architecture for biological potency. Vancoresmycin is a structurally complex tetramic‐acid‐containing natural product with potent activity against Gram‐positive bacteria, yet its structure–activity relationships remain poorly defined.

The Drosophila melanogaster Metabolic Response against Parasitic Nematode Infection Is Mediated by TGF-β Signaling

Microorganisms, 2020
The nematode Heterorhabditis bacteriophora, its mutualistic bacterium Photorhabdus luminescens, and the fruit fly Drosophila melanogaster establish a unique system to study the basis of infection in relation to host metabolism.

Photorhabdus lux-operon heat shock-like regulation

Heliyon, 2023
For decades, transcription of Photorhabdus luminescens lux-operon was considered being constitutive. Therefore, this lux-operon has been used for measurements in non-specific bacterial luminescent biosensors.

Efficacy of Australian Entomopathogenic Nematodes Against the Pupal Stage of the Small Hive Beetle (Aethina tumida) Under Semi‐Field Conditions

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT The small hive beetle (SHB; Aethina tumida) is a major pest of honey bees that has threatened Australia's apiculture industry since its detection in 2002. Worryingly, the impact of SHB may be exacerbated by the recent establishment of Varroa destructor in eastern Australia.

Thermally Induced lux-Operon Promoter of Photorhabdus hainanensis and Photorhabdus temperata

Microorganisms
The bioluminescence of entomopathogenic bacteria of the genus Photorhabdus was considered to be constitutive. However, it has recently been shown that under heat shock conditions, lux-operon is activated in Photorhabdus temperata cells.
